These people do the best job of keeping up with the big Y and some other sites that make it difficult to download stuff. They have the most responsive support I have ever experienced. I have worked with computers since the 1960's but this new stuff confuses me. They have been patient with this old guy, and their price for their programs is very reasonable even to someone living on social security. I mainly wanted videos, but full program downloads almost anything you ask it to download and seems 10 times faster regular downloading. It automatically saves it on your drive and provides a direct link to access file location. I am using an HP Pavillion of 2008 vintage and have several thousand files on my drives. I have had problems with this extension which only works sporadically in FF. Kick loose a few bucks and buy the main program license. You will be happy you did. They have fixed the AntFF downloader!
