Keyboard shortcuts to open containers conflict with Firefox's own shortcuts and with macOS's in some keyboard layouts

[AlphaHydrae]

Actual behavior

On macOS with a Swiss keyboard layout:

Cmd-Shift-1: container 1 opens, zoom increases (due to Shift-1 being the Plus (+) character in this keyboard layout, so Cmd-Shift-1 is also Cmd-+, Firefox's own shortcut to zoom in).
Cmd-Shift-3: no container opens, macOS starts a screen capture
Cmd-Shift-4: no container opens, macOS starts a screen capture

Expected behavior

I'm not expecting Firefox to have conflicting shortcuts, or to override the macOS shortcuts so I guess I would either expect containers not to use any existing shortcuts, and/or even better, to be able to customize them.

Steps to reproduce

Attempt to open containers 1, 3 or 4 on macOS with the keyboard shortcuts (Cmd-Shift-N) on macOS with a Swiss keyboard layout.

Notes

Firefox: 80.0.1 (64bit)
macOS: 10.14.6
Keyboard layout: Swiss French

Whoops, sorry I did not look hard enough. I only just now found the way to change the shortcuts.

For anyone who might find this issue: Go to Add-ons > Gear Icon > Manage Extension Shortcuts

Yes, you can choose a container to correspond with a selected number, but that doesn't change the fact that Cmd-Shift-3, 4, and 5 still run into conflicts with macOS. This still needs to be fixed. Perhaps instead of using Shift, the Option key should instead be used.
