How to uninstall an unknown addon/plugin/program
A couple of months ago I saw a add on? plug in? which lists the companies (like Doubleclick) that are tracking me as I browse. I installed it and it took over the right part of my screen with a list of trackers. I now would like to get rid of the tracking, but I don't know what it was called. I don't see it under the list of add ons or plug ins, nor in the control panel under the list of installed programs. *4.0.60129.0 listed below is apparently a silverlight plugin
Any idea how to get rid of this thing without remembering its name?

As you suspect, 4.0.60129.0 is the Microsoft Silverlight plugin.
As for the add-on, you appear to be describing the Ghostery extension. For details of how to uninstall it, see the section on uninstalling extensions at https://support.mozilla.com/kb/Uninstalling+add-ons
