Doesn't work on linux. you say to read the description if you're on linux but there's nothing there

Works great on Windows!

Does not seem to be working at all on Ubuntu

Doesn't work on Linux.

Works great, WIndows 10

Does work on my Firefox 73.0.1 on MacOS Catlina.

Does not work on Ubuntu.

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.

Doesn't work. Ctrl-q still quits Firefox 62.0.2.

Worked great until Mozilla changed the panic-quit command from Ctrl+Q to Ctrl+Shift+Q, which I've accidentally mashed, so this extension no longer does anything. (Experienced in Firefox 62.0.2, Windows 7, 64-bit.)

it doesn't work

Works flawlessly on MacOS.
Would you mind publishing the source code? A GitHub repo would be great.

Doesn't work on Ubuntu!

doesnt work

STILL does not work on Linux.

It doesn't work. At all.

I'm giving 3 start because I didn't read that this doesn't work on linux.

Note for other Linux users: Most DEs use control q as a universal keybind. Unbind it first.

Does not work (Firefox 61.0.1 on Linux).
