I have set various custom shortcuts for all apps on my mac in System Preferences > Keyboard > Shortcuts > App Shortcuts. These are:

  • Ctrl + Opt + Left Arrow - Move Window to Left Side of Screen
  • Ctrl + Opt + Right Arrow - Move Window to Right Side of Screen
  • Ctrl + Opt + Up Arrow - Zoom
  • Ctrl + Opt + Down - Move to Built-in Retina Display

These shortcuts work for all other applications on my mac (Catalina 10.15.4), but not with Firefox (version 76.0.1). On the Maximise window where these options reside via mouse, the shortcuts do show up, and pressing the options with a mouse does work, but the shortcuts do not.

If this is consistently the case, I'd look at posting a bug on bugzilla. https://bugzilla.mozilla.org/home
