Hi

You should be able to find files that you have downloaded in the Downloads folder on your Android device.

That is what I thought but they are nowhere to be found... I have found a way to play them tough, Tools>Downloads -- the odd thing is that I can't even find them searching for them on the device and in download or any other folders... It's like they are in an in-between world, in this existence only accessed through Firefox directly! Anyway, thank you for taking the time, Seburo.

Ok, glad to hear that this is resolved.
