That being said, I am sad to see this fear of mine come true. Mozilla products were rock solid, and available on virtually every platform imaginable. I do not want to live in a Chromium and WebKit only world.
I didn't realize how much webgl and other cruft slowed things down until I started using librewolf.
The one improvement I'm hoping for is that the project would be checked into the official Debian/Ubuntu/Fedora package repos as those are less risky than the repo controlled by the developers.
Firefox sync is something you can enable, I believe
This has paid off incredibly well for them since anyone pointing out that it's primary purpose was to enrich the CEO while letting her band of merry women support their pet causes was called everything from a fascist to an incel.
Till today the most blatantly farcical situation was that Mozilla funded women who code boot-camps while firing all the women who code inside Mozilla.
I guess people are finally waking up when Mozilla pulled an Ubuntu and decided that everything you do through their software is something they own actually.
They also flag and harass anyone who points out the grift.
I think Mozilla has been a good example of that but the perception has been that resilience has been crumbling for years. Without an independent business model they have been in a really terrible position from the get-go.
That's one way to look at it, I guess. You could also look at it like a business model will inevitably enshittify.
