@James , there is a strange behavior when I right click the AnyDVD tray and choose to open the Redfox web page. Same behavior on 3 computers with Windows 1903 both 32 bit and 64 bit. Firefox is already running an previously a new tab was added after doing this. No issues before with 1809. A window opens and says: Firefox wird bereits ausgeführt, reagiert aber nicht. Der offene Firefox-Prozess muss beendet werden, um ein neues Fenster zu öffnen. Firefox is already running but doesn't react. The open Firefox process must be terminated to open a new window. It's not really a big tragedy but just inconvenient.
