## Description

Popup Blocker (strict) is a lightweight and effective Chrome extension designed to prevent websites from opening unwanted popups. It strictly blocks all popup requests by default, notifying users each time a popup attempt is made. Users have the flexibility to accept or deny popup requests, open them in background tabs, or redirect the current page to the popup URL.

This extension consolidates multiple popup requests for the same URL into a single notification with a count badge for clarity. It supports blocking via multiple methods including window.open, target _blank links, and iframe submits. Popup Blocker (strict) enhances browsing safety and user control by pausing all window opening attempts until user action is taken, ensuring no disruptive popups appear without explicit permission.

## Review summary

Users praise strong, aggressive popup blocking and granular controls, plus helpful indicators, but warn it can break sites, cause 404s when permitting popups, and be hard to configure and resource-intensive. Compatibility variability across sites and browsers is also noted, making it powerful yet finicky in practice.

### Pros

- Aggressive popup blocking that reduces nuisance on most sites.
- Fine-grained control with trust/whitelist options to allow certain links permanently or temporarily.
- Blocks redirects and popup-triggering elements, minimizing ads and intrusive content.
- Helpful UI cues like the number of popup requests and a preview window to gauge activity.
- Can reduce the need for a separate ad-block extension thanks to its blocking capabilities.

### Cons

- Can break websites and make pages unusable.
- Not always reliable: can produce 404s when trying to allow a popup and show inconsistent blocking on some sites.
- Difficult to configure or overly complex for a typical user.
- Consumes noticeable RAM and drains power.
- Site-specific compatibility issues (some sites demand accepting/trusting actions or aren’t fully blocked) across different sites/browsers.
