Just had my Minefield nightly build go totally unresponsive while being in a different app. It started using 200% CPU, and was entirely frozen, but didn't crash. I waited for quite a while, but it never returned, so I did a sample using Activity Monitor (attached). I then had to Force Quit it. The OS didn't recognize it as frozen — there was no Force Quit menu item in the dock, only Quit (which didn't do anything). I had to use Activity Monitor to Force Quit the process. Open tabs included Gmail x 3, Etherpad, Bugzilla, some screenshots in JPEG format.
No crash report was generated, for the record.
OK to close this issue?
