Posting from Safari here too.
I must say I really like it, save for a few things. No status bar at the bottom
no more mousing over links to find out where they go, I guess? Also, no extensions (obviously) means no more FoxyTunes, Weather, etc. Just a nice convenience I'd gotten used to.
I'll probably end up going back to the ol' Fox for main web browsing, but the speedy and aesthetically appealing Safari works well for quick jogs (a quick email check or something), since my way-too-extensioned-out FF takes a bit to load.
