Verry helpfull Addon (mandatory for KDE users) Rated 5 out of 5 stars

One of the main needed Firefox Add-Ons if someone uses KDE!
Many thanks to Guillermo for this nice and helpful tool and I would spend some money to him - but I never create a PayPal account while discontinuing the license agreements.
