FF3.6 and xulrunner 1.9.2 are based on the same code base
FF4 and xulrunner 2.0 are based on the same code base

When you install FF4 on Fedora14 there will be two versions of xulrunner

The issues becomes one of cost benefit. What is the cost of OLPC, AC, or
individual deployments supporting a version of xulrunner which is not supported
or QAed by fedora vs. the benefit of having ff4 in the os.

My guess is that the cost will exceed the benefit.  So AC will not back port,
QA, or support ff4 on DX12 unless someone else takes the lead. But the beauty of
a community project is that if anyone else thinks that benefit is greater than
the cost they are welcome and encouraged to 'make it happen.'

over features and performance.
