Firefox will refuse to respond to any user input after a few seconds of opening it. After I try to reopen it, it will give me the "Firefox is already running, but is not responding..." message.

1. Open Firefox.
2. Wait a few seconds. You can do anything in this time. It won't make any difference.

Actual Results:  
Firefox will hang and will not respond to user input.

Expected Results:  
Responded to any user input.

This will only occur under Firefox 4 Beta. It will NOT occur under any other version of Firefox.

so, there are two issues:

1. if you start firefox for the first time, do you really see nothing?

2. when you start firefox again, it will give you a dialog saying it's busy, that dialog should be responsive (it of course isn't particularly helpful, but...)

please have *zero* instances of firefox running (use task manager to ensure this).

please ensure that you install the *32* bit version of windbg and the 32 bit version of firefox. If you do not do this, you'll just waste our time.

please follow the instructions relating to hangs (!analyze -v -hang).

1. No, I see the whole UI, it's just that it will not respond after a few seconds.

2. Yes, that dialog is responsive. 

ALSO: I have tried reproducing this bug, however for some reason it has lengthened the maximum time it will respond for. It can be anyware from the original few seconds to a minute or two.
