I was away from my Windows 10 computer and when I came back Firefox was gone and replaced by a notice that it had crashed and would need to restart. Restart could not proceed because Firefox was still running. I went to the Task Manager to end the Firefox process but the Task Manager was not able to stop it. I had to reboot the computer to end Firefox. You know a crash is real bad when the OS can't even terminate it. Just wanted to see if someone could pass this along to the developers as the feedback page does not appear to be working. Thanks
