O PROHLÍŽEČI TOR

Prohlížeč Tor používá síť Tor pro ochranu vašeho soukromí a anonymity. Používání sítě Tor má dvě hlavní vlastnosti:

Prohlížeč Tor je navíc navržen tak, aby zabránil webovým stránkám vytvářet "otisky" nebo identifikaci na základě konfigurace prohlížeče.

By default, Tor Browser does not keep any browsing history. Cookies are only valid for a single session (until Tor Browser is exited or a New Identity is requested).

JAK FUNGUJE TOR

Tor je síť virtuálních tunelů, která vám umožní zlepšit soukromí a bezpečnost na internetu. Tor funguje tak, že posílá vaši komunikaci prostřednictvím tří náhodných serverů (také známých jako "relays" v síti Tor. Poslední relay v okruhu ("výstupní relay") pošle provoz na veřejný internet.

Jak Tor funguje

Obrázek nahoře znázorňuje uživatele, který prohlíží různé webové stránky přes Tor. Zelené prostřední počítače představují relay v síti Tor, zatímco tři klíče představují vrstvy šifrování mezi uživatelem a každým relay.

STAHOVÁNÍ

Nejbezpečnější a nejjednodušší způsob, jak stáhnout Tor prohlížeč, je z oficiálního webu projektu Tor na adrese https://www.torproject.org/download. Your connection to the site will be secured using HTTPS, which makes it much harder for somebody to tamper with.

Nicméně mohou nastat situace, kdy nelze získat přístup na webové stránky projektu Tor: například, může být ve vaší síti blokován. Pokud k tomu dojde, můžete použít některý z alternativních způsobů stahování uvedený níže.

MIRRORS

Pokud nemůžete Prohlížeč Tor stáhnout z oficiální stránky, můžete zkusit stažení z alternativních umístění, skrze EFF nebo Calyx Institut.

GetTor

GetTor je služba, která automaticky odpovídá na emailové zprávy odkazy na poslední verzi Prohlížeče Tor, umístěné na mnoha místech, jako např. Dropbox, Google Drive a GitHub.

TO USE GETTOR VIA EMAIL

Pošlete email na gettor@torproject.org a v těle zprávy jednoduše napište “windows”, “osx”, nebo “linux” (bez uvozovek) podle toho, který operační systém používáte. Můžete přidat kód jazyka a bude stažen Prohlížeč Tor v jiném jazyce než anglickém. Například pro zobrazení odkazů pro stažení prohlížeč Tor v čínštině (Čína) pro Windows, pošlete email na gettor@torproject.org se zprávou "windows zh_CN".

GetTor odpoví e-mailem obsahujícím odkazy, ze kterých si můžete stáhnout balíček prohlížeče Tor, kryptografický podpis (potřebný pro ověření stahování), otisk klíče použitý k vytvoření podpisu a kontrolní součet balíčku. Možná vám bude nabídnuta možnost výběru "32bitového" nebo "64bitového" softwaru: to závisí na modelu počítače, který používáte.

PRVNÍ SPUŠTĚNÍ TORU

When you start Tor Browser, you will see the Connect to Tor window. This offers you the option to either connect directly to the Tor network, or to configure Tor Browser for your connection. There's a checkbox which asks whether you always want to get automatically connected to the Tor network, if this is the case, check the box.

PŘIPOJIT

Click 'connect' to connect to Tor

Ve většině případů vám zvolení "Připojit" umožní připojení k síti Tor bez jakéhokoliv dalšího nastavování.

Once clicked, a status bar will appear, showing Tor's connection progress. If you are on a relatively fast connection, but this bar seems to get stuck at a certain point, try the 'Connection Assist' or see the Troubleshooting page for help solving the problem. Or, if you know that your connection is censored or uses a proxy, you should click on "Tor Network Settings".

Click 'Tor Network Settings' to adjust network settings

CONNECTION ASSIST

If Tor is blocked in your location, trying a bridge may help. Connection Assist can choose one for you using your location.

