Firefox for Android Support Forum

I access Outlook through Firefox. I added the site to my home screen to login faster. After proceeding through the login screen and accessing my email, I have a blank permanent bar on the top of my screen (where the website controls exist when the quick app starts up). My screen is shifted down from this bar, with elements no longer appearing at the bottom of my screen (calendar, etc). Buttons on the bottom of the screen no longer appear (they are cut off). I want my screen to not be cut off on the bottom. As an aside, the bar on the top of the screen is annoyingly thick whether it's loaded or not.

I can't switch between my work Gmail and my personal Gmail account. My phone simply shows a continual "getting messages____" thing. Could this be because I'm not using chrome?
