Nice addon. Helps me avoiding some crappy site that "offer" me to download software I can get directly from develper's home page.

Unfortunately, it has recently gone freemium, and the free version now allows only 6 entries in the block list.
Not a big problem for me, since I'm currently blocking only 2-3 domains: however, if my needs will change, I think I'll consider anothe option,after all there's plenty of alternatives around.
