I realize plugins are not part of Mozilla, but Mozilla is giving me a looping error message that something is missing when I don't see at all that anything is. I receive this message when I am trying to play an audio file for transcription. "Additional plugins are required to display all the media on this page". I know the program uses QuickTime, and that is up-to-date, but not sure what other plugins it would need. There is an "Install Missing Plugins" button. When I click that, a Plugin Finder Service window opens and the message "No suitable plugins were found".
