It simply shows a 'waiting' cursor and hangs. Force-kill the task to close it. Reproducible: Always Steps to Reproduce: 1. Go on File -> Open File... 2. Open a folder where a file can be seen 3. Right-Click the file to open a context menu Actual Results: Firefox hangs. Expected Results: Showed Windows file context-menu. Windows is Build 7100. Does seems to happens on RC and OEM softwares I tested as well.
I too experience this problem, making Firefox completely unusable (I use Chrome now). I cannot get a stacktrace with WinDbg since the hang won't occur. I should add that when it hangs, Firefox consumes no CPU, so I'm guessing it's some kind of deadlock issue, which is probably why I can't duplicate the bug with a debugger attached.
you can attach to firefox w/ windbg instead of running firefox from windbg. use file>attach to process or such. the instructions are mostly the same otherwise.
looks like op is not here around, if you can reproduce, feel free to reopen it!
