When visiting the Pittsburgh Penguins website (http://penguins.nhl.com/ within 10 seconds WebKit crashes. All other sites visited since downloading r39474 have been fine. I do get the "Extensions detected" pop up as I am using Safari AdBlock but have never had a problem with it before.......Jack
Please try un-installing AdBlock, and also please attach a crash report. I'm not getting a crash on this page with a local debug build of r39509, so I suspect an AdBlock bug. Closing as INVALID for now, please feel free to re-open is this keeps crashing for you without extensions.
