I am unable to launch Firefox mobile for my phone. It opens a black window, then closes out.

I haven't not been able to get Firefox to work on my phone yet. I tried both the ARMv7 version then the ARMv6 version.

I have a T-Mobile myTouch 3G, with the latest Android 2.2 Froyo update from T-Mobile.

I recently restored my device to factory settings. It will still refuse to launch.
