I will probably not part ways soon with Firefox because of its vast library of very useful plugins. But Google's Chrome is quickly becoming my essential second browser. There is of course the much publicized feature that every tab in Chrome runs in its own thread, therefore the contents of one tab locking-up do not effect the other tabs.
But Chrome also generally seems to be faster, and I have found at least one huge (for those of us living in bandwidth-starved regions of Asia) Chrome advantage in the https domain: when bandwidth is truly awful and Firefox sits quietly going nowhere for half an hour, Chrome succeeds in bringing down the page, sometimes in just a couple of minutes. The difference between a couple of minutes and a half hour to never is truly vast. No contest. Note that I have not yet tested this for http.
