Support for transitioning and porting to WebExtensions

Office hours schedule

WebExtensions are the new standard for add-on development in Firefox that is cross-browser compatible, allowing you to maintain one codebase for extensions that work in multiple browsers. With the release of Firefox 57 in November 2017, legacy add-ons will no longer be supported.

If you want to transition your Firefox legacy add-on or port a Chrome extension, we're here to help!

Below is a schedule of when help is available in the #webextensions channel at and in the add-on development forum. Names are listed as IRC nicknames so you can reach those people directly. We also encourage you to join the webextensions-support [at] mozilla [dot] org mailing list to ask questions and support other developers. Times will automatically display in the time zone of your device.
