How to Disable Firefox's Emoji Picker
Annoyingly enough, Mozilla decided to add a emoji picker to Firefox 150, which fair enough, probably some people like, but they did it by using the shortcut of Ctrl + . (Control + Dot), which also happens to be the exact same shortcut 1Password uses by default, and has been using for as long as I can remember!
On GNOME we already have a global shortcut for some emoji picker, I think it's Super + , or something, and besides, I don't really write any emojis in anything I use a browser for anyways, so off we go to disable it so we can properly use 1Password again.
How to disable the shortcut
Easy peasy:
Open about:config in Firefox Search for widget.gtk.native-emoji-dialog Set it to false Restart Firefox if Ctrl + . does not immediately work
For me it worked without restarting, YMMV
