Add SmartTube for Android/Google/Fire TV on there too :D

Well, uhh, these requirements. But idk.

Yeah I’ve heard Arch is lightweight, but that might happen in like 5 years :D

Linux Mint is the easiest one from the list, but all of them except Solus are fine. I personally recommend Mint or Debian, Debian Sid if you want latest kernel.

No, I don’t really need it.

KDE should work fine, maybe with a bit of tweaking?

Mull also supports more extensions from developer options.

Check these out for Librewolf and Mull’s results. Fennec isn’t in the list (yet?)
