There is now an extension just for that:

For those who are interested in using this plugin, it is restartless. – Can't Tell Dec 14 '14 at 4:14

You should obtain a similar result, easier, enabling the hidden config option (about:config).

  1. In Firefox's address bar, type about:config and accept the warning that it will give. Now it appears in front of you a long list of config options. Filter it typing the keyword quit in the filter bar (up top). After that the filter acts you will have only few lines. Click on browser.showQuitWarning and set it true by clicking on it.

  2. You can use this filter again with the keyword warnon and see if the options "warn when close tabs" and similar are set to true.

  3. In the Firefox's Options/Preferences (or Edit/preferences it depends from system and version), go to the Tabs section and check the option "Warn me when closing multiple tabs". This will prevent you to close a window with multiple tab.

You will not completely disable CTRL-Q but at least you will make it harmless.

Unfortunately, for me (on Ubuntu 14.10 with Firefox 33.0), setting the key "browser.showQuitWarning" to "true" does absolutely nothing. :-( So I had to install the above mentioned extension just to disable keyboard shortcut. What a world we live in. – okolnost Nov 22 '14 at 13:43
It just worked for me with 14.04. – arhuaco Jun 4 '15 at 16:22

I could not get it working. Could you please list the exact steps to be followed? – 3l4ng Jul 5 '15 at 18:02

Bear in mind that not all actions can be customized without an extension.

I use keyconfig to move into tabs prev/next by using ,/.
