Hi Is it me or is there something wrong the display have changed and I cant play anymore as i cant see the whole maps i am involved in all the menu is now in the upper window and the maps under it but i cant see them totally
That's what I'm using as well, so that shouldn't cause too much trouble.
Maybe one of FF's recent updates changed some security features? Warzone uses the Canvas element for rendering of the maps, which by some websites is abused for tracking visitors. I don't know what level of Enhanced Tracking Protection you have set, but I have mine set at Standard. I you have yours set higher, maybe try setting an exception for ETP for warzone.com.
Have you tried opening the game in a private browser window in FireFox? Then you can see if any extensions are causing the issue. (Assuming your extensions dont also run in incognito mode.)
