I had this .NEF file (Nikon raw photo) and I don't have any plugin or extension for handling this file type. This file is basically a 5MB blob of binary data. I dragged it onto an empty FF3 tab anyway to see what it would say and then it crashed. Since I have win2k breakpad isn't supported but I got MSVS2005 installed so I selected break into debugger and I saved a mini dump (which I will attach to this bug shortly).

When I try to repro this bug is doesn't crash again, instead I see a dialog asking me to open or save (which is expected).

The call stack for the crash started in firefox.exe and had then called into zul.dll so my theory is that I accidently triggered some very obscure condition that caused FF to crash during the creation of the open/save dialog UI.

Oh, and one more thing. The first time I started FF3 after the crash then it said "installing" updates, so this could potentially be a 100% reproducible crash. I will go back and try a few older builds to see if this is the case. If I find something useful I will post it here.

well it might be complicated bug. What I got is that something may have changed that caused Firefox to crash (E.G. you were using an older build and Firefox was set to update to the newest and then before you restarted you dragged a file).

Does it happen if you grab an older build and then go to help check for updates and then restart firefox later and drag the file then. 

If it doesn't then it might have just been a random hiccup in your OS or in Firefox. Sometimes that happens with computers they aren't perfect.

But if it continues we want to know, others may be experiencing similar problems.

Thanks,
