Tut nicht im mindesten, was es soll, trackt mich gleichzeitig, soweit es nur kann. Nicht zu empfehlen, sehr unseriös.

not support 1080p

nice service

Very good, works as expected! Developer is light fast in replying in case of issue.

it a nice app

我付了两次费，不但没退款还是依旧下载不了720以上

Do not use addon. It is a scam. I donated to get the pro version and it worked for a little bit then stopped. Tried contacting the author multiple times with no response. It seems like the app is a bait and switch, works long enough til you can't refund the donation then stops. Beware.

You need to be a PRO member or some sort to enjoy the services. Trash.

Garbage dev. Every year he finds an excuse to make you repay for it to work properly. He has enough of my money. Reporting for abuse. I suggest that the rest of you do the same. He needs to be held accountable. There are other extensions that working properly and for FREE at the Chrome store. No need to use Firefox any more since it's just a Chrome clone now.

Over half their features are 'pro only' and they point blame at YouTube.
