...so the bug should still be titled: "Firefox unusable on Kubuntu 21.04 Wayland session" as it was originally, as it may not be the exact same upstream issue.

Firefox is practically unusable since it refreshes the screen only on re-focusing like described in this bug report: https://bugzilla.mozilla.org/show_bug.cgi?id=1616894 Unfortunately, setting widget.wayland_vsync.enabled to false does not make any difference. Also tried starting firefox from terminal with MOZ_ENABLE_WAYLAND=1, again no difference. According to the above bug report this should be fixed, no?
