I am doubly pissed off:

• Mozilla opts me into an analytics scheme without requiring my permission. That's bad.
• Mozilla partners with fucking FACEBOOK to spring this shit on me? Now THAT takes the cake!

But... I would be pissed off if I used straight Firefox, and I don't: I use LibreWolf, and I have no doubt they'll strip this latest round of Mozilla nonsense from the LibreWolf browser.

I don't know... I have a love/hate relationship with Mozilla: on the one hand, they're pretty much the only thing that stands between the final overrun of the web by the Google monoculture and still having some kind of a choice what you use to hit the internet, and they make one of the only email clients worth its salt in Linux. On the other hand, every time they decide to do something, it's always a screw-up, and it's been like that for decades. Surely in their position, they should know what not to do to piss off everybody all the time, and yet... What a weird bunch.
