okay, so i'm playing a few games, right? and they have heavy mouse use in the bottom of the screen... one of those banner adds below the game is one where you scroll over it, and a huge video pops up blocking the screen! i can't plkay the game! please get rid of these adds directly below the games... they interfere
These two add-ons will solve your flash video problem. I know, those things bite, that's why I got these two things and never had that problem again.
1. With flash block: The big square in the middle of the screen is the game, so you can click on that. With the other two small squares, those are ads, right-click and select "remove this flash", and it will be gone for the remainder of that page.
have fun with it!
P.S. Staff can't remove those ads, as they bring in funds for their advertising. It's best if you just use those two add-ons for yourself, and forget about the whole incident :-)
