Can't discern if a Firefox or Windows problem. My screen is stuck between two black walls and I can't figure out how to get out. It doesn't allow me to expand the screen or change browsers from the home screen. I sure hope you can help!!! Thanks!!!

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

This question is tagged as "mobile".

Is this about Firefox on a mobile device or about Firefox on a desktop device ?
