I had trouble watching video with Safari back in 2006, so back then I switched to Firefox for most browser activity. At that time it was causing Safari to crash.

bf, I found this David Pogue post that puts the blame on Adobe:

^Yeah, it seems to affect OSX FireFox specifically and almost deliberately. It really gets so bad that after a day of viewing (sometimes less) I need to restart otherwise my entire OS slows to a crawl.

Apparently Safari does a decent job of garbage collection for memory leaks, because it doesn't happen when using Safari, but then again I cannot stay logged in.

Flash is so broken these days. It used to be able to use my GPU - not anymore. Now my CPU goes spastic trying to take over, so much so that I had to download a manual fan controller proggy just to keep it from overheating. Oddities, like only certain videos cause the CPU to go nuts (codec related perhaps?), and wild memory leaks. I thought it was Firefox for a while, before getting the same problem in every browser. I miss Macromedia. Fuck Adobe.

Quite possibly found a fix.

From my Safari menu I selected "Reset Safari".

In the Safari Preferences, I went to Security and clicked the button that reads "Show all cookies" and deleted all of them.

Then from my Safari menu I selected "Empty Cache".

Then I "Reset Safari" once again.

This seems to fix the problem. I was experiencing it on two separate computers, so I imagine it had something to do with updating Safari to the latest without completely deleting cookies or whatever... I seriously don't know. Anyhow, no point keeping this around... *discard
