Thanks for the report! This is likely Gnome Xwayland bug (bug 1788205) and should be fixed by https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2970. Please test if this problem can be avoided by starting Firefox with this command: `$ MOZ_ENABLE_WAYLAND=1 snap run firefox` To use MOZ_ENABLE_WAYLAND=1 by default, you can either: a) Switch to Firefox Nightly which already uses MOZ_ENABLE_WAYLAND=1 by default (bug 1543600): `sudo snap refresh --channel=edge firefox` b) Add `export MOZ_ENABLE_WAYLAND=1` to the end of /home/yourusername/.profile to set it permanently for your user account. `$ echo -e "\nexport MOZ_ENABLE_WAYLAND=1" >> ~/.profile` It takes effect after logout&login or a reboot.
