Reduce Firefox startup time on ARM

Registered by Emmet Hikory on 2011-04-21

Investigate why firefox takes a long time to start up on ARM devices. This is almost certainly due to lots of IO. Upstream is aware this is an area of FF that needs attention and they are working on it (targetting desktop Win/Lin). Firefox 6 or Firefox 7 is planned to be part of Ubuntu 11.10. Both of these releases have startup time improvements on their upstream roadmap.
The use of slow SD in our case just makes the issue more visible.
