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.

لابئس

Looks more like advertisement for a windows app than an actual video downloader. Can't even do youtube...
