@tom-james-watson @benide It seems that this bug occurs because Firefox runs on "Wayland" . So you have to install a "standard" Firefox to run on X11. As said in [1],...

@tom-james-watson Firefox supports log files, and you may run (in terminal) `MOZ_LOG=KeymapWrapperWidgets:3 MOZ_LOG_FILE=/tmp/moz_log.txt firefox` to notify Firefox to write logs about keyboard into `/tmp/moz_log.txt*`. And then please upload it here,...
