May I ask why you need to access our data for all websites since it's only supposed to work on Youtube?

Видео 1080 и больше - платно для скачивания. Лучше купить подписку на Youtube.

Half-Good, download some.

When it's available, it works like a dream, but it often vanishes from YouTube without warning for long periods. I have no idea why.

its a little bit scratchy

Firefox 48 - does not work
Mobile Youtube - does not work

I have not used this add-on in quite sometime, now they want money for a Pro version which used to be part of the original add-on.

Pulled the trigger on Pro. I'm on the fence. I get blocked IP a lot. I wish people would give up the ghost on doing this server side and do what another add-on did and just download both files locally and use a client app to encode them. Or just give us the option to download ourselves and I'll do it myself.

Paid PRO version currently doesn't work with Firefox v79.0. Worked perfectly for years prior to a few days ago. Working with Support to try to determine what is causing download process to stall. Will submit updated review when (if?) solution is found.
