More details about React Developer Tools
The Components tab displays the root React components rendered on the page as well as their subcomponents.
You can edit the state and props of any component in the tree by selecting it. You can view the breadcrumbs to see the component you have selected as well as the one that created it.
You can inspect React elements on the page by switching to the React tab and then the regular Elements tab. The element will then be selected in the React tree.
You can record performance information using the Profiler tab.
This extension requires permissions in order to access the React tree of the page but it doesn't transmit any data remotely. It is completely open-source.