Connection Assist automatic

If Connection Assist is unable to determine your location or you want to configure your connection manually instead, you can select your region from the dropdown menu and click on 'Try a Bridge'.

Connection Assist configuration

NASTAVIT

Tor prohlížeč vás provede řadou konfiguračních nastavení.

The Connection Assist informs you about the state of your Internet connection and your connection to the Tor network.

Connection Test success

Connection Test unsuccessful

The first checkbox is 'Quickstart'. If selected, every time you open Tor Browser, it will try to connect with your previous network settings.

Quickstart

If you know your connection is censored, or you have tried and failed to connect to the Tor network and no other solutions have worked, you can configure Tor Browser to use a pluggable transport. 'Bridges' will display the Circumvention section to configure a pluggable transport or to connect using Bridges.

Configure Tor bridge

OTHER OPTIONS

If your connection uses a proxy you can configure it by clicking on 'Settings ...' against 'Configure how Tor Browser connects to the Internet'. In most cases, this is not necessary. You will usually know if you need to select this checkbox because the same settings will be used for other browsers on your system. Pokud to je možné, požádejte správce sítě o radu. If your connection does not use a proxy, click "Connect".

Proxy settings for Tor Browser

OBCHÁZENÍ

Přímý přístup k síti Tor může být někdy cenzurován vaším dodavatelem internetového připojení nebo vládou. Tor Browser includes some circumvention tools for getting around these blocks. These tools are called “pluggable transports”.

TYPES OF PLUGGABLE TRANSPORT

Currently there are three pluggable transports available, but more are being developed.

obfs4 obfs4 makes Tor traffic look random, and also prevents censors from finding bridges by Internet scanning. obfs4 bridges are less likely to be blocked than its predecessors, obfs3 bridges.
meek meek transports make it look like you are browsing a major web site instead of using Tor. meek-azure makes it look like you are using a Microsoft web site.
Snowflake Snowflake is an improvement upon Flashproxy. It sends your traffic through WebRTC, a peer-to-peer protocol with built-in NAT punching.

USING PLUGGABLE TRANSPORTS

To use a pluggable transport, click "Configure Connection" when starting Tor Browser for the first time. Under the "Bridges" section, locate the option "Choose from Tor Browser's one of built-in bridges" and click on "Select a Built-In Bridge" option. From the menu, select whichever pluggable transport you'd like to use.

Once you've selected the pluggable transport, scroll up and click "Connect" to save your settings.

Or, if you have Tor Browser running, click on "Settings" in the hamburger menu (≡) and then on "Connection" in the sidebar. In the "Bridges" section, locate the option "Choose from Tor Browser's one of built-in bridges" and click on "Select a Built-In Bridge" option. Choose whichever pluggable transport you'd like to use from the menu. Your settings will automatically be saved once you close the tab.

Configure built-in bridges

WHICH TRANSPORT SHOULD I USE?

Each of the transports listed in Tor Bridge's menu works in a different way, and their effectiveness depends on your individual circumstances.

If you are trying to circumvent a blocked connection for the first time, you should try the different transports: obfs4, snowflake, or meek-azure.

If you try all of these options, and none of them gets you online, you will need to request a bridge or manually enter bridge addresses.

Users in China will likely have to connect with a private and unlisted obfs4 bridge. Contact our Telegram Bot @GetBridgesBot and type /bridges. Or send an email to frontdesk@torproject.org with the phrase "private bridge" in the subject of the email.

Read the Bridges section to learn what bridges are and how to obtain them.

MOSTY

Most Pluggable Transports, such as obfs4, rely on the use of "bridge" relays. Like ordinary Tor relays, bridges are run by volunteers; unlike ordinary relays, however, they are not listed publicly, so an adversary cannot identify them easily.

Using bridges in combination with pluggable transports helps to conceal the fact that you are using Tor, but may slow down the connection compared to using ordinary Tor relays.

Other pluggable transports, like meek, use different anti-censorship techniques that do not rely on bridges. You do not need to obtain bridge addresses in order to use these transports.

