I’ve been using Firefox 3 (beta5) pre-release lately, because it’s faster than Firefox 2.
Generally I don’t like their “session management” (browser.sessionstore.resume_from_crash false). It would be good if I could simply ‘lock’ certain tabs like Gmail, which really must be my first tab. I also want it locked so I can’t accidentally navigate away from it which I have done far too many times now.
I am most impressed by the improved “feel” or responsiveness of FF3. I really hope Mozilla can concentrate on re-factoring their code to squeeze it into their ‘fennec’ mobile browser. Update: Blassey kindley informs me Fennec and FF3 are the same rendering engine.
Actually, when I think about it, an addon could be called a widget.
