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)

UPD 5: Doesn't working in Google Alerts.
UP 4: Extension erased my entire list of what I've blocked over the past 2-3 years.
UPD 3: It DOESN'T WORK ANYMORE.
UPD 2: Some blocked websites still appear in search results.
UPD 1: THIS ABSOLUTELY DOES NOT WORK IN DDG. Im return to google.
does not remove from the results in the Pictures sections, etc. in the same Google & DuckDuckGo. Please fix it, i like your addon.
Thanks for SERPINFO feature, finally on other search working (uBlacklist stopped removing certain sites from the search results that I want to avoid with all my might, for example abc.site.com I write it down as *:/abc.site.com /* and *:/*.site.com/*)
Please fix it and i put 5 stars.

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.