GETTING BRIDGE ADDRESSES

Because bridge addresses are not public, you will need to request them yourself. You have a few options:

USING MOAT

If you're starting Tor Browser for the first time, click on "Configure Connection" to open the Tor settings window. Under the "Bridges" section, locate "Request a bridge from torproject.org" and click on "Request a Bridge..." for BridgeDB to provide a bridge. Complete the Captcha and click "Submit". Click "Connect" to save your settings.

Or, if you have Tor Browser running, click on "Settings" in the hamburger menu (≡) and then on "Connection" in the sidebar. In the "Bridges" section, locate "Request a bridge from torproject.org" and click on "Request a Bridge..." for BridgeDB to provide a bridge. Complete the Captcha and click "Submit". Your setting will automatically be saved once you close the tab.

Request a bridge from torproject.org

ENTERING BRIDGE ADDRESSES

If you're starting Tor Browser for the first time, click "Configure Connection" to open the Tor settings window. Under the "Bridges" section, from the option "Enter a bridge address you already know" click on "Add a Bridge Manually" and enter each bridge address on a separate line. Click "Connect" to save your settings.

Or, if you have Tor Browser running, click on "Settings" in the hamburger menu (≡) and then on "Connection" in the sidebar. In the "Bridges" section, from the option "Enter a bridge address you already know" click on "Add a Bridge Manually" and enter each bridge address on a separate line. Your settings will automatically be saved once you close the tab.

Enter bridge addresses manually

If the connection fails, the bridges you received may be down. Please use one of the above methods to obtain more bridge addresses, and try again.

BRIDGE-MOJI

Each bridge address is represented by a string of emoji characters called Bridge-mojis. The Bridge-mojis can be used to validate that the intended bridge has been added successfully.

Bridge-mojis are human-readable bridge identifiers and do not represent the quality of connection to the Tor network or the state of the bridge. The string of emoji characters cannot be used as input. Users are required to provide the complete bridge address to be able to connect with a bridge.

Bridge-moji

The bridge addresses can be shared using the QR code or by copying the entire address.

Bridge QR code

SPRÁVA IDENTIT

Když se připojíte k webovému serveru, nemusí provozovatel zaznamenávat pouze informace o vaší návštěvě. Většina webových stránek nyní využívá řadu služeb třetích stran, včetně sociálních sítí, tlačítek typu "Líbí se mi", sledovacích nástrojů pro analýzu a reklamních majáků, které mohou všechny vaše aktivity propojit na různých webech.

Použití sítě Tor zastaví pozorovatele, aby nebyli schopni zjistit přesnou polohu a IP adresu, ale i bez těchto informací by mohli spojit různé oblasti vaší činnosti dohromady. Z tohoto důvodu prohlížeč Tor obsahuje některé další funkce, které vám pomohou řídit, jaké informace mohou být spojeny s vaší totožností.

THE URL BAR

Tor Browser centers your web experience around your relationship with the website in the URL bar. Even if you connect to two different sites that use the same third-party tracking service, Tor Browser will force the content to be served over two different Tor circuits, so the tracker will not know that both connections originate from your browser.

On the other hand, all connections to a single website address will be made over the same Tor circuit, meaning you can browse different pages of a single website in separate tabs or windows, without any loss of functionality.

Display circuit diagram under the site information menu

You can see a diagram of the circuit that Tor Browser is using for the current tab in the site information menu, in the URL bar.

In the circuit, the Guard or entry node is the first node and it's automatically and randomly selected by Tor. But it is different from the other nodes in the circuit. In order to avoid profiling attacks, the Guard node changes only after 2-3 months, unlike the other nodes, which change with every new domain. For more information about Guards, consult the FAQ and Support Portal.

LOGGING IN OVER TOR

Although Tor Browser is designed to enable total user anonymity on the web, there may be situations in which it makes sense to use Tor with websites that require usernames, passwords, or other identifying information.

