Compatibility/Mobile

Mobile Web Compatibility

With Mozilla's mobile offerings (Firefox for Android and Firefox OS), Mozilla controls only part of the user experience – delivering the products. The other part of the user experience is controlled by the mobile Web content that is available. The current state of the mobile Web is not one of standards compliance but one of user agent (UA) sniffing and Webkit specific functionality. We need to open up the mobile Web to other rendering engines like Gecko, Presto, and Trident.

There are 4 key problem areas that must be addressed:

1. user agent (UA) detection
2. Webkit prefixed CSS
3. Webkit specific DOM/JS/content
4. Gecko limitations

Goal

The vague goal for this project is to open up the mobile Web to non Webkit based browsers.

A specific project goal is being defined by the market insights, product, and project management teams.

Scope

In scope

• Any site with a mobile version
• Any locale

Out of scope

• Site enhancements
• Trivial site layout or functional bugs
