Ever since I installed Firefox, I get this message 9 out of 10 times when I try to shut down or restarting the computer:
When the "ending program" meter goes full, it says, "______ couldn't be shut down properly", then I click "End Now". Then I do the same thing again 5 times, then the PC finally shuts down.
It doesn't do that when I try to go "Stand by". I have never seen this before I installed Firefox. A few weeks ago, I upgraded from 1.0.7 to 1.5, but it still does the same thing, except that "firefox.exe" appears as much as "XPCOM:EventReceiver".
This happens 9 out of 10 times to me, and it's really making me mad.
Any suggestions on what I should do?
