this is the most useful plugin for Firefox you can find

⬇️Multithreaded Download Manager
Download manager with multithreaded support.

Расширение отличное.Добавьте,пожалуйста,функцию загрузки торрентов.

besser als Free Download Manager

Thanks :-)

Very good, reliable and handy downloader. I love that it resumes and continues later a failed download.

This one looks like idm very much,but it's free! Really nice.
