+# Firefox
+
+## Build wrapped Firefox with extensions and policies
+
+The `wrapFirefox` function allows to pass policies, preferences and extension that are available to firefox. With the help of `fetchFirefoxAddon` this allows build a firefox version that already comes with addons pre-installed:
+
+```nix
+{
+  myFirefox = wrapFirefox firefox-unwrapped {
+    extraExtensions = [
+      (fetchFirefoxAddon {
+        name = "ublock";
+        url = "https://addons.mozilla.org/firefox/downloads/file/3679754/ublock_origin-1.31.0-an+fx.xpi";
+        sha256 = "1h768ljlh3pi23l27qp961v1hd0nbj2vasgy11bmcrlqp40zgvnr";
+      })
+    ];
+
+    extraPolicies = {
+      CaptivePortal = false;
+      DisableFirefoxStudies = true;
+      DisablePocket = true;
+      DisableTelemetry = true;
+      DisableFirefoxAccounts = true;
+      FirefoxHome = {
+        Pocket = false;
+        Snippets = false;
+      };
+       UserMessaging = {
+         ExtensionRecommendations = false;
+         SkipOnboarding = true;
+       };
+    };
+
+    extraPrefs = ''
+      // Show more ssl cert infos
+      lockPref("security.identityblock.show_extended_validation", true);
+    '';
+  };
+}
+```
