Caillon: could you look at this one and see if this is an exploitable crash?

I can confirm, on linux, that you can focus into the input box even with the
alert open. Can't do much else with the page, but you can hit F5 to reload.

No crash with 1.0.x on RHEL AS4

No crash with 20050707 trunk Firefox ("Deer Park").

Talkback reports of the crash you're seeing might help. Clearing security flag
to get more help possibly reproducing this

Is this still reproducible with Firefox 2.0.0.3 or later using a clean profile?

I can't reproduce the crash with a recent trunk nightly (UA below). Like Dan, I can click the textbox when I shouldn't be able to, however. I'm pretty sure this is a dupe, so not closing, but hoping someone will find the dupe.

This bug was reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.3 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME
