Features & Capabilities

The Google Analytics Opt-out Chrome extension empowers users to protect their privacy by preventing Google Analytics and Tag Manager JavaScript APIs from collecting data. Unlike traditional ad blockers, this extension does not block web requests; instead, it adds an object to every webpage requesting the analytics APIs not to track the user.

Supporting popular analytic scripts like ga.js, analytics.js, and dc.js, the extension ensures that both Google Analytics and Tag Manager scripts respect your privacy. When tracking requests are rejected, the extension's page action button becomes colorful and displays the count of rejected requests on hover, providing transparency and control for users.

Additionally, the extension supports Adobe Analytics, making it a versatile tool for users aiming to reduce data collection by major analytics services. Simple to use and respectful of browsing experience, it is an essential add-on for privacy-conscious users.

This extension is simple but effective for anyone who wants to stop Google Analytics from tracking their activity. It blocks the analytics and Tag Manager scripts from collecting data, helping protect your privacy while browsing. It works quietly in the background without affecting how websites function. Great for users who want more control over their data and online footprint.

Is Google Analytics Opt-out Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Google Analytics Opt-out requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Google Analytics Opt-out has earned a fairly good reputation and likely can be trusted.
