The Firefox version of uBlock Origin is considered the version that offers the best protection, as it supports protection against CNAME tracking, which the Chrome versions do not offer.
Hill calls uBlock Origin a "wide-spectrum content blocker" instead of an ad blocker. The extension blocks more advertisement but also trackers, miners, popups, malicious URLs and more by default. Users may add more lists, for instance to deal with annoyances on the Internet.
Many users hold uBlock Origin in high regard because of its memory and CPU effectiveness. Hill, who never accepted donations or compensation for his development work, is another core reason why the extension is as popular as it is right now.
