problem with safari and adblock

Hey Guys!

Finally I became a Mac User.
I dont use Windows anymore, but now I got some.. "problems".

For example I used Firefox on my Windows system, now I use Safari.
If I watch a stream on www.twitch.tv I still get ads and promotion clips in the breaks from the streamer. Of cause I use adblock from Safari!
With Firefox and Firefox adblock I dont get ads and promotion clips on www.twitch.tv.
I stopped using Firefox on my Mac, because Firefox crashed my System multiple times.
First firefox stopped and I cant turn off the system, because Firefox cant close, and after that my hole Mac stopped (needed to hold the power button). So i decided to use Safari.

Is there a way to get this ads away? They are very annoying.

Im running the new MacBook Pro 13" with 256gb/8gb.

I hope you can help me!!!

 

I already got adblock, but it dont works I think

I try it like you said, because I downloaded my adblock version not on this way.




Grrr, english... need to write names and I with a big first letter <.<
