Thank you Jon for uploading this report.

Could you describe how did it happen? If it is reproducible, please indicate step by step how to do it so we can have a test case.

[Jon Leighton (jonleighton)]

It's not really reproducible. I have been experiencing several Firefox crashes recently so it's hard to pinpoint what caused it, but I think this one may be related to the Firebug extension as I think I experienced less crashes when I disabled the extension.

I have Firefox set to always keep the tab bar visible, and when I have only one tag open and want to get rid of it (and therefore go to my home page of about:blank) I will middle click it. This is what I did and the browser froze and then eventually crashed.

[Alexander Sack (asac)]

should be fixed upstream. and we haven't received any dupes for quite some time. closing.
