Pop-up Blocking

Pop-up Blocker: Stop Pop-ups and Redirect Ads

ProBlocker blocks pop-up windows, overlay interstitials, and redirect scripts that open new tabs without your input. It works at the network level — pop-up scripts never execute.

What Pop-ups Does ProBlocker Block?

  • Pop-up windows — new browser windows opened by ad scripts
  • New-tab redirects — scripts that silently open a new tab to an ad
  • Overlay interstitials — full-page overlays that cover content and require dismissal
  • Exit-intent pop-ups — pop-ups triggered when moving the cursor toward the browser chrome
  • Newsletter capture overlays that use known pop-up ad networks

How Pop-up Blocking Works

Pop-ups are usually triggered by JavaScript loaded from third-party ad networks. ProBlocker cancels the network request to the pop-up script before it loads — so the script never executes and the pop-up never appears. This is more reliable than browser pop-up blocking, which only stops the window after the script has already run.

Does Chrome Already Block Pop-ups?

Chrome has a built-in pop-up blocker that prevents new windows from opening when you haven't clicked a link. However, it does not block overlay ads, exit-intent pop-ups, or scripts that use window.open() with user-interaction workarounds. ProBlocker blocks the underlying ad network scripts that power these, regardless of how they trigger.
