Compatibility/Mobile
Mobile Web Compatibility
What Are Web Compatibility Issues?
A person should be able to use the Web with whichever device and browser they are using.
Unfortunately, some developers by choice or negligence will make their Web sites unusable by specific devices or browsers. We need to open up the Web to any rendering engines (Blink, Gecko, Trident, etc.) and/or browsers, when used on mobile devices.
There are 4 key problem areas that must be addressed:
- user agent (UA) detection
- specific CSS prefixes (such as WebKit)
- specific DOM/JS/content (such as WebKit)
- Gecko limitations (for Mozilla)
Goal
The vague goal for this project is to open up the mobile Web to all 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
- Firefox Marketplace app testing
Get Involved
Fixing the Web will only be successful with the efforts of everyone (Web site developers, Volunteers, Partners, and Mozilla employees). Mozilla can't do it alone.

Projects
Web Compatibility is wide. There are many possible projects around this topics. Some are currently active, some are either would be good to do or have been actually done.
User Agent (UA) Overrides - In progress
owner: kdubost
The UA override mechanism allows B2G and Firefox Android to force mobile content by sending a custom UA to a specified domain.
Fixing UA detection libraries - In progress
owner: miketaylr
User Agent detection libraries sometimes do not take into account Firefox OS and/or Firefox for Android. We (Mozilla and the community) try to contact them to fix the libraries.
Evangelism - In progress
Part of the Evangelism effort, the Web Compatibility Guide helps individuals to report, analyze and contact Web sites for issues with Web Compatibility. (work in progress)
(Mobile) Library and Framework Investigation - In progress
The ongoing goal of this project is to "audit" source code and issues/bug trackers of popular mobile frameworks to identify bugs, workarounds, or performance issues that need increased attention from Mozilla.
Video project - In progress
owner: hallvors
The Video project aims to get an overview of and improve the compatibility state of video watching sites.
90% Mobile Compatibility for the Alexa Top 1000 Sites - Backlog
90% Mobile Compatibility for the Alexa Top 1000 Sites to achieve 90% compatibility in terms of mobile content sent to Firefox for Android and Firefox OS by the Alexa top 1000 global sites.
