AdNauseam vs Ghostery

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.

Ghostery is a free, open-source browser extension combining ad blocking, tracker protection, cookie-consent handling, and tracker information tools. It blocks banners, video ads, pop-ups, and sponsored content. The Tracker Panel displays trackers it identifies and neutralizes, while WhoTracks.Me provides information about tracking activity and companies. Ghostery says its protection replaces personal identifiers with random values. Never-Consent rejects tracking cookies and sends opt-out signals on supported sites. Supported browsers include Chrome, Firefox, Edge, Opera, Safari, and Brave, and users can install the extension on as many devices as they like. On iOS and iPadOS, it offers Safari protection; on Android, it supports Edge and Firefox. Chrome on Android is unavailable because Chrome does not allow extensions there. Ghostery says extension telemetry is non-personal, with additional telemetry sent if users opt in. For phishing and malware protection, it says it sends a partial URL checksum to its backend rather than the full URL. Private Search is in closed beta.
