There were a few moments where Firefox seemed to stumble a bit and I did give Chrome a try. Otherwise, Firefox has been my primary browser for ages. Even to the point where I was using a portable version on a locked down computer ages ago. It just works and it respects me as a user.
I daily drive a ThinkPad for work running Wayland. I have one occasional problem with a commercial application that I suspect is related but I haven’t bothered to prove it since it’s so infrequent. Otherwise, rock solid experience for the last year since I was given the machine.
