Adblock Plus vs AdBlocker Ultimate

Adblock Plus is a browser extension and mobile ad-blocking product that filters ads, third-party tracking requests and malicious domains using lists such as EasyList and EasyPrivacy. It blocks formats including video ads, banners, pop-ups and pop-unders, and can disable social buttons. Acceptable Ads are enabled by default, but users can turn that feature off. Users can also remove default filter lists, add other lists or create their own. EasyPrivacy targets tracking domains, fingerprinting scripts, analytics requests and data-collection domains. The desktop add-on supports Chrome, Firefox, Safari, Microsoft Edge, Opera and Yandex Browser. Mobile options include a Safari app for iOS, a product for Samsung Internet on Android and the separate Adblock Browser. The extension can access page URLs and content to block or hide ads; it does not track browsing history, record form typing or alter submitted data. Free ad blocking is available. Premium is listed at $4 a month or $40 a year.

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.
