Safari just doesn't work for me.
It's my favorite browser ui wise, every time i'm getting a new machine i first stick with safari, but after a while under heavy use i notice all the problems with Safari getting slow, doing weird things, etc and i find myself on the Chrome download page again :(
While I was on mac i got an extra few hours of battery life from using safari.
I'm on Firefox these days; with noscript (once you go through the initial few days of pain whitelisting things) it works brilliantly; I would suggest you give it another chance..
Unless you try to book flights from britishairways though.
