Adblock Plus

On
http://schoener-fernsehen.com/
when i go into fullscreen, i get a black box on the right (the ad itself is blocked, but i want to remove the box).

Filter should look something like this, but i dont know how to get rid of the randomly generated part at the end.
Thanks for any help!

Is it not possible?

I tried, but anyway the black box wont be completely removed. You could try some other css addon stylish for example.

Ok, i'll look into that. Thanks alot for trying, appreciate it!
