I am talking about on desktop but actually the Android version of Firefox was such a laggy buggy mess I switched to Brave on mobile.
On my desktop I use Arch btw with a 7950X and a 6900 XT. Honestly after using it for over a year I kind of hate it. I am so fed up with how many small annoying problems it has. Someone else mentioned Thorium in this thread and I might give that a try.
If Firefox works great for you that’s awesome but it is BY FAR the buggiest piece of software on my entire computer.
