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.

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:
- See the Secure Connections page for important information on how to secure your connection when logging in.
- Tor Browser often makes your connection appear as though it is coming from an entirely different part of the world. Some websites, such as banks or email providers, might interpret this as a sign that your account has been hacked or compromised, and lock you out. The only way to resolve this is by following the site’s recommended procedure for account recovery, or contacting the operators and explaining the situation.
ZMĚNA IDENTITY A OKRUHU

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.
