safari freezes and beach ball appears
hello, i recently did a erase and clean install of OSX ML. everything seems well until i was using safari and opened a website as well as a new TAB with youtube on that new tab. after a couple of minutes of using safari having the two tabs open, the beach ball appears and safari freezes. one of the two tabs that has a site the page becomes white blank. Ive reset safari, repaired disk permission, deleted the cache file in safari folder, even reset PRAM. Don't know what else to do. don't know if it when i visit the youtube page or something else. i have a 2009 MBP which i use the exact same way and it never freezes. Safari version is 6.2.8 on both my 2009 macbook pro and the one that freezes is 2012 MBP non retina 15inch. any help would be greatly appreciated. THANKS
