I like Opera, I can save my progress in sessions. So I might have two browser windows open, each with 15 or so tabs.... just save the session, render or reboot... or whatever I wanted to do, and reopen everything right where I was at when I'm done. It's very slick. I can also copy a web address, right click in a new tab and instead of "paste" there's also a "paste and go" option so it saves a step. It's a great feature that I miss when I fire up FF. There's a lot of neat features actually, I highly recommend it.
