Upgraded 2 the 6.0 & ever since whenever I open a new tab I have to sign in all over again 2 my social media sites DIGG, Twitter, StumbleUpon using my AddThis addon What's Up? never had to do that before when activating additional tabs once I was signed on 2 those sites that was it. Its even happening now with some news sites if I sign on 2 a news site in one tab then open another I have to sign on again 2 that same site.. HUH. Even having issues with AddThis freezing up..
