+Problem description: Tab-titles that are too long to fit into a tab get faded out.
+                     On big endian this is broken and instead of fading out, the 
+                     tab gets white and the font transparent, leading to an unreadable
+                     tab-title
+Solution: This is not a real solution, but a hack. The real solution would have been
+          to byte-swap the correct buffer, but I could not find it.
+          So the next best thing is to deactivate the fading-effect. Now all tab-titles
+          are readable, albeit not as pretty to look at as they could be. 
+Side-effects: I have not yet found an unwanted side-effect.

+For FF68, AntiAliasing of XULTexts seem to be broken on big endian (s390x). Text and icons of the sandwich-menu to the
+right of the address bar, as well as plugin-windows appears transparant, which usually means unreadable (white on white).

+Author: Greg V <greg@unrelenting.technology>
+Date:   Sun Dec 6 22:07:00 2020 +0000
+
+    Bug 1680982 - Use evdev instead of the Linux legacy joystick API for gamepads
+    
+    Using evdev is a prerequisite for adding rumble (haptic feedback) and LED support.
+    
+    - BTN_GAMEPAD semantic buttons are interpreted directly,
+    since all kernel drivers are supposed to use them correctly:
+    https://www.kernel.org/doc/html/latest/input/gamepad.html
+    - BTN_JOYSTICK legacy style numbered buttons use the model specific remappers
+    - we support even strange devices that combine both styles in one device
+    - the Linux gamepad module is enabled on FreeBSD and DragonFly, because
+    these kernels provide evdev, and libudev-devd provides enough of libudev
+    (evdev headers are provided by the devel/evdev-proto package)
+    
+    Differential Revision: https://phabricator.services.mozilla.com/D98868

+Tor Browser (TB) is a customized version of Firefox Extended Service
+Release built specifically for internet browsing over the Tor
+anonymity network.
+
+TB's configuration aims to mitigate attacks on a client's anonymity,
+including determining the client's actual IP address and browser
+fingerprinting.  Other aspects of Firefox have also been patched
+to plug privacy leaks in ways not possible any other way.
+
+You are recommended to install noscript extension manually,
+and read about TB and privacy from tor-project documentation.
+
+Remember that there are no perfect privacy or anonymity solutions, and
+this includes TB.  As always you must pay attention and in many cases
+modify your behavior to ensure your privacy online.
