Privacy Possum is a powerful Chrome extension designed to protect your online privacy by interfering with common commercial tracking methods. Unlike traditional blockers that simply block trackers, Privacy Possum reduces and falsifies the data collected by tracking companies, making it harder for them to build accurate profiles about your browsing habits. This approach effectively 'monkey wrenches' tracking techniques without breaking website functionality. Easy to install and use, Privacy Possum enhances your web experience by minimizing your digital footprint and keeping your personal information private.

User reviews

Privacy Possum is praised for effectively blocking trackers and being simple, reliable, and open-source. However, it has not been updated since 2019 and causes breakages on some sites like Google Maps and video players. Users find it useful but wish for updates and better control over its settings.

Pros

Effectively blocks various tracking methods including tracking headers and third-party cookies.
Simple and easy to use with minimal user intervention required.
Runs quietly in the background without crashing the browser.
Open-source, providing transparency and security assurance.
Still functions well despite lack of updates.

Cons

No updates since July 2019, making it feel abandoned.
Breaks certain website functionalities like Google Maps panning and embedded videos on YouTube.
Occasionally causes issues such as empty pages on some sites (e.g., wishlist on iHerb) and blocks video streams on some players.
Lacks a user-friendly interface to toggle global settings on or off.