If you log into a website using a regular browser, you also reveal your IP address and geographical location in the process. The same is often true when you send an email. Logging into your social networking or email accounts using Tor Browser allows you to choose exactly which information you reveal to the websites you browse. Logging in using Tor Browser is also useful if the website you are trying to reach is censored on your network.

Pokud se přihlásíte na web přes Tor, je několik bodů, které byste měli mít na paměti:

ZMĚNA IDENTITY A OKRUHU

New Identity and New Tor Circuit options under main menu

Tor Browser features “New Identity” and “New Tor Circuit for this Site” options. They are also located in the hamburger or main menu (≡).

NOVÁ IDENTITA

Tato volba je užitečná, pokud chcete zabránit tomu, aby následná aktivita prohlížeče byla spojena s tím, co jste dělali předtím. Jejím výběrem zavřete všechny otevřené panely a okna, vymažete všechny soukromé informace, jako jsou cookies a historie prohlížení, a pro všechna nové připojení se použijí nové okruhy Toru. Prohlížeč Tor vás upozorní, že veškerá činnost a stahování budou zastaveny.

To use this option, you just need to click on 'New Identity' in Tor Browser's toolbar.

NOVÝ OKRUH TOR PRO TUTO STRÁNKU

This option is useful if the exit relay you are using is unable to connect to the website you require, or is not loading it properly. Selecting it will cause the currently-active tab or window to be reloaded over a new Tor circuit. Other open tabs and windows from the same website will use the new circuit as well once they are reloaded. This option does not clear any private information or unlink your activity, nor does it affect your current connections to other websites.

You can also access this option in the new circuit display, in the site information menu, in the URL bar.

ONION SERVICES

Onion services (formerly known as "hidden services") are services (like websites) that are only accessible through the Tor network.

Onion services offer several advantages over ordinary services on the non-private web:

HOW TO ACCESS AN ONION SERVICE

Just like any other website, you will need to know the address of an onion service in order to connect to it. An onion address is a string of 56 letters and numbers, followed by ".onion".

When accessing a website that uses an onion service, Tor Browser will show in the URL bar an icon of an onion displaying the state of your connection: secure and using an onion service. You can learn more about the onion site that you are visiting by looking at the Circuit Display.

Another way to learn about an onion site is if the website administrator has implemented a feature called Onion-Location. Onion-Location is a non-standard HTTP header that websites can use to advertise their onion counterpart. If the website that you are visiting has an onion site available, a purple suggestion pill will prompt at the URL bar in Tor Browser displaying ".onion available". When you click on ".onion available", the website will be reloaded and redirected to its onion counterpart.

Onion-Location

To prioritize an onion site version of a website, you can enable automatic Onion-Location redirects. Click on hamburger menu (≡), go to Preferences (or Options on Windows), click on Privacy & Security, and in the Onion Services section look for the entry "Prioritize .onion sites when known." and check the option "Always". Or, if you're already running Tor Browser, you can copy and paste this string in a new tab: about:preferences#privacy and change this setting.

ONION SERVICE AUTHENTICATION

An authenticated onion service is a service like an onion site that requires the client to provide an authentication token before accessing the service. As a Tor user, you may authenticate yourself directly in the Tor Browser. In order to access this service, you will need access credentials from the onion service operator. When accessing an authenticated onion service, Tor Browser will show in the URL bar an icon of a little gray key, accompanied by a tooltip. Enter your valid private key into the input field.

Client Authorization

ONION SERVICES ERRORS

If you can't connect to an onion site, Tor Browser will provide a specific error message informing why the website is unavailable. Errors can happen in different layers: client errors, network errors or service errors. Some of these errors can be fixed by following the Troubleshooting section. The table below shows all the possible errors and which action you should take to solve the issue.

