> A curated list of awesome resources for WebExtensions development.



WebExtensions are a cross-browser system for developing browser add-ons. To a large extent the system is compatible with the extension API supported by Google Chrome. Extensions written for this browser will in most cases run in Firefox with just [a few changes](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Porting_a_Google_Chrome_extension).
