Without a doubt an essential must-have addon for anyone browsing the web.

Best ad blocker ever, once you configure it properly with extra filter lists its even better.

Not sure if the extension is causing the problem but on youtube it constantly reloads the page if i do anything like click fullscreen.

TOP extension 💯🔥

On May 4, 2025, Raymond Hill, the lead developer of uBlock Origin, removed Ukrainian filters from the regional section without any explanation. These filters were created by Ukrainians for Ukrainians, and were developed and optimized with attention to each individual website in the Ukrainian segment of the internet. They were highly effective in blocking ads, phishing, and other unwanted content on Ukrainian sites.

Instead, they were replaced by Russian filters (RU AdList and the so-called "Ukrainian" filters from the Russian company AdGuard). These are overloaded with blocking rules tailored for the Russian web (Runet) rather than the Ukrainian segment. I don't even understand why AdGuard labels them as "Ukrainian regional" when the only thing Ukrainian about them is the name, while the filters themselves are clearly made for the Russian region.

Moreover, these Russian filters are of very poor quality and ineffective at blocking ads, phishing, and other threats on Ukrainian websites. Literally, after the first attempt to use these filters, I started seeing ads for online casinos and other garbage right away.

To make things worse, these Russian filters contain politically motivated blocklists — they block absolutely all Ukrainian charity foundations individually.

As a Ukrainian user, I am outraged by the developer’s position.
