Hi PowerApps team,
I noticed that when an PowerApp is opened in Firefox it always loads it a little bit too big for the screen.

It adds a vertical scroll bar and you have to scroll down to see all contents:

Meanwhile, loading an app in Chrome it loads perfectly fit for the screen:

I have tested this with 3 different users and 3 different screens. It always loads perfectly fit in Chrome and always a little bit too large on Firefox. Even if you don’t use full screen browser and resize it to any side it will load perfectly fit in Chrome and a little bit too big in Firefox.
Unfortunately, in my org we are told to use Firefox for everything and users get annoyed that PowerApp loads to big and they either have to keep using scroll bar or zoom out in the page (however, even if you zoom out and reload it will load it unfit again since PowerApps always tries to fit the app to screen even zoomed. So every time you load you have to zoom)
Is this possible to fix in future versions of PowerApps?
