view story

http://ubuntuforums.org – Hi, I am using Chrome on ubuntu 10.10. When I open a particular website(torrent) it is automatically one webpage which i don't want. I have blocked the pop-ups and even put an entry in /etc/hosts (as unwanted websites), but it is still pop-ups. Can anybody help me? Thank you in advance. (Hardware)