Code Error Title Short Description
0xF0 Onionsite Not Found The most likely cause is that the onionsite is offline. Contact the onionsite administrator.
0xF1 Onionsite Cannot Be Reached The onionsite is unreachable due an internal error.
0xF2 Onionsite Has Disconnected The most likely cause is that the onionsite is offline. Contact the onionsite administrator.
0xF3 Unable to Connect to Onionsite The onionsite is busy or the Tor network is overloaded. Try again later.
0xF4 Onionsite Requires Authentication Access to the onionsite requires a key but none was provided.
0xF5 Onionsite Authentication Failed The provided key is incorrect or has been revoked. Contact the onionsite administrator.
0xF6 Invalid Onionsite Address The provided onionsite address is invalid. Please check that you entered it correctly.
0xF7 Onionsite Circuit Creation Timed Out Failed to connect to the onionsite, possibly due to a poor network connection.

TROUBLESHOOTING

If you cannot reach the onion service you requested, make sure that you have entered the onion address correctly: even a small mistake will stop Tor Browser from being able to reach the site.

If you are still unable to connect to the onion service after verifying the address, please try again later. There may be a temporary connection issue, or the site operators may have allowed it to go offline without warning.

If the onion service you are trying to access consists of a string of 16 characters (V2 format), this type of address is being deprecated.

You can also test if you are able to access other onion services by connecting to DuckDuckGo's Onion Service.

ZABEZPEČENÁ PŘIPOJENÍ

If personal information such as a login password travels unencrypted over the Internet, it can very easily be intercepted by an eavesdropper. If you are logging into any website, you should make sure that the site offers HTTPS encryption, which protects against this kind of eavesdropping. You can verify this in the URL bar: if your connection is encrypted, the address will begin with “https://”, rather than “http://”.

HTTPS-Only Mode in Tor Browser

HTTPS-Only mode forces all connections to websites to use a secure encrypted connection called HTTPS. Most websites already support HTTPS; some support both HTTP and HTTPS. Enabling this mode guarantees that all of your connections to websites are upgraded to use HTTPS and hence secure.

HTTPS-only mode in Tor Browser

Some websites only support HTTP and the connection cannot be upgraded. If a HTTPS version of a site is not available, you will see a “Secure Connection Not Available” page:

Secure Connection not available when HTTP website

If you click 'Continue to HTTP Site' you accept the risk and then will visit a HTTP version of the site. HTTPS-Only Mode will be turned off temporarily for that site.

Click the 'Go Back' button if you want to avoid any unencrypted connections.

NASTAVENÍ ZABEZPEČENÍ

By default, Tor Browser protects your security by encrypting your browsing data. You can further increase your security by choosing to disable certain web features that can be used to compromise your security and anonymity. You can do this by increasing Tor Browser's Security Levels in the shield menu. Increasing Tor Browser's security level will stop some web pages from functioning properly, so you should weigh your security needs against the degree of usability you require.

ACCESSING THE SECURITY SETTINGS

The Security Settings can be accessed by clicking the Shield icon next to the Tor Browser URL bar. To view and adjust your Security Settings, click the 'Change...' button in the shield menu.

Click on 'Change' under the shield menu

SECURITY LEVELS

Increasing the Security Level in the Tor Browser Security Settings will disable or partially disable certain browser features to protect against possible attacks. You can enable these settings again at any time by adjusting your Security Level.

Security Level is currently set to Safest

Standard

ODSTRAŇOVÁNÍ PROBLÉMŮ

You should be able to start browsing the web using Tor Browser shortly after running the program, and clicking the “Connect” button if you are using it for the first time.

Click 'Connect' to connect to Tor

The Connection Assist informs you about the state of your Internet connection if you click on 'Test'.

QUICK FIXES

If Tor Browser doesn’t connect, there may be a simple solution. Try each of the following:

VIEW TOR LOGS

In most cases, taking a look at the Tor logs can be helpful in diagnosing the issue. If you’re having trouble connecting, an error message may appear and you can select the option to "copy Tor log to clipboard". Then paste the Tor log into a text file or other document.

If you don't see this option and you have Tor Browser open, you can navigate to the hamburger menu ("≡"), then click on "Settings", and finally on "Connection" in the side bar. At the bottom of the page, next to the "View the Tor logs" text, click the button "View Logs...".

