Sorry if this is a duplication – haven't found the issue in Ideas or Discussions. I use dual monitor setup and three virtual desktops in my Linux box. Primary for work, second for communication (Thunderbird, Slack etc) and the last one for background music and other stuff not related to work. Some time ago when I was starting laptop all Firefox windows were opening on monitors and virtual desktops they were before I turned laptop off. Same behavior when I was restarting the browser to apply updates. But some time ago all windows started to appear on primary screen – both on fresh boot and on restart to update. I am not sure whose responsibility it is. Could be related to desktop software, though my Openbox is not receiving updates for years. May some other X.org-related software bear the responsibility? But if this is related to Firefox, guys, please bring this feature back 🙂
