While doing a browser fingerprinting survey, I was quite surprised to

The culprit is
/usr/lib64/mozilla/plugins/librhythmbox-itms-detection-plugin.so
It appears that whoever maintains the rhythmbox RPM has chosen not to
package the browser plugin separately like it probably should be. So if
I have the rhythmbox RPM installed, I have the plugin.
This is rather worrisome because I can find no trace of the plugin in
the Mozilla preferences panel, so if it is there it is very well hidden
and if it really isn't there, it can't be disabled there.
Is there some kind of blacklist file I can put in
/usr/lib64/mozilla/plugins/ or ~/.mozilla/plugins/ to specifically tell
FireFox not to load that plugin, or do I have to uninstall rhythmbox?
Thank you for suggestions.
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)
