Comment 4 for bug 659309

From original bug report. I have a dump. Can provide with newer one if necessary.

Each time I visit a site we use at my university to give out handouts etc. and
I log out or close the tab that page is being shown in, Firefox crashes.

I don't know how to get a crashdump or any other information about how and why
it crashes. The page is http://fronter.com/uit however you need login
credentials to get in there.

The reason I know it is that plugin is that I uninstalled it to see if that
helped. Firefox didn't crash but each time i went there it complained about me
not being able to chat because I lacked java.

Reproducible: Always

Steps to Reproduce:
1. Go to fronter.com/uit and log in
2. Log out or close that tab
Actual Results:
Firefox crashes

Expected Results:
That tab being closed, or me being logged out

It is also the case on my laptop so it isn't isolated to one machine.
