Sites with too much ad's ?

Ever get cut off with going to a site and getting constant popups or annoying ad's ?
now thats something we all hate, like the Google ad's on the YouTube videos.
How much do you hate it ?
Do you use extensions like ad blocker ?

Now add blocker is the nice's extension/add-on I have used. It blocks ad's before it download, so you stay ad free. It also work's on YouTube
try it now for Chrome or Firefox

really one or two or even three ad's is enough for me but popups and a thousandths of ad's is annoying!
Some anti viruses come with an add banner remover.....

Do you hate ad's ?
