+**************************************
+Setting up Firefox with Tor on Desktop
+**************************************
+
+.. warning::
+  This guide assumes you have completed :ref:`setting up Tor<running-tor>`. Please visit this section first before you proceed as it is required for Firefox to properly work with Tor.
+
+1. Open Firefox.
+
+2. Enter ``about:config`` in the URL bar. Accept any warnings that may appear about accessing advanced settings.
+
+3. Search for ``dom.securecontext.whitelist_onions`` and set the value to ``true``.

+
+4. Download a `Proxy Auto Config` file to inform Firefox how to use the Tor daemon running on your computer. You can get Start9's standard file by following the OS-specific instructions below:
+
+Windows:
+
+Click `here <https://registry.start9labs.com/sys/proxy.pac>`_ to get the file and save the file somewhere you won’t delete it. For this example:
+
+    .. code-block::
+
+      C:\Program Files\Tor Browser\proxy.pac
+
+Mac:
+
+Open the `Terminal` App on your Mac. You can find it in your list of Applications.  In the terminal, enter:
+
+    .. code-block::
+
+      brew install wget
+
+    And then:
+
+    .. code-block::
+
+      wget -P /usr/local/etc/tor https://registry.start9labs.com/sys/proxy.pac
+
+Linux:
+
+From a terminal, enter:
+
+    .. code-block::
+
+      sudo wget -P /etc/tor https://registry.start9labs.com/sys/proxy.pac
+
+
+5. Now open your Firefox web browser, and select options (Windows), or preferences (Mac/Linux):
+
+   .. figure:: /_static/images/tor/firefox_options_windows.png
+    :width: 80%
+    :alt: Firefox options screenshot
+
+    Select :menuselection:`Settings --> Options`
+
+
+6. Search for the term “proxy” in the search bar in the upper right, then select the button that says `Settings…`:
+
+   .. figure:: /_static/images/tor/firefox_search.png

+    :alt: Firefox search screenshot
+
+7. This should open a menu that will allow you to configure your proxy settings. Select `Automatic proxy configuration URL` and paste in the path to your PAC file from earlier, prefixed with ``file://``. For example:
+
+Windows:
+
+   .. code-block::
+
+    file://C:/Program Files/Tor Browser/proxy.pac
+
+Mac:
+
+   .. code-block::
+
+    file:///usr/local/etc/tor/proxy.pac
+
+Linux:
+
+   .. code-block::
+
+    file:///etc/tor/proxy.pac
+
+8. Then, check the box labeled `Proxy DNS when using SOCKS v5`:
+
+   .. figure:: /_static/images/tor/firefox_proxy.png
+    :width: 80%
+    :alt: Firefox proxy settings screenshot
+
+9. Click ``OK`` and then restart Firefox for the changes to take effect.
+
+10. You’re all set! You should now be able to navigate to `.onion` URLs in Firefox. This means you can bookmark Cups Messenger, and use your Bitwarden Tor address in the `Bitwarden Firefox Plugin <https://addons.mozilla.org/en-US/firefox/addon/bitwarden-password-manager/>`_.
