  • re-enable alert on window close at firefox?

    Firefox has a nice new feature: if you have multiple tabs open at the same time and you close the window you get an alert.

    This morning I accidentially deactivated it (unchecked the checkbox).

    How can I enable it again?!

    It must be hidden in the prefs.js but I can't find it
    That's the end of that!

    That's been in Firefox for quite a while actually, suprising you didn't notice it before.

    I have no idea how to get it back though, it doesn't appear to be in the options.

      Well, normally I don't close the window. I have Firefox running with 5-6 open tabs the whole day

      I figured out how to enable it. There was a setting in the prefs.js which was on 'false'. I changed it to 'true' and it's working
      That's the end of that!

        You could also install the "Tabbrowser Preferences" extension and use the options for it to enable or disable this.
