After installing Realplayer using Synaptic Package Manager,
Open a terminal and type the following commands:

sudo mkdir /usr/lib/mozilla/components
sudo mv /usr/lib/mozilla-firefox/plugins/nphelix.xpt /usr/lib/mozilla/components/
sudo rm /usr/lib/mozilla/plugins/nphelix.*
sudo cp /usr/lib/mozilla-firefox/plugins/nphelix.so /usr/lib/mozilla/plugins
