I downloaded a .torrent, and it opened in uTorrent, like it is supposed to.  At this point Firefox was no longer the active window.  I was doing nothing at all with Firefox when the error happened.  It closed Firefox.  I had just (within 5 seconds) completed a download.

Reproducible: Couldn't Reproduce

Steps to Reproduce:
I really don't know how to reproduce the error, I've downloaded .torrent's before, never seeing this error.
Actual Results:  
Firefox crashed

Expected Results:  
I didn't expect anything to be going on with Firefox at the time of the error

A few other people have received the same error, but none in the same situation that I found it.  It seems like none of the reports have been fixed or confirmed.
I am using the default theme.

when you get the dialog, instead of dismissing it, attach windbg, setup symbols (per the above url) and then enter:

~* kp

*attach* the output from that command here.

It happened to me as well downloading .torrent file. The only difference is thatmy firefox is not setup to open uTorrent when downloading a .torrent file. It simply downloads the file to a certain prior determined folder c:\Downloads

When the error came up, my computer had many processes running at the same time as well downloading a .torrent in Firefox. see attached screenshot.

This has also happened to me numerous times since upgrading from to (I refuse to upgrade to v.3 until Bug 438830 is fixed). Not when downloading any files, but when loading a new page, usually when surfing various forums. No particular rhyme or reason to the crash, but it happens several times a day for me and is incredibly annoying. (see Attachment #350912 [details])

I keep getting this error (R6025 Pure virtual function call) since running Firefox 3. I think it has something to do with flash. The pages that it randomly crashed on always has a flash banner. I have upgraded and re-installed flash and still the same error. This is windows XP 32 bit running 3.0.11 Firefox. Whats odd is I can still use the browser even while the error is up.

eric: please read comment 1 carefully.
I get this error when I open the following URL:

If I don't click "Ok" in the message box where the error is shown, I can still use the browser (all opened windows and tabs). However, if I click "Ok", Firefox closes all its windows.
A few things:

- It is likely this error is triggered via external software integrating with firefox (like plugins).

- Not everyone hitting this error message is necessarily hitting the same bug. The error message is pretty generic: different people may be triggering it in completely different ways.

So if you want this fixed we really need *you* to follow the steps from comment #1 (on the page ) and attach the results. Even if you found a site or list of steps that often triggered the error it is likely others could load it without ever crashing unless they have the same versions of the same extensions and plugins you do. And waiting for someone else on this bug to do this will not necessarily help getting your problem fixed.

Getting windbg set up is initially a bit of a hassle. If the instructions are hard to follow or do not work please say so. Or if you can connect to irc:// you can poke me (mzz) there and I'll try to help.
Reporter, are you still seeing this issue with Firefox 3.6.x or later in safe mode? If not, please close. These links can help you in your testing.
