Status: VERIFIED FIXED

(Core :: General, defect)

Description

[Carsten Book [:Tomcat]]

Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9b4pre) Gecko/2008020621 Firefox/3.0b4pre

Note, its the same assertion as in Bug 414808 but this is on different scenario

Steps to reproduce:
- New Firefox Profile
- Install the Session Saver Extension (this make it easier to reproduce this problem, but its not necessary) https://addons.mozilla.org/en-US/firefox/addon/2324
- go to http://www.popuptest.com/popuptest12.html
- the popup warning bar is displazed, choose "allow pop-ups for www.popuptest.com
- Reload the Site
- the 3 popup sites are displayed
 -Quit Firefox with this 3 pop up windows open

Firefox does not close and instead you get a lot of error messages and a assertion:

###!!! ASSERTION: Oops!  You're asking for a weak reference to an object that doesn't support that.: 'factoryPtr', file nsWeakReference.cpp, line 109

Note, the problem in general here is causing also bug 416048.

note: the same assertion comes also up when a extension is downloaded/installed with the Extension Manager.

Tomcat, can you get a stack for this assertion?

done :)

this stack is from the case when i install a extension with the extension manager (like going to addons.mozilla.org , choose a extension and click on install now and on "install") with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b4pre) Gecko/2008021917 Minefield/3.0b4pre

Bummer, the stack is all JS. This definitely looks like a bug in the extension. Would be excellent with a JS stack. Ping me on irc and I can help you create one.
