Question

I have a firefox extension that listens when the firefox has launched using

observe: function(subject, topic, data)
{
if(topic == "app-startup")
{

}

similarly how to listen the firefox quit/restart event using javascript.

Please help.

Answer 1

Register to observe quit-application-requested (self-explanatory) or quit-application (the app is about to quit, either in response to a shutdown or a restart).

You can find a big list of observer topics on this page:

Note: As of Firefox 4 you should no longer be using app-startup to register a startup notification. Use profile-after-change instead.
