Could you try if that's an issue also on Ubuntu/GNOME? Could be a problem in your desktop environment rather than firefox (especially if other software do have the issue)

When I exit fullscreen the firefox window returns to the way it was before I hit f11&click-fullscreen I moved window to DVI-0 or left-display with video still streaming, hit <F11> & watched briefly, then hit fullscreen & watched again briefly. All was great, then exited fullscreen (same if I hit <ESC> or click the exit-fullscreen icon) - at this point the window zooms to a maximized state of DVI-1 It only seemed to do this when the firefox window was maximized on DVI-0, if I shrunk the firefox-window to use less than full-display before hitting 'fullscreen' or 'f', it returned to prior-case and just exited the video fullscreen display. This issue is cosmetic, operation did not stop working at any point, and it just required me to re-drag my window to my desired display. (If i noticed this before (I believe I have), I may not have recorded bug, just noted it on QA-test comments) ProblemType: Bug DistroRelease: Ubuntu 19.04 Package: firefox 65.0.1+build2-0ubuntu1 ProcVersionSignature: Ubuntu 4.19.0-13.14-generic 4.19.20 Uname: Linux 4.19.0-13-generic x86_64 AddonCompatCheckDisabled: False ApportVersion: 2.20.10-0ubuntu21 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: lubuntu 1784 F.... pulseaudio BuildID: 20190214235031 CasperVersion: 1.402 Channel: Unavailable CurrentDesktop: LXQt Date: Mon Feb 18 07:02:30 2019 Extensions: extensions.sqlite corrupt or missing ForcedLayersAccel: False IfupdownConfig: # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback IncompatibleExtensions: Unavailable (corrupt or non-existant compatibility.ini or extensions.sqlite) IpRoute: default via 192.168.15.19 dev enp0s25 proto dhcp metric 100 192.168.15.0/24 dev enp0s25 proto kernel scope link src 192.168.15.198 metric 100 LiveMediaBuild: Lubuntu 19.04 "Disco Dingo" - Alpha amd64 (20190217) Locales: extensions.sqlite corrupt or missing PrefSources: prefs.js Profiles: Profile0 (Default) - LastVersion=65.0.1/20190214235031 (In use) RunningIncompatibleAddons: False SourcePackage: firefox Themes: extensions.sqlite corrupt or missing UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 04/30/2008 dmi.bios.vendor: Dell Inc. dmi.bios.version: A10 dmi.board.name: 0DR845 dmi.board.vendor: Dell Inc. dmi.chassis.type: 3 dmi.chassis.vendor: Dell Inc. dmi.modalias: dmi:bvnDellInc.:bvrA10:bd04/30/2008:svnDellInc.:pnOptiPlex755:pvr:rvnDellInc.:rn0DR845:rvr:cvnDellInc.:ct3:cvr: dmi.product.name: OptiPlex 755 dmi.sys.vendor: Dell Inc.
