I use Mozilla-Firefox too and I have the banners set here to view because I get to see new products that way. I don't bother checking the new releases because I keep forgetting too. 

However, if I'm going to keep seeing banners unrelated to this site, I will block them.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
