Is it fixed?
The answer to the previous post's title is "NO!"

Firefox keeps crashing on me! When I first downloaded it back in January 2005 Firefox was supposed to be infinitely better than Internet Explorer, and much more crash-resistant. Sadly, that is not the case. Maybe it's just the usual heat-related problems with my PC (although the room temperature is still below 78), maybe it's the increasingly complicated moving adds that infest most websites and kill my PC's performance.
Meanwhile, Firefox says that I have all the latest updates, so it's not that

But whatever the cause, the symptom is that Firefox is collapsing faster than George H.W. Bush at a state dinner with the Japanese Prime Minister! Grrr!
