LocatorJS Firefox

LocatorJS

A Firefox extension that allows you to click through from your React app to its code.

Features & Capabilities

LocatorJS is a Firefox extension designed specifically for ReactJS developers, allowing you to option-click (or alt-click) on any React app running in development mode to instantly jump to its underlying source code. This tool is especially useful during local development where React apps are commonly run in localhost environments.

Built upon the open-source LocatorJS dev-stack plugin, this extension enhances productivity by seamlessly connecting what you see in the browser with the corresponding code, drastically simplifying debugging and code exploration workflows.

Is LocatorJS 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.

LocatorJS requires a few 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.

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