+==========================
+Configuring Firefox on Mac
+==========================
+Here we will add your Start9 server's Root CA (Certificate Authority) to your system's certificate trust store to ensure that applications can verify connections to your services.
+
+LAN Config
+----------
+#. Open Firefox and enter ``about:config`` in the URL bar. Accept any warnings that may appear about changing advanced configuration preferences.
+
+#. Search for *security.enterprise_roots.enabled* and double click on *false* so that it turns to *true*:

+      :width: 80%
+      :alt: Firefox security settings
+
+  Now restart Firefox (or other Mozilla application), and log in to your server using ``https``.  You should now see this symbol indicating a secure connection:
+
+    .. figure:: /_static/images/ssl/browser/firefox-https-good.png
+        :width: 80%
+        :alt: Firefox security settings
+
+.. tip:: If you see an exclamation point inside a triangle by the lock, you have made a security exception in the browser.  You will need to remove it by clicking the lock and then "Connection not secure":
+
+    .. figure:: /_static/images/ssl/browser/cert-trust-exception-remove-1.png
+        :width: 80%
+        :alt: Firefox - Remove security exception (Part 1)
+
+    Then click "Remove Exception":
+
+    .. figure:: /_static/images/ssl/browser/cert-trust-exception-remove-2.png
+        :width: 80%
+        :alt: Firefox - Remove security exception (Part 2)
+
+    You should now see that the website is trusted as in the final step show above.
+
+Tor Config
+----------
+.. caution::
+  This guide assumes you have completed :ref:`setting up Tor<tor-mac>`. Please visit this section first before you proceed as it is required for Firefox to properly work with Tor.
+
+#. Open Firefox and enter ``about:config`` in the URL bar. Accept any warnings that may appear about accessing advanced settings.
+
+#. Search for ``dom.securecontext.allowlist_onions`` and set the value to ``true``:
+
+   .. figure:: /_static/images/tor/firefox_allowlist.png
+    :width: 60%
+    :alt: Firefox whitelist onions screenshot
+
+#. Next, search for ``network.websocket.allowInsecureFromHTTPS`` and set the value to ``true``:
+
+    .. figure:: /_static/images/tor/firefox_insecure_websockets.png
+      :width: 60%
+      :alt: Firefox allow insecure websockets over https
+
+#. Now go to the right-hand hamburger menu and select ``Settings``:
+
+   .. figure:: /_static/images/tor/os_ff_settings.png
+    :width: 30%
+    :alt: Firefox options screenshot
+
+#. 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
+    :width: 60%
+    :alt: Firefox search screenshot
+
+#. Check the option labeled ``Use System Proxy Settings``
+
+#. Check the box labeled ``Proxy DNS when using SOCKS v5``:
+
+   .. figure:: /_static/images/tor/firefox_proxy.png
+    :width: 60%
+    :alt: Firefox proxy settings screenshot
+
+#. Click ``OK`` and then restart Firefox for the changes to take effect.
+
+#. You're all set! You should now be able to navigate to ``.onion`` URLs in Firefox.  You can test this by going to Start9's ``.onion`` homepage, `here <http://privacy34kn4ez3y3nijweec6w4g54i3g54sdv7r5mr6soma3w4begyd.onion/>`_.
