It seems a joke but is also, sadly, a fact. Chrome bookmarks manager is lightspeed if compared to Firefox, to not mention total lack of usability on Firefox's part, so 1995.
I was against them writing significant portions of Firefox in Javascript from the beginning. Maybe a generator from JS to native for templating interfaces or something. I could see some compromise to aid the web crowd in extending Firefox. Shouldn't be what's running, though, given the inefficiency.
