Is React Developer Tools safe?
React Developer Tools posts its stored DevTools settings into every page where its hook runs.
React Developer Tools registers scripts on all URLs and uses a page message handshake when installing its React hook. During that handshake, it reads all local DevTools settings from browser storage and posts them back through window.postMessage, where scripts on the page can observe the settings values.
