Description:
<!-- Uncomment relevant sections and delete options which are not applicable -->

#### Testing the changes
- I tested the changes in this PR: **briefly**

~I currently dont have the space to build and test this locally, but~ I wanted to at least start it off since apparently a somewhat important issue from 102 version was fixed -> https://bugzilla.mozilla.org/show_bug.cgi?id=1781167

Feel free to close this again, or use it for testing (there were also some language packs missing which I added)
