Tor Browser does not affect any of the existing software or settings on your computer. Uninstalling Tor Browser will not affect your system’s software or settings.
Removing Tor Browser from your system is simple:
Locate your Tor Browser folder. The default location on Windows is the Desktop; on macOS it is the Applications folder. On Linux, there is no default location, however the folder will be named "tor-browser_en-US" if you are running the English Tor Browser.
Delete the Tor Browser folder.
Empty your Trash
Note that your operating system’s standard “Uninstall” utility is not used.
