## Review summary

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)
