Mozilla documentation on WebExtensions.
Here’s a centralized repository of the migration status for various high impact AMO content based on popularity, unique functionality, or otherwise. Please note if an extension is labeled “WebExtension or Beta on AMO” in the right-most “WebExtension” column, that means it has either already migrated, or is in beta form (to find a beta version, scroll to the bottom of the extension’s listing page on AMO and click “Development Channel”); if an extension has no label under the WebExtension column, there may be a tracker that leads to more info.
If there’s an extension you’re interested in that you don’t see on this page, there is a replacement finder tool. There’s also a Discourse discussion about potential alternative replacements for various legacy content as well as a Frequently Asked Questions guide.
