It's odd that people seem to feel like Mobile firefox is so slow. I find that it takes a bit longer to load initially, but doesn't take any longer to actually display full pages than microB. I feel like it scrolls pages better than MicroB and that its double tap zooming is a great feature as well as the text entry. It's a bit annoying to have to scroll all the way to the top of a page to access forward/backward/and enter a new url, but this isn't too bad considering half the time I was clicking the wrong thing in microB and then I'd have to wait for it to reload a whole new page I never meant for it to go to. In the end, it will need some tweaking, but it's a great start.
