Downloaded the latest Chrome. Extensions are working now, but it still lacks a "LastTab" equivalent.
Despite the synthetic benchmarks showing Chrome twice as fast as Firefox, in practice, I don't notice any real difference in loading e.g. HTF or Facebook. Moreover, Firefox feels faster about half the time.
I should give it time to see if it lacks the Firefox "feature" of consuming 100% of the CPU at times.
(edit in Chrome for behavior check)
