Nom: Firefox Version: 83.0 Identifiant de compilation: 20201126174332 ID de distribution: archlinux Agent utilisateur: Mozilla/5.0 (X11; Linux x86_64; rv:83.0) Gecko/20100101 Firefox/83.0 Système d’exploitation: Linux 5.9.10-arch1-1 #1 SMP PREEMPT Sun, 22 Nov 2020 14:16:59 +0000 After enabling gfx.webrender.all (value true in about:config), there is no more tearing in web sites like google street view. But all my extensions, while working, offer an empty dialog pop-uo when I left click on their icon in Firefox main bar. UBlock origin, HTTPS Everywhere, Privacy Badger or Joplin all act with the same behavior. See screenshot. If I disable gfx.webrender.all all my extensions dialogs are back. I had gfx.webrender.all set to true before version 83.0 of Firefox and my extensions were working fine.
