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.
