My android tablet secondary display doesn't work when opening firefox.
When I open firefox on my tablet the secondary display goes full screen. I can see the web page and nothing else. I can't see the menu bar or the web address or the tabs. I can't even see the tablet 'menu' at the bottom or the mouse arrow. It does not do this to the tablet's display, only the secondary display I have connected via hdmi. No other app I have does this, or has any issue similar to this. The issue also does not occur 100% of the time, more like 85-90%. And it does not matter what website I open. I can open firefox with no page open and the secondary display still automatically goes to full screen. If I look at the tablet screen and minimize firefox or hit that square button the secondary display automatically goes back to normal and produces the entire screen. But as soon as I click back on firefox it goes back to like a full screen web page display only. This completely defeats the purpose of using a secondary screen and since I can find no options to stop this from happening and because it seems to be completely random it's driving me insane.
