Actually pretty good video.

• Search engine
• Google location service instead of their own (which they quit)
• FakeSpot & Pocket collecting crazy personalized data

Also info about difference between Mozilla Corporation and MZLA Nonprofit.

If you donate to Mozilla, nothing goes to Firefox. Instead they host petitions and beg big tech companies to be more transparent.

They dont focus on old users at all, and it seems they are unable to implement basic stuff.

I still recommend using Firefox, but with the Arkenfox userJS.

Or just use Librewolf.

Firefox is not usable. And dont donate to Mozilla I guess.
