Questions tagged [firefox-addon-sdk]

The Add-on SDK is a set of tools and APIs that allow you to create Firefox add-ons using standard web technologies (HTML, CSS, and JavaScript). The SDK includes APIs, a test framework and documentation as well as a command-line tool for creating, running and testing extensions.

The Add-on SDK was an API for creating simple Firefox extensions using standard web technologies (HTML, CSS, and JavaScript). The SDK included APIs, a test framework and documentation as well as a command-line tool for creating, running and testing extensions. Earlier versions of the Add-on SDK were released under the name Jetpack.

The Add-on SDK was deprecated in Firefox 53 and EOL'd in Firefox 57 in favor of WebExtensions. The Add-on SDK is now considered to be a legacy technology, as extensions built with it will not work after Firefox 57.

For general information about Firefox add-ons incl. SDK add-ons, see the tag.
