I think I will be giving Chrome a try
FYI you're not going to find as many extensions (there is still A LOT), but you can install Greasemonkey scripts userscripts.org. It's not light years ahead f Firefox, but has some nice features, is minimalistic, and refreshing.
Benefits over Firefox:
Plugin crashes like flash, crash where the flash (or other plugin) actually lie. If a Youtube video crashes you'll see it only where the video is and the browser won't crash.
