I noticed something the other day about Safari 5, There apparently is a new update available! 5.0.1 to be exact. And the best part is that it seems that this update has fixed the high memory usage, hurray!!  So if you are having trouble with high memory usage in Safari 5, just update it! I’m not making any promises though, this is what I have experienced, your result might be different. Anyway, it’s nice to see that my favorite browser on Mac is finally working as it should again.
