Comment 3 for bug 1969307

This has been happening to me since 21.10. I wanted to add that I have the Firefox launcher as a favorite in Unity which as far as I can tell remains in place consistently. However, Firefox sessions, which I believe are what this bug report is targeting, do disappear at times. I have attached two screenshots, one of which shows my screen with an open Firefox window open but no orange dot in Unity reflecting that. The second screenshot shows the tab moved to a new Firefox window and the orange dot returns (but the orange dot will go away if the tab is moved back to the original window).

As another piece of data, if I have multiple Firefox windows open and scattered across virtual desktops, while initially all the Unity launchers on each desktop have one orange dot showing the presence of an active Firefox window, when the bug hits then all the orange dots on all virtual desktops go away (unless of course I launch a new Firefox session).
