I would like to use the Real Player Downloader addon that I could previously use with Firefox. It is not compatible with Firefox 5. How do I go back to Firefox 4?

Hello, If you wish to downgrade to Firefox 4.0, ensure that you have uninstalled Firefox 5.0 and any other version of Firefox you may have. A download of 4.0 can be found here.
