A rich application we are developing creates and destroys the codeMirror javascript code editor. After a few cycles thi crashes FF. I've extracted the offending code and put it in the page linked to this bug report. Simply press the button on that page several times to crash Firefox. Note that it sometimes takes a lot of clicks while other times it happens after only a few clicks.

Getting a don't hotlink message when opening test url - not sure if that is why I am not getting a crash. Tested ~100 clicks.

Can you provide a crash id (about:crashes) and/or stacktrace? https://developer.mozilla.org/en/How_to_get_a_stacktrace_for_a_bug_report

I've fixed the problem that was causing the hotlink error. 

Retrying the crash page after fixing that problem I only had to click 3 times to crash FF.

this was fixed about two days after the build you used.
