If javascript can no longer be disabled - how do I leave a website that asks the "are you sure you want to leave this site" pop up question without a yes choice
Given that the turn off javascript option will be disabled - how do I close a page that does not allow me to leave by giving a "are you sure you want to leave" pop up question but then redirects to itself where it again asks that question perpetually?
The only way to kill a page like that sofar was to disable javascript and then close the tab. Now I will have to close the browser - and possibly loose all the tabs I have open.
I want a javascript quick switch - allowing me to easily disable javascript for any page at will. (esp for some of my older, slower netbooks)
Or at least a "FORCE CLOSE" option for malicious webpages.

Noscript may work for this? https://addons.mozilla.org/en-us/firefox/addon/noscript/
The enable JavaScript checkbox will be removed (in Firefox 23?) but I suspect the underlying preference still will be available in about:config, and it may be added to the extensions that provide a UI for advanced preferences.
If pages are abusing the "onbeforeclose" event -- which is the one that asks whether you want to leave -- hopefully someone can come up with a way to solve that globally rather than having users have to come up with a workaround in the moment.
I have this problem and it's driving me crazy. Where and how, in about:config do I make the necessary changes to prevent this highly irritating message from ever appearing? I've searched the entire list of entries in about:config but found none that seemed to come anywhere near related to this "onbeforeclose" thing, the one that asks "are you sure?" whenever I try to exit many (though not all) web pages.
Hi ronc2, there isn't a specific setting for this. Firefox's built-in JavaScript settings allow you to control several aspects of scripts*, but unfortunately not this one.
I previously tried to find some other options for individually turning off this event, but I couldn't find a way. Someone might be able to create an add-on to solve this problem, but it will take someone cleverer than I.
Extensions that disable scripts on a site-specific basis:
- If you regularly visit some sites which do this, you can block JavaScript on that specific site using the YesScript extension. Unfortunately, other script-based functionality will be blocked as well.
- YesScript does not preemptively block scripts on every site. If you have to visit a lot of random sites and want to take a paranoid approach of having scripting blocked until you see as much of the site as you can see without running scripts, then the NoScript extension would be for you. But even then it's "all or nothing".
