I want to change my open shortcut to CTRL+SHIFT+X so the shortcut is the same as on Chrome. That particular shortcut is used within firefox and I couldn't find a way to disable using 'about:config'. It seems that the 1password plugin doesn't override it when I set the shortcut. Pressing CTRL+SHIFT+X will still do the default firefox shortcut instead of opening the 1password box.
It only works if I set the open shortcut to be some combination that is not in use, like CTRL+SHIRT+Q.
1password Version is 1.22.3. Firefox version is 84.0.2. I'm on Ubuntu so I rather stick with the extension over the standalone app.
