  • Simply works as described. Thanks!
  • It works well on macOS High Sierra.
  • Does not work on linux (as of 2017-11-21 in Firefox 57).
  • Does not work in Firefox 57. I'm using Ubuntu 14.04 LTS.
  • WebExtension, does exactly what it says on the box. Works perfectly on Firefox Quantum on OS X 10.12
  • Works like a charm on Windows 10 (1703)
    Thanks for the confirmation. You are the second to confirm that it works on WIndows 10. So it seems that the add-on works fine on macOS and Windows, but not on Linux.
  • Doesn't seem to work any more with new Firefox 57 :-(

    Sorry, I don't know how to reply here, so I hope you see my edit: I am using Ubuntu 16.04. The plugin loads, but Ctrl+Q still closes the browser. Let me know if you need more info and thanks for any help!
    Which OS are you using?
  • I can confirm that this doesn't work at all under firefox 57 and linux ubuntu 17.10. I don't give a one star because it works elsewhere :-) I'm sure that the developer will fix this. Thanks for your work, and I hope for a fix in linux.
  • I never knew I needed this. It works. It's great.
  • Works great on Windows 10!
  • Works perfectly for most use cases and is a life saver!

    Obscure bug: If the history/bookmarks window is open pressing Cmd+Q closes all windows. It's a pretty rare case though.
  • this is just what I needed, works fine in FF Dev Edition on OSX Sierra
  • The low ratings are unwarranted. This add-on is functional on macOS and the only one that works with Firefox Developer Edition (or Firefox version 57+). Thanks, Rob W!

    The problems on Linux are unfortunate (I use Linux too), but are caused by Firefox and not the extension author's fault.
    Thanks for this review. Although 1-star ratings are not ideal, they are deserved until the add-on also works for everyone.

    Could you also write which OS you're using? I know that it works on macOS, and not on Linux, but I'm not sure about others.
  • it just does not work
  • Thanks for trying, though.
  • Ctrl+Q still quits on Linux.
  • Works well on OS X. Might be nicer if instead of simply disabling Cmd+Q it popped up a warning which then allowed pressing Cmd+Q a second time within a couple of seconds to actually quit.
  • Excellent addon, but needs a GitHub repository or similar to manage issues (reviews are not really a good place...)
    The code behind this add-on is so simple* that I haven't bothered with creating a Github repository.

    To get support, just mail me (see "Support E-mail" at the add-on listing for my address).

  • Please fix this
  • Does not work in my case.

    Arch Linux x86_64
    Firefox 52.0.2
    Confirmed, sorry for that, I hope that you did not accidentally lose your tabs. I have edited the add-on description to state that it does not work on Linux for now until https://bugzilla.mozilla.org/show_bug.cgi?id=1325692 is fixed.

    For now, you can use https://addons.mozilla.org/en-US/firefox/addon/disable-ctrl-q-shortcut/. That add-on will cease to work by the end of this year though. Hopefully the linked bugzilla issue will be fixed by then, so you can install this add-on again to get it to work (or keep the add-on installed; although it does not work right now, it does no harm either).

    If you want to manually prevent the Ctrl-Q shortcut from working, open the global JavaScript console (Ctrl-Shift-J) and run the following code. This needs to be done for every new window.
    document.getElementById('key_quitApplication').remove()
  • Does the WebExtensions API make it possible to implement a CMD-Q Catcher-like behavior - e.g. press Cmd+Q twice to quit?

    EDIT (reply): I use it in Opera (which has it in its advanced options: Hold Command-Q (or press it twice) to quit Opera) and like it very much. That's why I'd like to have it here as well to keep the behavior consistent. CMD-Q Catcher does just that, but it's an old and unmaintained extension without the e10s support.
    The add-on just overrides Ctrl-Q and ignores the keystroke. I don't know if there is a way to exxplicitly quit Firefox (I can close all open windows, but I don't know for sure whether the windows would be restored when Firefox starts again).

    I believe that quitting is such a rare operation that it should not be possible to do it by accident. Two Cmd-Q presses can still be done by accident.

    If you want to explicitly quit Firefox by keyboard, you can use the following shortcut:

    - Linux (and Windows too, I guess): Alt + F, Q
    - macOS: Fn + Ctrl + F2, Arrow right, Arrow Down, Q, Enter (Ctrl instead of Fn + Ctrl if you are not using a Mac keyboard; to enable Ctrl+F2 the menubar shortcut should be enabled, see https://superuser.com/questions/303525/what-is-the-shortcut-to-access-the-menubar-in-mac-os-x).

    (by following these shortcuts, you are basically opening the menu and activating the Quit menu item)
