Firefox keeps crashing

Can someone please help me with Firefox. It is installed through NitoTV and I can go into it through NIto and I am running mobile airmouse on my iphone to operate, however Firefox comes up and loads the internet as normal, but about a minute later the screen just goes black with a tiny strip of white along the top of the screen. When I press the menu button on the apple remote, it goes back to the apple tv menu.

Any suggestions???

Were you ever prompted to updated Firefox? If so, did you install the update? The 2.x version of Firefox is the best version for running on the AppleTV.
