Firefox/Projects/Rebuild Software Update without browser element

Overview

Sprint lead: rs
Sprinters: rs, beltzner

Description

Instead of a page that has a browser element, change the update snippet format to include references to resources (images, text) which will be assembled in a XUL dialog on the client side.

Goals / Use Cases

• Removing the browser element will remove the requirement to verify the size of the billboard content per locale.
• Make the ui look more like it is part of the application.

Non Goals

Design

The updater window should look like this-ish:

with:

• a background image (stored as a data URI in the update snippet)
• a logo image (stored as a data URI in the update snippet)
• large header text (stored as text data in the update snippet)
• bold subheader text (stored as text data in the update snippet)
• description text (stored as text data in the update snippet)
