Every browser has a problem
I got my first mac last week, a Haswell 15. On windows, I used to use Chrome and I never had a problem with it. With the Mac, I started using safari and everything was cool until I realized that stylish and adblock both didn't work properly. I could go back to using Chrome, but I like the battery savings of safari, not to mention the fact that youtube doesn't get the fans going, but it does in Chrome.
I tried Opera, which solves the problems I had with chrome, but like chrome, doesn't scroll as nicely as safari does.
You guys use anything else? I tried firefox too, and the scrolling is the worst of all there.
