Browser Extension Helpers

Promisified, cross-browser wrappers and helpers for extension APIs.

• Normalized & Promisified: no more fussing with Chrome's irregular callbacks, all functions returns a promise
• Simple: hide the browser.api.action boilerplate behind function calls
• Cross-Browser: use the same functions on Chrome, Firefox, or Edge

Note: Many APIs are not supported in Edge. Check their documentation.
