Package: firefox-esr Version: 60.9.0esr-1~deb10u1 Severity: normal Dear Maintainer, Using LXDE with a dual-monitor setup on laptop via LXRandR.
Steps to reproduce: 1. I have the External VGA monitor set up as the left monitor, i.e. this monitor functions as the main monitor with the taskbar. 2. Opening firefox and moving it to the laptop monitor on the right. 3. Play a youtube video and click to open it on fullscreen. 4. Press (esc) to exit full screen. What happened: Entering fullscreen the video played on the same monitor as expected but upon exiting the whole firefox window with all the other tabs that were open has now shifted to the left external monitor meaning that I have to drag the window back. What I expected: That upon exiting full screen, firefox would stay on the same monitor. I have tried mpv and mplayer and both return to the original monitor screen as expected. -- Package-specific info: -- Addons package information -- System Information: Debian Release: 10.1 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-6-amd64 (SMP w/2 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages firefox-esr depends on: ii debianutils 4.8.6.1 ii fontconfig 2.13.1-2 ii libasound2 1.1.8-1 ii libatk1.0-0 2.30.0-2 ii libc6 2.28-10 ii libcairo-gobject2 1.16.0-4 ii libcairo2 1.16.0-4 ii libdbus-1-3 1.12.16-1 ii libdbus-glib-1-2 0.110-4 ii libevent-2.1-6 2.1.8-stable-4 ii libffi6 3.2.1-9 ii libfontconfig1 2.13.1-2 ii libfreetype6 2.9.1-3 ii libgcc1 1:8.3.0-6 ii libgdk-pixbuf2.0-0 2.38.1+dfsg-1 ii libglib2.0-0 2.58.3-2+deb10u1 ii libgtk-3-0 3.24.5-1 ii libhunspell-1.7-0 1.7.0-2 ii libjsoncpp1 1.7.4-3 ii libnspr4 2:4.20-1 ii libnss3 2:3.42.1-1+deb10u1 ii libpango-1.0-0 1.42.4-7~deb10u1 ii libsqlite3-0 3.27.2-3 ii libstartup-notification0 0.12-6 ii libstdc++6 8.3.0-6 ii libvpx5 1.7.0-3 ii libx11-6 2:1.6.7-1 ii libx11-xcb1 2:1.6.7-1 ii libxcb-shm0 1.13.1-2 ii libxcb1 1.13.1-2 ii libxcomposite1 1:0.4.4-2 ii libxdamage1 1:1.1.4-3+b3 ii libxext6 2:1.3.3-1+b2 ii libxfixes3 1:5.0.3-1 ii libxrender1 1:0.9.10-1 ii libxt6 1:1.1.5-1+b3 ii procps 2:3.3.15-2 ii zlib1g 1:1.2.11.dfsg-1 Versions of packages firefox-esr recommends: ii libavcodec57 7:3.4.3-1 ii libavcodec58 7:4.1.4-1~deb10u1 Versions of packages firefox-esr suggests: ii fonts-lmodern 2.004.5-6 ii fonts-stix [otf-stix] 1.1.1-4 ii libcanberra0 0.30-7 ii libgssapi-krb5-2 1.17-3 ii libgtk2.0-0 2.24.32-3 ii pulseaudio 12.2-4+deb10u1 -- no debconf information
