It's a non-story because you had to opt-in to Firefox's "experiments" feature to get the extension pushed to you. Opting in to the experiments feature is *literally* granting permission for Mozilla to change the behavior of your Firefox browser remotely in between official releases. So, Mozilla had your permission to change your browser. I simply will not shed a tear for anyone who felt betrayed by something they signed up for.
And, by the way, I was also "affected" by the Mr. Robot thing because I also opted in to the experiments feature.
Furthermore, the extension did nothing harmful. It didn't even collect any data as far as I know. You know why Mozilla pushed an extension that didn't even collect any data instead of one that does? Because they were acting in a trustworthy way!
Sure, it was a faux pax. Mozilla thought they could be cute the same way a lot of old school FLOSSy, hackery, software would include amusing Easter eggs and jokes. It was inappropriate and didn't land well for a variety of reasons, but there was no reason to lose trust in Mozilla at the time, and there's *certainly* no reason to even bring it up today, years later, when just about every other tech company and computer product is trying their damnedest to spy on you, sell your data, prevent you from having root control of your devices, and squeeze subscription money out of you.
Again, Chrome starts tracking you the instant you launch it for the first time. Microsoft tracks you when you log in to Windows and occasionally re-enables tracking features that you've disabled. Mozilla pushed a silly "fun" extension to users who opted in that didn't collect any data nor make Mozilla any money.
This discussion is nonsense. If you truly don't trust Mozilla after the harmless Mr. Robot extension was pushed to you after you chose to allow them to modify your browser remotely, then go ahead and stop using Firefox- I don't care. But please stop spreading FUD.
