Popupblocker can block every popup. Many websites open new windows with ads, when you try to mark text or click something. This add-on will block these and show a really small notification.

Features & Capabilities

Popupblocker is a powerful Chrome extension designed to prevent unwanted popups and new tabs that interrupt your browsing experience. It features a unique "Smart" mode that limits websites to opening only one tab at a time, reducing distractions from excessive windows. Users can customize settings with separate blacklists and whitelists, allowing control over which sites can open windows or tabs. Popupblocker operates discreetly by letting popups open briefly before blocking them, making it undetectable as a popup blocker on most websites.

Key features include blocking all new windows or tabs, configuring permissions per site, and a small notification system to inform you when popups are blocked. This add-on enhances your Chrome browsing by keeping your screen free from intrusive ads and popup clutter, giving you a cleaner and more focused web experience.

User Reviews

Popupblocker generally shines at blocking new-tab popups and is praised for its simplicity and a useful block-all-then-whitelist workflow, especially on streaming sites. However, users report inconsistent behavior across modes (blocks intended tabs or misses JS-initiated tabs), interference with legitimate actions (options, private windows, shortcuts), and occasional conflicts with other extensions or UI quirks. There’s a clear desire for easier wildcard support and override options to improve usability and reduce false positives across diverse sites.

Pros

Effectively blocks new-tab popups and unwanted windows, reducing interruptions
Simple, lightweight and easy to use
Supports a block-all-then-whitelist workflow for customization
Helpful for streaming sites to prevent repetitive ads and popups

Cons

Inconsistent behavior across modes (block all vs smart), sometimes blocking tabs you intend to open or failing to block JavaScript-initiated tabs
Can block legitimate actions (opening the add-on options, private windows) and disrupt keyboard shortcuts
Can clash with other extensions (e.g., Undo Closed Tab) and cause UI annoyances (e.g., jumping to the last tab, no page shown)
Requests for easier wildcard/domain management (e.g., wildcards for subdomains) to simplify blocklist maintenance
Some sites may still experience audio/video playback issues or other edge-case blockings

A total fail. It blocks new tabs if you intentionally try to open them (always in "block all" mode, and randomly in "smart" mode). It does not block tabs opened by JavaScript. So this add-on is doing the opposite of what it is supposed to do.

Is Popupblocker 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.

Popupblocker requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

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.

Popupblocker is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
