i don't use firefox. i use opera and i looked at the extinctions and there's nothing there that i see would work, might be missing or overlooked. But what about the .flv files, converting them as the dl, more then one dl at a time? yes i've heard about dl managers, but never dealt with them before either and doing 16 things just for one file is far more headaches then i like to piss with.

i know yt dl pro 3.6 or 3.8 does all that, but i need the code or a cracked version. i've used the standard yt dl before and it works, i rather just dl it in the form that i choose and be done with it.
