I am using Firefox 47.0 on Windows 7. When I started the Slingbox Application in Firefox, I received the notice that there was a new Sling Player web plugin. I accepted the terms and conditions and the program went to Newwatch.slingbox.com to download the new plugin. I clicked on "Allow" to permit the download to happen. When the download completed, I received the message "The add-on down loaded from this site could not be installed because it appears to be corrupt." Is there another place to get this download? Do I have any other options?
