Where are ant.com files stored?

[jbnimble]

Using Ubuntu 14.04 and Firefox and Ant.com

Where are the Ant.com files stored?
They are NOT in Downloads or Downloads/Ant Videos
I rename these files; does that make them invisible? They still work OK in Ant.com

Should be where-ever FF saves downloads, believe it's Ctrl and the + key to see
