** Description changed:

- I have the mozilla stable version installed using the mozilla binary
- method, and snap for the beta channel. The icon is broken, both in the
- menu entry and in the panel. That is, there is no icon in menu, and the
- generic cog icon in the panel.

  This is on 22.04 But I have the same problem in 23.10 and in a VM 22.04.
  That is, I can reproduce this every time.
  
  I did snap remove firefox
  
  to uninstall, but this file
  
  /home/tim/.local/share/applications/firefox_firefox.desktop
  
  remains.
  
  So I remove it manually, and reinstall.
  
  The desktop file for this is now:
  
  /var/lib/snapd/desktop/applications/firefox_firefox.desktop
  
  It is called Firefox Web Browser in the gnome launcher, and it has an
  icon. But after launching, it still uses the generic cog icon in the
  panel. The context menu from this icon has no actions, except to Quit.
  If I create a second window, both are associated with this icon, which
  is good.
  
  In the Gnome launcher, if you search for an app and if that app is
  running, the Gnome launcher indicates it with a dot. However, while this
  works for the mozilla binary, the icon of Firefox Web Browser does not
  show a dot, even though I have two windows from it open.

  Add
  this this line to the .destkop file, near the top, fixed it:
  
  StartupWMClass=firefox-beta
