             If connecting via Tor (i.e using the .onion address) the Bitwarden browser extension will only work with a Tor enabled browser. You can use Firefox (recommended), Tor Browser or Brave Browser.
 
             #. If you choose Firefox, you will need to :ref:`setup Tor on your device <tor-os>` and :ref:`configure Firefox to use Tor <tor-firefox>`. If using Brave you will just need to :ref:`setup Tor on your device <tor-os>`. With Tor Browser, everything will just work right out of the box.
