But it even does it when I shut off Adblock plus.

Also got a new problem. Windows Live wont work anymore. It's stuck at https://dub131.mail.live.com/default.aspx
It then just shows a white page.

Adblock plus. Got it working now with Stylish for Opera and then using the lines of code from the other thread.

I saw that but I still don't know what to do. I have tried to put those 2 lines of code in a .css file but it doesn't work.

I've read the thread you suggested but I still don't know what to do. This thread seems to be about removing the youtube topbar and not about removing big open spaces on sites.

Is there a way I can get rid of the big white open spaces that are left by the ads that get removed by ad-blockers. I used to have this but I just reinstalled my PC and forgot to backup these files. I think it had something to do with CSS or JavaScript.
