Features & Capabilities

React Developer Tools is a powerful Chrome extension designed for developers to inspect and debug React applications efficiently. It provides an intuitive interface to explore the React component tree, view component hierarchies, and examine props and state with ease. Simply open the browser's developer tools and navigate to the "⚛️ Components" or "⚛️ Profiler" tab to get detailed insights into your React app's structure and performance.

This extension requires permission to access the page's React tree but ensures complete privacy by not transmitting any data remotely. Being fully open source, developers can review or contribute to its source code at the official GitHub repository: https://github.com/facebook/react/tree/master/packages/react-devtools-extensions. It's an essential tool for React developers aiming to enhance debugging capabilities and application optimization.

It worked well but hasn't been updated in over a year. The app breaks with the latest React/Next.js libraries due to a bug with params and searchParams in Firefox. There is last 7.1 version in Chrome that works fine. Is Firefox still supported?

Is React Developer Tools 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.

React Developer Tools requires some sensitive permissions that could impact your browser and data security. 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.

React Developer Tools has earned a fairly good reputation and likely can be trusted.
