User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:92.0) Gecko/20100101 Firefox/92.0

Steps to reproduce:

1. Install Firefox. Sometimes close Firefox with all open tabs using the "X" button or Alt+F4. Click "Don't ask me every time" because the X button or Alt+F4 won't be accidentally pressed.
2. Work with Firefox, open many tabs. Close some tabs with Ctrl+W.
3. Accidentially press Ctrl+Q while typing in a form.

Actual results:

All tabs, including the current one with the work is gone.

Expected results:

Nothing. Ctrl+Q should not be bound.

"X" and Alt+F4 is sufficient for closing Firefox.
