OWB still works fine, but without updates it will be a matter of time before it will start to feel outdated. And I would be very surprised if Fab isn't on the case already.

Problem today isn't so much the browser, but all the recent CPU intensive bloat you see everywhere, making browsing on MorphOS less enjoyable. And this is probably just going to get worse unless we get multicore support. Or bloat becomes a fad like animated gifs was.
