I have a Inspiron 15z, and for the past week or so, I have been getting frequent error messages when using Firefox. I'm currently on version 30.0 (beta) but had the problem with the regular FF also. It seems to happen most often when the computer has been idle for awhile or when waking from Sleep. My 2 other computers have had no similar issues with FF.

FF "recovers" my tabs when I reopen it after a "crash", but this is getting frustrating. Any ideas?
