I've been using Google Chrome, actually. It looks very clean and runs pretty fast, at least comparable to Firefox, which was my prior browser of choice, mostly for security and tabbed browsing, which Firefox has had for a very long time, and is still is not very good in IE.
I do, however, use IE for Netflix instant viewing, and at work and school. I really don't like it. It's like they tried to integrate just about every feature the others tout, but each feature feels separate from the actual browser. It doesn't feel complete or seamless at all. Chrome, however, feels very seamless. I recommend it, because you're having trouble with Firefox. I started using Chrome for that very reason and haven't found anything I don't like yet.
EDIT: I also like the "New Tab" screen in Chrome, because it has thumbnail pictures of the eight or so (but I think the number is customizable) last websites you typed into the address bar. In fact, most of the time I open Chrome, hit new tab, and close the first one. I don't visit that many websites, so all the ones I like are all right there with no typing required.
IT'S ALL ABOUT SPEED, BABY!
