Not too long ago we kicked off an analysis to answer the question,
Does aliasing a subset of Webkit CSS properties in Gecko improve mobile Web compatibility?
The preliminary results of our small study showed little improvement. The next step in this analysis is to understand why the sites that were tested are broken even when aliasing Webkit prefixes in Firefox.
Results can be reported by filing bugs against the Tech Evangelism: Mobile component or by sending them to the compatibility mailing list.