Alternatively, on GNU/Linux, to view the logs right in the terminal, navigate to the Tor Browser directory and launch the Tor Browser from the command line by running:

./start-tor-browser.desktop --verbose

Or to save the logs to a file (default: tor-browser.log):

./start-tor-browser.desktop --log [file]

More information on this can be found on the Support Portal.

IS YOUR CONNECTION CENSORED?

If you still can’t connect, your Internet Service Provider might be censoring connections to the Tor network. Read the Circumvention section for possible solutions.

KNOWN ISSUES

Tor Browser is under constant development, and some issues are known about but not yet fixed. Please check the Known Issues page to see if the problem you are experiencing is already listed there.

AKTUALIZACE

Tor prohlížeč musí být neustále aktualizován. Pokud budete nadále používat zastaralou verzi softwaru, můžete být ohroženi vážnými bezpečnostními nedostatky, které ohrožují vaše soukromí a anonymitu.

Tor Browser will prompt you to update the software once a new version has been released: the main menu (≡) will display a green circle with an upwards facing arrow in it, and you may see a written update indicator when Tor Browser opens. You can update either automatically or manually.

UPDATING TOR BROWSER AUTOMATICALLY

Select 'Restart to update Tor Browser' under the main menu

When you are prompted to update Tor Browser, click on the main menu (≡), then select “Restart to update Tor browser”.

Update progress bar

Wait for the update to download and install, then Tor Browser will restart itself. You will now be running the latest version.

UPDATING TOR BROWSER MANUALLY

Když jste vyzváni k aktualizaci prohlížeče Tor, dokončete prohlížení a zavřete program.

Remove Tor Browser from your system by deleting the folder that contains it (see the Uninstalling section for more information).

Visit https://www.torproject.org/download/ and download a copy of the latest Tor Browser release, then install it as before.

PLUGINS, ADD-ONS AND JAVASCRIPT

FLASH PLAYER

Video websites, such as Vimeo make use of the Flash Player plugin to display video content. Unfortunately, this software operates independently of Tor Browser and cannot easily be made to obey Tor Browser’s proxy settings. It can therefore reveal your real location and IP address to the website operators, or to an outside observer. For this reason, Flash is disabled by default in Tor Browser, and enabling it is not recommended.

Some video websites (such as YouTube) offer alternative video delivery methods that do not use Flash. These methods may be compatible with Tor Browser.

JAVASCRIPT

JavaScript is a programming language that websites use to offer interactive elements such as video, animation, audio, and status timelines. Unfortunately, JavaScript can also enable attacks on the security of the browser, which might lead to deanonymization.

Tor Browser includes an add-on called NoScript. It's accessible through "Preferences" (or "Options" on Windows) on the hamburger menu (≡), then select 'Customize' and drag the “S” icon to the top-right of the window. NoScript allows you to control the JavaScript (and other scripts) that runs on individual web pages, or block it entirely.

Users who require a high degree of security in their web browsing should set Tor Browser’s Security Level to “Safer” (which disables JavaScript for non-HTTPS websites) or “Safest” (which does so for all websites). However, disabling JavaScript will prevent many websites from displaying correctly, so Tor Browser’s default setting is to allow all websites to run scripts in "Standard" mode.

BROWSER ADD-ONS

Tor Browser is based on Firefox, and any browser add-ons or themes that are compatible with Firefox can also be installed in Tor Browser.

However, the only add-ons that have been tested for use with Tor Browser are those included by default. Installing any other browser add-ons may break functionality in Tor Browser or cause more serious problems that affect your privacy and security. It is strongly discouraged to install additional add-ons, and the Tor Project will not offer support for these configurations.

ODINSTALACE

Odebrání prohlížeče Tor ze systému je jednoduché:

On Windows:

On macOS:

Go to folder menu option

Go to folder window

Note that if you did not install Tor Browser in the default location (the Applications folder), then the TorBrowser-Data folder is not located in the ~/Library/Application Support/ folder, but in the same folder where you installed Tor Browser.

Na Linuxu:

Note that your operating system’s standard "Uninstall" utility is not used.

