Thank you for the extension. Works well on macOS Catalina.

Works as described. MacOS Catalina + Firefox 76.

Works great on Windows!

Works great, WIndows 10

Does work on my Firefox 73.0.1 on MacOS Catlina.

Thank you. What a stupid shortcut that is.

Works on Windows 10 with Firefox 66.0.2.

Absolute essential Add-on ! Works perfectly reliable !

Works as expected on macOS, the shortcut no longer quits Firefox.
On GNU/Linux it doens't work as stated in the description, until upstream adds the necessary APIs.

Best. Add-on. Ever. It's as simple as that. Windows 10 user.

This extension saved my life. An essential download; cmd-q and cmd-w are just one key away from disaster!

Works perfectly on Windows and OS X, but sadly doesn't work on Linux. However, this is clearly stated in the description, so no false promises - thus 5 stars.

Excellent add on. Not sure why this still isn't a feature! Really appreciate Rob W making this.

Please add a note to the TITLE saying that it DOESN'T work on Linux.

Man, I was so sick of accidentally quitting Firefox and having to wait for it to reopen a zillion tabs gain. This extension is wonderful.

Simply works as described. Thanks!

It works well on macOS High Sierra.

WebExtension, does exactly what it says on the box. Works perfectly on Firefox Quantum on OS X 10.12
