This add-on can:
Access your data for all websites

PRO UPGRADE : Since Youtube no longer provides direct download links for 1080p and MP3 qualities these two qualities require server infrastructure for processing, therefore user needs to Pay and Upgrade here >>>, you have the choice to pay whatever you want for this one-time upgrade which helps me keep this service alive for all users.


Why does it want your user data from all websites?
It requires pay upgrade. although it says it can be any amount you want it forces you to pay $30 to upgrade it.

If you just want to download mp3 there was another one in the addon page that requests your info from ONLY youtube.com, is completely free, two easy clicks to download the vid as mp3 and works well. Won't name it but it's on the same list.

Some one thought it was fine to put up a red banner that cant even be closed or removed from Youtube screen to affect our youtube experience just because they can .... like your plugin aint working with experimental youtube interface but why the heck you have to affect my youtube experience for it? My videos and suggested videos even load because of this stupid red banner of yours....uninstalling right now...

Потраченее время

При просмотре, именно просмотре почти всех видео вылезает на четверть экрана табличка "Это видео в новом экспериментальном формате и я не могу его сохранить" и ее никак нельзя убрать. Т.е. с этим плагином не только скачать видео не получается, но и даже нормально посмотреть.

No 1080p download for free

its good

Requires a pro upgrade for what others do for free. Better off using another one instead.

Getting this error when clicking on "Install" button:
"this add-on could not be installed because it appears to be corrupted in mozilla"

Need pay, not free
