Does Firefox have a add-on which can block this stickr pop-up ?

I think we'd all like that.

The NoWires plugin is average. It's worth more like 5 to 10 dollars. Photoshop tools work much better for complicated messes of lines.

Congratulations and a really nice idea this STICKR.I like it. Only one thing I do not understand why you did it only in English ad Russian?

I like this great group.Their songs so much emotion.Addicted,I Can Wait Forever,Me Against the World,My Alien,Untitled...Sooo cool :)
