AdBlocker Ultimate vs uBlock Origin Lite

AdBlocker Ultimate blocks ads and trackers in browsers, apps and across devices, with products for Windows, Android and iOS as well as browser extensions. Its Windows app adds system-level ad and tracker blocking, phishing protection and customizable exceptions. Android offers system-wide filtering, per-app controls, malware and phishing protection, custom filter rules and encrypted DNS, including DNS-over-HTTPS, DNS-over-TLS and DNSCrypt. The iOS product blocks ads, malicious domains and trackers in Safari and supports custom filters and a whitelist. Browser extensions are listed for Chrome, Firefox, Opera, Yandex and Edge; they do not use a predefined acceptable-ads list. The maker says filtering is processed locally and browsing history is not tracked. A free plan and 14-day trial are available. Listed yearly plans cost $39.99 a year for either 3 or 10 devices; lifetime licenses cost $99.99 as a one-time purchase for either device count.

uBlock Origin Lite is a free, open-source content-blocking extension built on the Manifest V3 API. It blocks ads, trackers, miners, and other content after installation. Its default rules include uBlock Origin lists, EasyList, EasyPrivacy, and Peter Lowe’s ad and tracking server list. Users can add rulesets, custom filters, and filter lists, and use an element picker and cookie-popup blocking. Filtering is declarative, so no permanent process is required; the project says the browser performs CSS and JavaScript injection and the extension itself uses no CPU or memory while blocking. The project says it collects no data, has no analytics or telemetry hooks, and makes no remote requests except for filter lists users explicitly subscribe to. Users can allow all-site filtering or reduce host permissions. It warns Lite is not an automatic uBlock Origin replacement and may be less effective against anti-blocker sites or breakage.
