I had been using Dolphin HD for awhile, but just tried Opera mobile and it's pretty damn good, way better than Dolphin IMO. I like how you can make flash videos an on-demand thing similar to Dolphin so they don't slow browsing. The interface is very clean. And it's quite fast, even on my now rather dated Galaxy S. I'm not normally a fan of Opera, but it's the best Android browser I've tried. Mobile Firefox is a disaster. The stock browser is getting quite dated and it's slow. I'm surprised Google hasn't attempted a Chrome port. Any other browsers you guys have tried or opinions on which one is best?
