Question for converting Firefox addon to Chomium extension

[mikhoul]

I'm migrating to Chromium from Firefox but I have some addons that use promise that I'd like to convert.

Those addons like this one use promise and so they return errors like this: https://i.imgur.com/H8UYYFY.png

What would be the most easy way (since I'm not really fluent with JS) to convert them, would it be by loading the polyfill.js script from the manifest.json and adding something like that in the beginning of the .js files of the addon ??

var browser = new polyfill();

Regards

Unfortunately browser is not a Promise javascript object. It is a Javascript object specific to Firefox, so this library can't be of any help.

Here are the docs on the firefox version
https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/storage
and for Chrome
https://developer.chrome.com/apps/storage

You need to translate to the Chrome version.
