Introduction[edit]

Note: From Whonix ™ 14, Firefox-ESR is no longer installed by default and must be manually installed via Whonix-Workstation ™ Konsole for these instructions.

Non-Whonix ™ Platforms: If Firefox is available and Tor Browser is to be installed on a non-Whonix ™ platform, proceed to Download and Install Tor Browser. Otherwise, first install Firefox on the respective platform and configure the setting for clearnet onion connections, if desired.
Whonix: If Tor Browser is not installed, then it can be downloaded by using Firefox-ESR. Only complete this action for downloading Tor Browser and nothing else.
