hello dsgd47, unfortunately the artificial limitations microsoft has built-in into its operating system make it impossible for third-party browser vendors like mozilla to offer their product for the windows rt platform.
Actually, those are articles are from 5 months ago and they are no longer correct (if they ever were). Having worked on several apps myself for the RT, I have not seen anything that would cause such problems. (The programs used telnet, http, and DataGramSockets to talk over the net.) If this was REALLY a problem, I expect that the European Union and the Feds would have already come knocking at the door, given the anti-trust issues that MS had regarding IE over the past 20+ years.
I was hoping that we had gotten past the knee-jerk responses and had someone really look at the situation.
microsoft's standpoint might be that on ARM they're competing with ios and android and are far from any market share that comes close to a monopoly or a dominant position which would warrant for anti-trust action.
