Tor Browser is "installed" differently on each supported operating system.

These instructions document the location of four important directories:

• User's profile directory
• Browser's code
• Tor client's configuration
• Tor client's code

Windows (32-bit and 64-bit)

On Windows, Tor Browser is by default installed to "%USERPROFILE%\Desktop\Tor Browser" (though a user can theoretically install it anywhere). If you have installed it somewhere besides the default, you will need to take that into account.

• User's profile directory:
  • "%USERPROFILE%\Desktop\Tor Browser\Browser\TorBrowser\Data\Browser\profile.default"
• Browser's code:
  • "%USERPROFILE%\Desktop\Tor Browser\Browser"
• Tor client's configuration:
  • "%USERPROFILE%\Desktop\Tor Browser\Browser\TorBrowser\Data\Tor"
• Tor client's code:
  • "%USERPROFILE%\Desktop\Tor Browser\Browser\TorBrowser\Tor"

MacOS

On MacOS (OS X), Tor Browser may be "installed" in a few different places.

If it is located in the system-wide Applications folder or in your Home directory under Applications (referred to as ~/Applications), then the above mentioned directories are located as follows:

• User's profile directory:
  • In Home: Library/Application Support/TorBrowser-Data/Browser/${something}.default/ (where ${something} is a random-looking 8-character string)
• Browser's code:
  • Tor Browser.app/Content/MacOS/
• Tor client's configuration:
  • In Home: Library/Application Support/TorBrowser-Data/Tor/
• Tor client's code:
  • Tor Browser.app/Content/MacOS/Tor/

If Tor Browser is installed in another folder (not /Applications or ~/Applications) then Tor Browser will create a TorBrowser-Data folder in that folder and the above mentioned directories are located as follows:

• User's profile directory:
  • TorBrowser-Data/Browser/${something}.default/ (where ${something} is a random-looking 8-character string)
• Browser's code:
  • Tor Browser.app/Content/MacOS/
• Tor client's configuration:
  • TorBrowser-Data/Tor/
• Tor client's code:
  • Tor Browser.app/Content/MacOS/Tor/

Linux (32-bit and 64-bit)

On Linux, Tor Browser is "installed" in a single, self-contained directory. For whichever locale is chosen (let's call the locale as ${LOCALE}; it may be de, en-US, zh-TW, etc.), the above mentioned directories are located as follows (and tor-browser_${LOCALE} may look like tor-browser_zh-CN):

• User's profile directory:
  • tor-browser_${LOCALE}/Browser/TorBrowser/Data/Browser/profile.default/
• Browser's code:
  • tor-browser_${LOCALE}/Browser/
• Tor client's configuration:
  • tor-browser_${LOCALE}/Browser/TorBrowser/Data/Tor/
• Tor client's code:
  • tor-browser_${LOCALE}/Browser/TorBrowser/Tor/
