Firefox >>>> Chrome for me.
Firefox the gawd
Firefox fell off though. They're playing catchup now over there at Mozilla. It's both good and bad the way they're going in my opinion. Everyone's trying to copy chrome and it shows which is what makes it bad in my opinion but it's driving them forward so that's good.

I want that shyt to come back honestly so I can start using the best of the best again but til then, it's Chrome (and Chrome variants) for me.
I was just checking out the mockups last night though. You can tell where they're biting Chrome on the minimalist look and feel but it's done wayyyy better. This shyt would be a godsend.
