JavaScript Popup Blocker

JavaScript Popup Blocker is a simple yet powerful popup blocker for JavaScript created popups and pop-unders.

It blocks popups that Chrome's popup blocker doesn't, like the ones that appear when you click anywhere on a page for example. You can use JavaScript Popup Blocker in 2 modes: Whitelist mode: Blocks all popups except ones of whitelisted pages, or Blacklist mode: Only blocks popups of blacklisted pages.
