Hi, I am working on porting over a Chrome extension to Firefox. However with the temporary add on installed in Firefox, I keep getting “ReferenceError: chrome is not defined”. I am trying to send a message from my content script to my background.js file in the extension. Everything works perfectly …

Chrome is not defined

There is a difference. chrome returns a callback function and browser returns a promise.
