Firefox and RealPlayer: Linux Download for Personally Owned Computers

Browse the Web with Mozilla Firefox, a Web browser that includes advanced security features and protects against pop-ups and spyware.

Note: This software can be downloaded multiple times and does not limit the number of downloads.

Video and music files often use the RTSP protocol, using a URL prefaced with rtsp://.  Firefox does not know how to handle this protocol natively. This can result in the error RTSP is not a registered protocol when you try to access streaming media on the web.

To adjust the Firefox configuration settings to allow Firefox to open RTSP links:

  • Open Firefox, and type about:config in the URL bar.
  • Right-click in the main window and select New and then String.
  • Enter network.protocol-handler.app.rtsp for the preference name and click OK.
  • Enter /usr/local/RealPlayer/realplay and click OK.
