AdBlock vs uBlock Origin

AdBlock blocks ads across desktop and mobile devices, with support for Windows, macOS, iOS, and Android. It works with major browsers and includes custom filter lists, an element picker, and cookie popup blocking. A free plan is available, alongside Premium at $4 a month. Premium includes a 7-day free trial; the subscription starts on day 8 unless cancelled. Listed Premium features are AdBlock VPN, enhanced YouTube blocking, cookie-consent blocking, and distraction controls. Pricing is also described as paid from $40/yr. The maker, AdBlock, was founded in 2009 and is headquartered in Houston, Texas, United States. Device coverage is listed as desktop and mobile. The platform list names four operating systems, while browser support is described as covering major browsers.

uBlock Origin is a free, open-source content blocker for desktop and Android versions of Firefox, as well as Chromium and Thunderbird versions. It blocks ads, trackers, coin miners, popups, anti-blockers, and malware sites by default. Several filter lists are built in, and users can add lists and hosts files or create custom rules using EasyList syntax with uBlock Origin extensions. If blocking is too broad, users can disable preselected lists. The basic and advanced popup interfaces include a per-site point-and-click firewall. The project’s stated purpose is to help users neutralize privacy-invading methods in the browser, and it is described as CPU- and memory-efficient, fast, and lean. It works best on Firefox and also supports Chromium-based browsers, including Edge and Opera. In Thunderbird, it affects feeds but not email. The project advises against running it alongside another content blocker. It is licensed under GPL-3.0/GPLv3, and enterprise deployment documentation is available.
