I have been unable to use the app Firefox for Android on my Nook HD recently, although I have been able to in the past. This problem has persisted for at least the past week. Whenever I click on the app's icon, it tries to open the Nook shop, and then says that the Nook shop has stopped responding. When I open up the app's page in the Google Play store, it says that the app is not installed on my device. So I click "Install", and it downloads fine, but gives an error message once it starts the actual install. Please help me fix this problem and to continue on enjoying your app.

Thanks in advance! -Quinton
