User Reviews

Users praise uBlacklist for cleaning up search results by blocking unwanted sites across engines and managing blocks via lists. It performs well on desktop with features like inline blocking, blocked-results toggle, and import/subscription lists, and can remove noisy domains from image search. However, mobile reliability is repeatedly cited as a issue, UI controls can vanish or change, and privacy prompts or persistent notifications raise concerns. Engine-specific quirks (DuckDuckGo, Qwant) and update-related breakage are also noted. Overall, strong with caveats for mobile use and maintenance.

Pros

Reduces junk and noisy results, keeping search results clean
Works across multiple search engines (Google, DuckDuckGo, Bing) and platforms
Allows viewing blocked results via a toggle or inline option
Supports blocking lists and subscription lists for easy site-wide blocking
Effective at blocking unwanted domains in image search and shopping results

Cons

Unreliable on mobile (Google searches and Android) or may stop working on mobile
Blocking controls can be hidden or change with updates (buttons disappear, top-of-page toggle may be confusing)
Privacy/permission concerns (broad data-access prompts and persistent notification icon on many sites)
Some engines lack full support or breakage occurs (e.g., DuckDuckGo issues; Qwant support not available)

Weird. For some reason, it is not working on Ecosia.

Used to work on google and DDG (though not in mobile browser for DDG). Now it updated and both "block this site" and "show blocked results" are gone. Edit: apparently the last good version is 8.12.0. Everything after that is broken.

Is uBlacklist 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.

uBlacklist requires a lot of sensitive permissions. Exercise caution before installing.

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.

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