Marketplace/Add-ons/Validation

The Marketplace has been placed into maintenance mode. It is no longer under active development. You can read complete details here.

Current stated support of chrome extension manifest spec can be found on https://wiki.mozilla.org/WebExtensions#Packaging_2.

However, the stated spec is not in sync with FxOS.

Manifest fields intersection

• Required: name, version
• Recommended: default_locale, description
• Single optional: browser_action
• Optional: background, content_scripts, permissions, web_accessible_resources

Also supported in Firefox OS 2.5

These fields are supported in Firefox OS 2.5, though not stated as supported by the WebExtensions wiki page:

• Recommended: icons
• Optional: author (mapped to developer.name)

Outstanding questions

• browser_action does this imply support for chrome.browserAction.*?
• background this feels like it's being replaced by event pages, even by Google.
• permissions are the permissions supported the same as the list for Chrome?

Marketplace validation of manifest directives

Bolded items mark more specificity than stated by Mozilla or Google (as of version 2). All validation as of launch can be found here.
