BEST Popup Blocker for Google Crome, Mozilla Firefox and Internet Explorer

Tired of unwanted popups and popunders on sites you visit?

Pop Up Blocker blocks popups and popunders and makes you feel better.

Pop Up Blocker automatically blocks spyware and adware pop-up and pop-under ads. It also helps you choose which windows to close with the block list feature. This means the more you use Pop Up Blocker, the fewer pop-up ads you see. Pop Up Blocker blocks advertisement in the forms of inline videos, background sounds, JAVA applets, animated GIF files, Macromedia Flash movies, and video and flashing banner ads (ICQ, AOL Instant Messenger service, MSN Messenger), and all major video formats.

Pop Up Blocker also protects your home page setting from being forcibly hijacked by malicious Web sites and spyware, which modifies your default start page.
