I feel the pain. Unfortunately I gave up trying to get Firefox to understand/use super or hyper as command keys. Mostly however I get by fine with caps lock set as control with the exception of VSCode with the Vim plug-in overriding ctrl-c/ctrl-v and breaking copy/paste. Of course VSCode doesn't support super/hyper instead of control key on Linux.
