by Firefox user 13589459, 7 years agoExtension is awesome. Mozilla Foundation, on the other hand...Guys, we get that you want to promote Firefox {version}, but for the love of Bob, quit screwing with the links! I'm trying to install uBlock Origin inside Thunderbird, which used to work just fine...now all I get are "Only on Firefox - Get Firefox Now!" links which, do not, allow such an installation. And yes, I can download an older version of uBlock Origin through some trickery (and prayer), but the fact remains: you're causing trouble for the Thunderbird people! Stop it!

- Rated 1 out of 5by Firefox user 14655365, a day agoOn 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. - Rated 5 out of 5by Firefox user 18967671, a day ago

- Rated 5 out of 5by Nauta Caeli, 2 days agoExceptionally effective and lightweight. Blocks ads and trackers without slowing things down. A must-have for clean, fast browsing.
