Safari Youtube = System freeze
Hello all! I have the most recent version of safari 9.1, and I have noticed that some times when I'll be browsing youtube watching videos my system will freeze. Once it freezes all I can do is forcibly turn off my macbook and restart the computer. Does anyone have any ideas how to solve this issue? It's starting to be become more frequent and it's annoying.
MacBook Pro, Mac OS X (10.4.11)
