It is a paid addon. And even then they don't offer you 1440p or 4K resolution. 480p is missing.
360p is available in the free version, but it didn't work for me (got an error).

Download it. Try to use it. Get a message that it won't do anything unless you play for pro. Scam.

It used to work well, but I have been trying to use it to download videos, but it doesn't work anymore. I have removed and and re-added it, restarted my browser and everything. I still get the "failed download" error.

не работает

Easily the best downloader add on. Easy to use and works great. I've used it for years with no problems.
