This happened twice yesterday (never happened before this) -- once while in Firefox and once while closing out of FF and trying to shut down.  Both times there was also strange behavior -- first time a form I opened in FF kept hiccuping and duplicated itself many times; second time I couldn't use pulldown menu for several seconds.  Any ideas?  I'd rather hear it's a software (FF?) issue and not a hardware issue.

    I would run the Apple hardware test, specifically to see if there are any memory or disk hardware issues. When prompted, choose the extended test. It may take an hour + to run, depending on how much memory you have.


    Also, bring up Disk Utility and verify your hard drive. If it finds any issues, you may need to boot to an OS X DVD or external backup to run the Disk Utility repair disk from another boot volume (you can't repair a volume you've booted from).

    While the AHT and Disk Utility (sadly) aren't 100%, passing both says there is not an obvious hardware or disk structure issue. So I'd agree, yes, there likely is a software issue at hand.


    How much free disk space do you have? General rule is to keep 10% of the disk capacity free for systems usage.


    You might want to run OnyX, for it's cleaning and maintenance functions. As with any disk maintenance utility, you should have a hard drive backup before using it (I've used it for years with no issues).  This will clean the system caches, in the event that contributed to what you saw.
