Close tab warnings
Firefox can be set to warn you when you’re about to close a window or quitexit Firefox, when multiple tabs are open. You will then have to click a button to confirm your action.
There are a few different ways to close a Firefox window or quitexit the browser. Starting in Firefox version 94, Firefox no longer warns you by default when you quitexit the browser or close a window using a menu, button, or three-key command. The close actions in these particular contexts were likely intentional and so the messages provided unnecessary and perhaps unwelcome interruption.
The only instance in which a close warning is on by default is for two-key quit shortcuts on macOS and Linux. The risk of accidental closure is higher in this context since the quit shortcut (⌘+Q) is adjacent to the switch-application shortcut (⌘+Tab).
Despite these changes to the default action, you will still have full control over the quitexit/close modal behavior. All warnings can be managed within Firefox Settings .
