User reviews
Pros
- Effectively blocks unwanted or low-quality websites from search engine results.
- Helps improve search engine usability by filtering out spammy or irrelevant sites.
- Intuitive and easy to use interface according to some users.
- Useful for artists to block AI-generated art websites when searching for references.
Cons
- Does not consistently work across all supported search engines, especially DuckDuckGo, Bing, and Startpage.
- Sometimes fails to block already blocked sites, leading to ineffective filtering.
- Issues with UI: extension popup sometimes shows a black rectangle or unresponsive interface.
- Only hides results in search engines instead of blocking network requests, reducing effectiveness.
- The add-on occasionally works only on the initial search or tab and stops working during subsequent searches in the same tab.

Мощная штука.. я нереально удовлетворен. Остальные тупые валенки не понимают как им пользоваться поэтому пишут отзывы на 1. Но это их проблемы.
