I use Top Sites all the time, multiple times a day and I rely on the star to let me know when one of the sites has new content. Ever since upgrading to Mountain Lion the top sites page does not show a star on updated sites. The thumbnails refresh, and I can make changes to the top sites and the order of the sites, but no star appears to indicate updated content. I've removed the top sites plist file, reset Safari completely, re-installed it, and tried just about everything else I can think of. I can't stand Chrome or FireFox, but if this feature won't work in Safari 6, I can't use it anymore.... Anyone else having this issue? Know of a fix besides resetting the top sites and Safari preferences? Thanks!
