User reviews

Users appreciate uBlacklist for improving search engine experiences by blocking unwanted or low-quality sites and find it especially helpful for filtering AI art sites. However, many encounter issues with inconsistent functionality across different search engines like DuckDuckGo, Bing, and Startpage, where blocking does not always work or sites reappear. The extension's UI sometimes malfunctions, and it only hides search results rather than blocking network requests, limiting effectiveness. Overall, while powerful and useful, uBlacklist has reliability and usability challenges reported by multiple users.

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. Это просто бомба приложение! Не без недочетов, но все-же
