User reviews

Users appreciate uBlacklist for effectively blocking unwanted sites across multiple search engines and improving search experience. However, many report frequent malfunctions, including the extension failing to work consistently, intrusive update-induced dialogs, and feature changes without consultation. Issues with inconsistent blocking behavior across search engines and tabs persist. Despite these drawbacks, the add-on remains a valued tool for making search results cleaner and more manageable.

Provides a helpful feature to block entire sites or specific pages, useful especially for blocking AI art websites.

Highly valued by users for reducing noise in search results and improving browsing experience.

Cons

Frequent instability and flakiness; the add-on often stops working and requires restarting the browser or reinstalling.
Recent updates have introduced intrusive dialogs on every visited site, disrupting user experience.
Features that previously existed were removed or changed without user consultation, causing dissatisfaction.
Blocking functionality inconsistently works across different tabs and search engines, especially with StartPage and DuckDuckGo.

Extension safety

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 Browser Add-ons, 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.
