What is the fastest browser for a Mac laptop, but has good graphics too?
I would suggest firefox
Chrome's pretty awesome, that's for sure, but if ever liked Firefox now's the time to try it again. Firefox 4 is really awesome, and feels much faster on my Mac than Chrome or Safari. Great graphics support, too, which you can test out with the Web O' Wonders.
Personally I would go with Google Chrome
Firefox always felt a bit bloated on OSX [for me] and I've never been a friend of Safari. I used to like Opera but it's so (over)loaded with features - not that it's slow or something, I just prefer things more simple.
There are other options too, like Camino, Shiira or iCab but I haven't used them for over a year now.
The best way is to try them out yourself.
You can find a lot of options at the following links
Another vote for Chrome!
