If so, any privacy concerns? I'm always bugged by the cookies that various sites throw at a browser. I used to run Firefox with all it's privacy extensions...NoScript, Adblock, Certificate Patrol, Ghostery... But only a few of those extensions are available on Safari, and some block a little "too" much to make a site run properly. Are you guys running just naked Safari 5.1 or with a few extensions only as your main browser? I like the "Lion" features of it...and Firefox just seem kludgy to me now.
