Thanks guys. I went back because I was trying to avoid the flash player blocking which is a PITA but the blocking seems to be retroactive
36.0.4 is only four months old. not exactly Flock (out of insane curiosity I am going to temporarily load Flock and see if the site runs)
(update, just tried, Flock doesn't even open)
But Alex S is right, It is almost certainly something picked up looking at Charlotte McKinney pictures
