Well, it's damage. This addon doesn't work with several addons (e.g RequestPolicy etc). Some many values stay instead to be deleted.Also, this addon is very poor. There's only a few features. For example, you can't see which values in about:config will be removed by this addon...It's can be dangerous, if you don't take care.
At least, I find a solution which consist to edit the pref.js file in the Firefox profil. This addon doesn't allow to do that too...
Also, I advice you to correct/change the name of the .xpi file. In the profil, it's not easy to determinate which file is the eCleaner addon. Instead of eCleaner.xpi it's something like that :"{c72c0c73-4eb0-4fb3-af0f-074e97326cfd}.xpi". It's very practical...Some developers take care about that and some many users enjoy this.
