Firefox through snap has been the last straw for me as well. Not quite enough to ragequit on the spot, but next time I have to install a new OS, it won't be Ubuntu.

why do you install it from snap? I'm using ubuntu and don't install from snap most of the time.

It's the default now.

Yup, and installing Firefox via apt installs a snap as well. I manually had to add a separate apt repo for Firefox alone. I seem to have to do this more and more for things that just can't be slow on my machine.

Yep, I did the same. But I don't want to mess around with hacks like that any more, so my next distro isn't going to be Ubuntu, even though I've used some Ubuntu variant for over a decade now. I'm looking at Tumbleweed for my next distro.

I like the security/privacy promises of options like snaps. It seems like other issues, like file sizes, aren’t the worst. And getting it to match your os options seems like a solvable problem. Could somebody explain why they hate these systems?

They live in the past of outdated security models.

I dislike snaps because they introduce inefficiencies and I don't want want applications to each bundle their own copies of the shared libraries they depend on. I also don't want automatic sandboxing.
