Moderate review signal

Listing & review signals
Observed signals from store listing text and review samples.

Listing positioning

Positions itself as a strict, single-purpose tool designed to block pop-ups and pop-unders before they are issued. It explicitly positions itself as a complementary tool to be used alongside ad blockers like uBlock Origin rather than a replacement.

Inferred product pattern

A single-purpose utility focusing on browser event interception to complement general-purpose ad-blocking software.

Review-backed pain points

Users report that the extension occasionally stops working entirely after updates. Some find the notifications used to signal a blocked popup to be just as disruptive as the pop-ups themselves.

Observed feature gaps

Lack of a manual 'hard block' list to silence notifications for specific annoying sites; cannot block overlay/cookie banners (as stated in listing).

Store description excerpt
Short excerpt from the public Chrome Web Store listing; full copy is available on the official store page.
It is common for streaming, shopping, and WordPress sites to open unwanted pop-ups or redirect users to ad pages. This free, open-source Chrome extension blocks all types of popups and popunders before they are issued. It pauses window opening requests for user attention. Unlike other popup and ad blocker extensions, this one blocks requests on the original page rather than closing the target pages. You will get badge count and optional page notification when a popup is blocked. A badge counter over the notification increments if more than one identical request is issued. For previously visited sites, the extension automatically allows or denies requests. It identifies the action based on your previous decision.
