For years, this add-on has required an additional program to installed. No problem. But the program has never installed. Not once. Not for several years. This add-on does not work, has not worked and probably never will work.

It asks for money to do anything.

Anyway I would never install it in my main browser, because its code is secret and it can see all my passwords and other things that I write.

See:

https://support.mozilla.org/en-US/kb/permission-request-messages-firefox-extensions#w_access-your-data-for-all-websites

"The extension can read the content of any web page you visit as well as data you enter into those web pages, such as usernames and passwords."

Absolute rubbish. Does not work until you pay.

very good

Me sirvió bien.

I have this extension on all my Mozilla browsers. Very reliable extension.

Doesn't work with YouTube -at all.
