So in my opinion it doesn't make a big difference if you install Firefox or XULRunner.
I presume those mobile devices lack the processing power and ram space to run a fullscale Firefox, so I think a lightweight and standalone epub reader will be usefule for those devices.
Since XULRunner is 90% Firefox as your described, I guess it's not a good choice.
Anyway, thanx for your reply.
