I loaded Firefox up with Adblock and a few other things and it crashed so often I stopped using it. Even after I tried removing all that, it still ran like shit. I switched to Safari and haven't had many problems with it. It does have a bad habit of crashing when I first turn my computer on, but waiting until everything is running usually solves that problem.
See, here's another thing.
I've had no problems, no problems at all, since TVDOC set up this computer for me little more than a year and a half ago.
If he were to see it today, he'd recognize it all immediately, because it's still set up exactly the way he set it up.
This is the longest time I've ever gone with a crash or some other malfunction.
I could be wrong, but I credit it to the fact that I don't ever "add" anything to it; it seems to me the more working parts something has, the more likely it is something's going to break down.
Also, since I don't--for obvious reasons--do movies or youtubes or whatever on it, I wonder if that's an additional factor for the computer to always be running so well.
