    Hello Nolan and all,
    
    There is unfortunatly no general way to determine if Orca is running
    or not.
    
    Firefox and probably Chrome are checking if
    org.a11y.Status.IsEnabled is present, see this commit message for
    details: https://mail.gnome.org/archives/commits-list/2011-August/msg06285.html
    
    Orca is setting this flag when running the first time and the ezoom
    screen magnifier too but it doesn't imply Orca runs at the time of
    checking. The only way to ensure Orca is running is unfortunately
    checking process, other way could work but couldn't. You could try
    by yourself, launch Orca, check org.a11y.Status.IsEnabled, kill orca
    and check again. Orca couldn't disable isEnabled after stopping
    because it couldn't know if there is another assistive technology
    enabled.
    
    Best regards.
