"I notice that the browser AlwaysInnovating talk about is Mozilla Fennec"
Looking at a review on this. It certainly sounds promising. However, as always it requires a single person or small RISC OS coding team to actually do the port and make it fully functional under RISC OS.
Personally I would like to see the RISC OS port of FireFox 2 brought it's conclusion rather than begin porting yet another web browser, no matter how tempting it maybe.
