Ads Annoying my facebook?

[Doom64]

Yesterday, I suddenly saw that my facebook was full of flash ads on the side, ads like for travian, and some scams. It was annoying so i downloaded Ad Block Plus, which took care of it ok, leaving only one thing in the place of the ad: a small blue icon with "ads by browse to save" written on the side. I thought it was taken care of

but now the ads by browse to save keeps replicating itself so that it has filled the entire side of my facebook wall. I took a screen shot :
