Features & Capabilities

The WebAPI Manager Chrome extension empowers users to improve their browser security and privacy by selectively controlling web pages' access to different browser Web APIs. Users can create custom rule sets for specific domains, limiting websites to only the functionality they require, reducing exposure to seldom-used or privacy-compromising features like Web Audio API, WebGL, or the Ambient Light Sensor API. This granular control helps minimize attack surfaces and tracking vectors such as fingerprinting.

With over 1,400 JavaScript methods categorized into 74 Web API standards, the extension offers domain-specific functionality blocking through regex matching, default fallback rules, and a smart blocking method that minimizes disruption to existing web page code. While currently unmaintained, WebAPI Manager is based on academic research from the University of Illinois at Chicago’s BITSLab and continues to be a valuable tool for privacy-conscious users aiming to secure their browsing experience.

Is WebAPI Manager 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.

WebAPI Manager requires a lot of sensitive permissions. Exercise caution before installing.

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.

WebAPI Manager has earned a fairly good reputation and likely can be trusted.
