1Blocker vs AdNauseam

1Blocker is an ad and content blocker for Apple devices, with Safari filtering, custom rules and options for tracker and cookie-popup blocking. Its Safari content blocker filters ads, cookie banners, annoyances and trackers; the separate 1Blocker Scripts extension targets harder-to-block ads and annoyances, including YouTube video ads. On iOS, an in-app tracking filter uses a local VPN profile to block invisible trackers across apps. 1Blocker says filtering happens locally and that the app does not collect personal information or track visited sites. Listed platforms are iOS, macOS and browser extension, with visionOS also supported. Requirements are iOS 16.0 or later and macOS 13.0 Ventura or later. Free mode permits one blocking filter at a time and custom rules. A 14-day trial is listed. Paid options are $2.99 a month, $14.99 a year and a lifetime plan listed at $39.99 a month, described as a one-time payment. Premium includes multiple categories, filter updates and in-app tracker protection.

AdNauseam is a free browser extension intended for people who want to resist advertising surveillance and tracking. Built on uBlock Origin, it blocks ads and quietly simulates clicks on blocked ads to add noise to advertising networks’ user profiles. Its interactive AdVault lets users inspect and explore captured advertisements. The FAQ says simulated clicks run as background requests, with responses discarded rather than executed in the browser.

AdNauseam supports major browsers, including Chromium-based browsers and Firefox derivatives, and is available on desktop and mobile. The Firefox add-on page lists availability for Firefox on Android. Google Chrome requires workarounds because the extension was disallowed there; the installation instructions describe those workarounds as temporary. The extension does not collect or click ads in private or incognito windows unless enabled manually. Its developer reports that it does not require data collection, while its Firefox add-on permissions include access to privacy settings, tabs, navigation activity, and data for all websites. It is licensed under GNU General Public License v3.0 only and is offered at free.
