Features & Capabilities

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.

User Reviews

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.

Recent reviews

I've not had any issues with this addon with the current update. I have to tweak this addon a good few times, but nothing that makes me want to give a 1 star. Anyone want to throw a site at me where they had issues?

Is Popup Blocker (strict) Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Popup Blocker (strict) requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Popup Blocker (strict) has earned a good reputation and can be trusted.
