This extension works more often than not, but sometimes things from third-party advertisers download things such as the Opera Browser without asking, and keeps asking for you to allow notifications after saying No to them. The only way sometimes to get out of the third party mess is to close, then reopen the extension and try again. I can get 1080P on this extension where most apps either don't work anymore, or only capable of downloading in 360P. I will still use it, unless IT too stops working because YouTube blocked it, or whatever causes the other extensions to break. 03/2025: Doesn't work half of the time now, takes you to a lot of adult websites , and I keep getting virus warnings. Maybe it will download the first 22.5 MB of a twenty-minute video now. 03/20/25: Takes you to a fake Microsoft Virus Warning page, and won't let you click out. I wouldn't give my name or a nickel for Premium to anyone who would do business with such sleazy third parties just to make a Buck. I wouldn't trust them with my info as far as I could throw them, and couldn't care less about their rationalizations about it either.
