Hi, i bought about a month ago the new MBPR and i found out that the safari browser is better than chrome for my needs. Before i buy my new laptop i was a google chrome user on the windows platform and i installed the adblock extension. So i had no ads. Now on safari i also installed the adblock extension but the youtube ads are still there. The ads from other websites are blocked. Is there any way to block the ads from youtube using safari? I would really appreciate your help here.
