On an unrelated note, I use Time Machine and I’m surprised at how unpolished, not to say downright buggy, all the animations are. They used to look magical, but now they are a mess of elements popping on and off and things moving and then vanishing the next frame and so on. It looks like they kept changing Finder and Time Machine didn’t keep up; they kept fixing the bare minimum to have it compile and nothing more.
Correct. You have to spend a while in settings disabling stuff.
The browser does not re-enable the things you have disabled, but they keep implementing new stuff that you have to disable too.
It’s annoying, although that’s how most software works nowadays (and I include Firefox unfortunately). You have to disable a lot of stuff to make it usable.
