Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode

Please provide a crash id or stacktrace -> https://developer.mozilla.org/en/How_to_get_a_stacktrace_for_a_bug_report

In Safe Mode Firefox crash again. In fact, it hangs, the same that in normal mode. As it hangs, the Mozilla crash reporter doesn't come up or isn't available. I have installed WinDbg. All ok until I try to reproduce the crash or hanging. When I want to enclose a file, the dialog box "Files load" hangs. I can't capture the code, I can't do anything, the WinDbg isn't work then. I have to restart the computer.

The code when firefox is running until the computer hangs is: (1958.16b4): C++ EH exception - code e06d7363 (first chance) (1958.16b4): C++ EH exception - code e06d7363 (first chance) (1958.16b4): C++ EH exception -

By te way... In Ubuntu firefox works ok, without this error.

I've got the solucion... The problem was "Microsoft Silverlight" !!! I've desinstalled this program and now all it's ok !!!
