Junk. Failed to download every video I tried it with (if if was even attempting to download them at all, which is dubious). What it did instead is put up a spam popup for something called "downloadytb", or an empty popup in some cases.

「接続がリセットされました」じゃねーよゴミ

Вообще не работает.

CLICKBAIT.... you just gtant permission to report your internet activity but doesn´t work as announced

I couldn’t figure it out.. I'm using udl helper, installing it was easy and fast

Нет меню....

Does not work. Right clicked the blue down arrow as instructed, up popped another firefox window, then a blue bar appeared on that page saying "loading".....forever, it never loaded anything. Sorry, I'm not waiting some undetermined amount of minutes or hours waiting for a video to load that I could have watched 5 times before it ever loads, if it ever loads at all. Apparently Youtube has done something to make all the youtube downloaders break. Not a single one I've tried has worked. All my apps and os are fully updated

Rightclick icon doesn't appear

No funciona :(

ne marche pas
