+# > and release manager working for Mozilla, I can confirm the statement
+# > that I made in
+# > https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=815006
+# >
+# > @garbas shared with me the list of patches applied for the Nix package.
+# > As they are just for portability and tiny modifications, they don't
+# > alter the experience of the product. In parallel, Rok also shared the
+# > build options. They seem good (even if I cannot judge the quality of the
+# > packaging of the underlying dependencies like sqlite, png, etc).

+        GNUzilla is the GNU version of the Mozilla suite, and GNU
+        IceCat is the GNU version of the Firefox web browser.
+
+        Notable differences from mainline Firefox:
+
+        - entirely free software, no non-free plugins, addons,
+          artwork,
+        - no telemetry, no "studies",
+        - sane privacy and security defaults (for instance, unlike
+          Firefox, IceCat does _zero_ network requests on startup by
+          default, which means that with IceCat you won't need to
+          unplug your Ethernet cable each time you want to create a
+          new browser profile without announcing that action to a
+          bunch of data-hungry corporations),
+        - all essential privacy and security settings can be
+          configured directly from the main screen,
+        - optional first party isolation (like TorBrowser),
+        - comes with HTTPS Everywhere (like TorBrowser), Tor Browser
+          Button (like TorBrowser Bundle), LibreJS, and SpyBlock
+          plugins out of the box.
+
+        This package can be installed together with Firefox and
+        TorBrowser, it will use distinct binary names and profile
+        directories.

+        This is a version of TorBrowser with bundle-related patches

+
+        I.e. it's a variant of Firefox with less fingerprinting and
+        some isolation features you can't get with any extensions.
+
+        Or, alternatively, a variant of TorBrowser that works like any
+        other UNIX program and doesn't expect you to run it from a
+        bundle.
+
+        It will use your default Firefox profile if you're not careful
+        even! Be careful!
+
+        It will clash with firefox binary if you install both. But it
+        should not be a problem because you should run browsers in
+        separate users/VMs anyway.
+
+        Create new profile by starting it as
+
+        $ firefox -ProfileManager
+
+        and then configure it to use your tor instance.
+
+        Or just use `tor-browser-bundle` package that packs this
