Firefox has improved in that regard too. I remember I couldn't do one-word searches on the address bar at one point, but now it works. Chrome is good too, but I prefer the layout of Firefox (maybe because that's what I'm used to).
I don't hate firefox, or any browser infact, I just recommend others because of what I know, I've only used a handful of browsers in my life after all. I haven't tried every one yet, maybe there's an even better web browser for low end PCs than Opera.
