just installed it on my n810 yesterday, and I must say, its getting almost fully usable now. Still hangs occasionally, but usually its pretty smooth. Like, really smooth. Like smooooth scrolling through pages and UI elements alike (it looks a little jerky thanks to the lack of hardware graphics support, but its keeping up with your finger). A little disappointed that weave isn't working (http://groups.google.com/group/mozil...3ea8c249502a6b), but with how well tabs and the awesomebar are working, I may just keep this version installed

Also, don't remember if this was added in beta 4 or not, but the application now uses the firefox icon
