If you’re like us, it’s easy to have 20 Mozilla Firefox windows full of hundreds of open tabs at once. Fortunately, there is an easy way to close multiple Firefox windows at the same time. Here’s how to do it on Windows, Linux and Mac.
So you̵
To close all Firefox windows on Windows or Linux at once, click the hamburger button (three horizontal lines) in the top right corner of any window. Select ‘Shut Down’ from the menu that appears.
You can also press Ctrl + Shift + Q on your keyboard.
To close all Firefox windows at once on a Mac, click the “Firefox” menu in the menu bar at the top of the screen and select “Close Firefox”.
You can also press Command + Q on your keyboard.
By default, a popup will appear warning you that you are about to close a large number of tabs at once (unless you have previously disabled this). Click on ‘Close Tabs’.
After that, you will quickly see all your Firefox windows disappear one by one. To get them back, restart Firefox and select “Restore Previous Session” from the Firefox menu.
Info: If you’ve previously configured Firefox to always open in private browsing mode, the “Restore previous session” option will be greyed out.
After that, all the Firefox windows you just closed will reappear. If you prefer to reopen them one at a time, the windows and tabs you closed will be displayed in your history (unless you’ve set Firefox to clear history after closing). Have fun browsing!
