- @newbieeeeeeee: there isn't a way to use it in plain JS; write your own hammer-based event launcher. – dandavis Commented Sep 22, 2017 at 9:13

Reset to default 12Right now, there is no API for watching the cookies.
This browser.cookies.onChanged that you refer to is only for browser extension https://developer.mozilla/en-US/docs/Mozilla/Add-ons/WebExtensions/API/cookies/onChanged.
You can use the following npm package https://www.npmjs./package/@fcannizzaro/react-use-cookie-watcher.
If you check the implementation, it just adds a setInterval which reads cookies and waits for changes https://github./fcannizzaro/react-use-cookie-watcher/blob/9281ec0a5b6fbcbafd4589f0ea32d2b59bec32b3/src/index.tsx#L31.
So you can do it on your own if you want
