I switched back from chrome to FF few months ago, well I never left really due to firebug and client certs, but now I really don't use chrome anymore. FF is as fast as chrome to start, ie turning off tabs autoloading. I never lost my history with FF while it happened too many times with Chrome. Extensions integration is a lot better in FF, try LastPass for example. FF can have multiple rows of tabs with an extension, I don't think that's possible in Chrome. chrome text search is light years back from FF. And finally, Chrome way of hiding privacy settings, ie delete cookies, is annoying, obviously Google doesn't have any interests on my privacy. FF has been terrible and slow for at least 4 years, but it's back!
