It's easy to look at the actions of the last few years as if they are the exception, but this has been going on for a long time and Mozilla was given a slide for "reasons"
That's a hard thing for a lot of Firefox's userbase to swallow, their dream being a pristine FOSS project essentially run as donationware. Nonfree things, monetization etc. just really don't sit well with that lot. I know, I was one of the people whining about Pocket when it was integrated into the browser and didn't see the point of it. Now? If Firefox is to live, more things like Pocket need to happen.
Opt-out keylogging in a privacy browser isn't that, though.
So far so good, it seems.
TBB looks like Firefox, is that why? Kali makes appearances, too (albeit as an everyday desktop OS).
Just to clarify, Servo was never a part of Firefox. Maybe that's not what you meant, but I've seen it confused with Gecko before which is the actual browser engine used by Firefox.
And as much as I am puzzled by some of the design choices lately - for the android version of Firefox especially - I think that it would be a loss in more ways than one to lose the last (?) real alternative to the Chromium-based family of browsers.
But Servo, to the best of my knowledge, was* an R&D project to develop an new experimental engine. The parts lifted into Firefox are now presumably maintained and developed as a part of Firefox proper.
Don't get me wrong, I was disappointed when i heard that the Servo team was laid off. We are probably missing out on new exciting things that could have come out of it. I just wanted to clarify that cutting Servo did not, as far as I know, mean that any current part of Firefox is now unmaintained or undeveloped.
* Servo is still alive and developed outside of Mozilla, I don't know if's doing well or not.
And when they recently saw the need to tighten the belts, they fired the people working on core parts of the browser (Servo) as well as those working on the crucial browser documentation on MDN.
Adding spyware and ads to the browser is just the rotten cherry on top of the excrement sundae they expect us to eat.
After using Firefox since it first came out, I recently switched to Vivaldi. It’s Chromium-based these days, but with much of the same configurability and flexibility that I loved about Firefox, and the people behind it at least appear to have their hearts in the right place.
