What are some free resources for pop-up blockers?

Some free pop-up blockers that are available from CNET include Adblock Pro, Ad Annihilator, GoGoData Toolbar and Ultra Ad Killer. CNET provides descriptions of each application along with reviews by an editor and safe links for downloading.

Pop-up blockers are applications that prevent unwanted pop-up windows from opening on a Web page. Many of these blockers also stop banner ads and protect the computer from exploits and malicious cookies during Web browsing. Pop-up blockers may run as extensions on the Web browser or as freestanding applications. They usually include an option for the user to allow pop-ups from specific sites as necessary.
