Clean Uninstall
"Clean Uninstall" cleans fingerprints (such as preferences) left by an add-on from your Firefox profile upon its removal. Usually add-on developers do not clear preferences created by their extension just before extension gets uninstalled. This leads to have a massive pref.js file once you have tried a few extensions. So after trying out a few extensions, although you have removed them, but your Firefox is not as responsive as it used to be. This extension notifies you about these preferences after an extension got removed.
