Works well on X. Maybe SDDM 0.19 will bring some improvements during login/logout (already built for f34), at least before Systemd Startup is available https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/47
@dimitrisk more likely RC 2 http://ftp.mozilla.org/pub/firefox/candidates/82.0-candidates/
In general, taking into account going through testing and propagating mirrors, Fedora users often get new Firefox after many others. It seems reasonable to keep last RC in testing and, if it works fine, push it in time to hit stable repositories on official release.
