It shows up when I run Firefox - in both about:plugins and about:addons -> Plugins If you use a central Mozilla autoconfig file setup - see, for example: <https://developer.mozilla.org/en-US/Firefox/Enterprise_deployment#Configuration> then you can use the following line to disable this plug-in: lockPref("plugin.state.librhythmbox-itms-detection-plugin", 0); (and similar lines to disable any other plug-in) James Pearson
