Realplayer Plugin RP Callback Helper

[appi2]

Just been using the dom inspector in FF to check some javascript on a page of mine, noticed a script not part of my own.

It starts function __RP_Callback_Helper

It's the Realplayer plugin for firefox that allows you to download flash videos to your pc.
Disable the plugin and it disappears.

Just thought I'd post incase anyone else goes through the #*$! is that.
