Good evening, I tried to download the Add-On AdBlock Plus for GNU IceCat 3.0.7-g1 but it says that it cannot install the plug-in because IceCat can't verify the Author of the software.
The installation of the plugin works very well from another site, http://www.extenzilla.org/scheda_estensione.php?id=472 , in fact it doesn't appear any error message.Hoping you read this mail, I look forward for a suggestion from you.
