Nice tool. It seemed like nightlies default to Wayland, so I had to test with MOZ_ENABLE_WAYLAND=0.

Any suggestions there? So the following was tested back on my 104.0.2 (originally downloaded from https://download.mozilla.org/?product=firefox-latest- ssl&os=linux64&lang=fr ) : > Another interesting point would be if setting gfx.x11-egl.force- disabled (in about:config) to true helps with the issue. No. > Also, I suppose gfx.webrender.software:true works around the issue? No. Based on the bisection result, I also tried XDG_CURRENT_DESKTOP="". This changed the main issue but did not solve it. The window did not remain black, but it did not show firefox controls either. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1987976 Title: firefox black window Status in Mozilla Firefox: New Status in firefox package in Ubuntu: Confirmed Bug description: nicolas@nicolas-fixe:~$ lsb_release -rd Description: Ubuntu 22.04.1 LTS Release: 22.04 nicolas@nicolas-fixe:~$ apt-cache policy firefox firefox: Installé : 1:1snap1-0ubuntu2 Candidat : 1:1snap1-0ubuntu2 Table de version : *** 1:1snap1-0ubuntu2 500 500 http://fr.archive.ubuntu.com/ubuntu jammy/main amd64 Packages 100 /var/lib/dpkg/status When I boot Ubuntu and start Firefox, the Firefox's window is totally black.