When Tor Browser is running, you would see so in your device's notification panel after expanding it along with the button "NEW IDENTITY". Tapping on this button will provide you with a new identity. Unlike in Tor Browser for Desktop, the "NEW IDENTITY" button in Tor Browser for Android does not prevent your subsequent browser activity from being linkable to what you were doing before. Selecting it will only change your Tor circuit.

SECURITY SETTINGS

Security settings and security slider on Tor Browser for Android

Security settings disable certain web features that can be used to compromise your security and anonymity. Tor Browser for Android provides the same three security levels that are available on desktop. You can modify the security level by following given steps:

UPDATING

Tor prohlížeč musí být neustále aktualizován. Pokud budete nadále používat zastaralou verzi softwaru, můžete být ohroženi vážnými bezpečnostními nedostatky, které ohrožují vaše soukromí a anonymitu. You can update Tor Browser automatically or manually.

Updating Tor Browser for Android automatically

This method assumes that you have either Google Play or F-Droid installed on your mobile device.

Google Play

Updating Tor Browser for Android on Google Play

Tap on the hamburger menu next to the search bar and navigate to "My apps & games" > "Updates". If you find Tor Browser on the list of apps which need updating, select it and tap the "Update" button.

F-Droid

Updating Tor Browser for Android on F-Droid

Tap on "Settings", then go to "Manage installed apps". On the next screen, select Tor Browser and finally tap on the "Update" button.

Updating Tor Browser for Android manually

Visit the Tor Project website and download a copy of the latest Tor Browser release, then install it as before. In most cases, this latest version of Tor Browser will install over the older version, thereby upgrading the browser. If doing this fails to update the browser, you may have to uninstall Tor Browser before reinstalling it. With Tor Browser closed, remove it from your system by uninstalling it using your device's settings. Depending on your mobile device's brand, navigate to Settings > Apps, then select Tor Browser and tap on the "Uninstall" button. Afterwards, download the latest Tor Browser release and install it.

UNINSTALLING

Tor Browser for Android can be uninstalled directly from F-Droid, Google Play or from your mobile device's app settings.

Google Play

Uninstalling Tor Browser for Android on Google Play

Tap on the hamburger menu next to the search bar and navigate to "My apps & games" > "Installed". Select Tor Browser from the list of installed apps, then press the "Uninstall" button.

F-Droid

Uninstalling Tor Browser for Android on F-Droid

Tap on "Settings", then go to "Manage installed apps". On the next screen, select Tor Browser and finally tap on the "Uninstall" button.

Mobile device app settings

KNOWN ISSUES

At the moment, there are some features which are not available in Tor Browser for Android, but are currently available in Tor Browser for desktop.

More about Tor on mobile devices

Orfox

Orfox was first released in 2015 by The Guardian Project, with the aim of giving Android users a way to browse the internet over Tor. Over the next three years, Orfox continuously improved and became a popular way for people to browse the internet with more privacy than standard browsers, and Orfox was crucial for helping people circumvent censorship and access blocked sites and critical resources. In 2019, Orfox was sunsetted after the official Tor Browser for Android was released.

Orbot

Orbot is a free proxy app that empowers other apps to use the Tor network. Orbot uses Tor to encrypt your Internet traffic. Then you can use it with other apps installed on your mobile device to circumvent censorship and protect against surveillance. Orbot can be downloaded and installed from Google Play. Check out our Support portal to know if you need both Tor Browser for Android and Orbot or either one.

Tor Browser for iOS

There is no Tor Browser for iOS. We recommend an iOS app called Onion Browser, which is open source, uses Tor routing, and is developed by someone who works closely with the Tor Project. However, Apple requires browsers on iOS to use something called Webkit, which prevents Onion Browser from having the same privacy protections as Tor Browser.

Learn more about Onion Browser. Download Onion Browser from the App Store.

Tor Browser for Windows Phone

There is currently no supported method for running Tor on older Windows Phones but in case of the newer Microsoft-branded/promoted phones, same steps on Tor Browser on Android can be followed.
