@Schtritoff: I have discovered that your solution works as long as I don't close my Firefox browser too often. There is a fix for this when it happens, just install the GM NG installation file again into your Firefox and close your browser and launch it again. It works, at least for me. Just remember, closing the browser (from time to time) damages the addon's installation and you will have to install the GM NG addon again.
