Microsoft Edge extension API roadmap
Note
This documentation is for extensions for the legacy version of Microsoft Edge. For information on the new Microsoft Edge, see Microsoft Edge (Chromium) Extensions.
Important
The new Microsoft Edge program is now open to accept chromium-based extensions for the new Microsoft Edge (v77 or later). If you want to submit a new extension, visit Publish to Microsoft Edge (Chromium) Add-ons Store to learn about the submission process.
With this announcement, Microsoft is no longer accepting new extensions for the legacy version of Microsoft Edge. If you own an Extension for the legacy version, you should begin the process of porting your Extension to the new Microsoft Edge. The new Microsoft Edge is based on Chromium, so Extensions designed for the legacy version of Microsoft Edge do not work with the new version.
In addition to web APIs, the extension API allows extensions to achieve deeper integration with the browser host. This API gives developers access to Microsoft Edge’s browser features such as tab and window manipulation. The following table details what APIs are supported/in development for Windows 10 publicly released builds of Microsoft Edge.
