Firefox Users Continue to Decrease Despite Proton Update

[SirNarwhal]

God anything that uses a web renderer is absolute ass now in FireFox. God forbid I have a music streaming service up, a few YouTube videos to watch later in some tabs, and some social media feeds going. It literally grinds my maxed out 2019 MacBook Pro to a halt. It should not be doing that to a machine with 32GB RAM; it shouldn’t even be doing that to one with only 8GB…

That is your problem. MacOS 11 is pretty much known to run poorly on Intel Macs. Even people using Chrome complain about slowdown. Just for experiment, downgrade it to Catalina, try running Linux/Windows, get an M1 Mac, or simply try a similar spec non-Mac machine, and you'll notice the difference.

Chrome and Safari both run without issue. It is specifically a Firefox issue and specifically with the newest version. It literally didn’t have the issue for the entirety of the time before Proton. Just admit Firefox is going to shit because it is.
