Popupblocker

This add-on can block every popup. Many websites open new windows with ads, when you try to mark text or click something. This add-on prevents websites from opening new windows. The "Smart" option attempts to detect and block unwanted tabs and allows no more than one new tab at a time. Most websites do not recognize Popupblocker as a popup blocker because it briefly allows popups before blocking them. Features: - Prevents websites from opening new windows - Option to prevent websites from opening new tabs - "Smart" option that prevents more than one tab from opening at a time - Is not recognized as a popup blocker by most websites
