Safari not playing Yahoo! videos
While using safari to browser the internet, it cannot play any video on Yahoo, I tried deleting the adobe Flash setting and safari catched but doesn't seem to work, I had this issue for a while now, and thats the reason why I used chrome most of the time, but since I upgraded to Yosemite, I like safaris new look, and I'm considering on switching back to safari, but is kind of annoying that I can't watch any video, I browser yahoo constantly, so it's kind of a big issue for me.
MacBook Pro (Retina, Mid 2012), OS X Yosemite (10.10)
