When I try to use Firefox in Fedora, it keeps freezing. It often takes 20 to 60 seconds just to switch tabs. I checked about:performance, and when it finally loaded, it didn’t show any obvious sources of trouble. 1840758 - Something keeps freezing Firefox on Fedora Linux
I used my Firefox account to import most of my settings from MacOS, where it works fine. I then switched a few about:config settings to disable animation, since it triggers my migraines. I am not sure what Wayland is, but I also had to change one of its settings to reduce the frame rate to avoid animation. 1771017 - layout.frame_rate > 0 works on wayland/linux only if widget.wayland.vsync.enabled is false
I can’t see a way to install Mozregression or test using it.
