Hi, it's bizarr, but my Firefox v 115.29.0esr does not show all opened windows in the window. Example: I have 9 windows open, and each windows with different amounts of opened tabs. Firstly, when switching with "cmd <" from window to window, it does not show all windows in the "Window"-menu. Sometimes it show 3, sometime 1, sometime 7, sometimes no other window in the window. But the windows menu should show all opened windows in each window. '''Can someone explain that?''' Is there a setting somewhere in preference ? I had created a pdf with 9 window screenshots, which shows the problem with super clarity. But unfortunately this community message form does not accept pdf ! It would be best imo if the windows menue show all opened window and in plus for each window also the tabs open in each. Thanks ! PS: am using MacBook Pro mid 2012 with macOS 10.14.6 Mojave
