В последнее время не блокирует рекламу в сервисах яндекса.

The first extension that I've download in Firefox, it's lightweight, it's good block ads and tracker I guess that more than enough there literally nothing to complain,this extension can be consider perfect.

This extension is one of the rare best things i use for privacy on internet.

Very good. Blocks ads very well.

uBlock has been one of the best additions to Firefox since, maybe, NoScript. It's capabilities and features should be built-in and standard. The web is a troubled place with ads, tracking, and malicious connections in nearly every request.
