I was skeptical of how the download speeds would differ from the defaults in Firefox, but WOW did this shock me... BLAZING FAST SPEEDS.

Incredible extension, so much so that I'd happily pay for it. Bravo, Jungyu.

One of the best download manager. I was downloading a file with 340 - 120 KB/s. And with this extension I was downloading with a speed of 3MB/s.
Es una extensión realmente útil. Ayuda mucho.

Easily the most polished DL Manager. 10/10!

靠谱，简约，方便~

the dummys who limit the download speed will now cry >:)

Exactly what the doctor ordered. This is the right stuff. Nicely done. Thank you!

WOW! Endlich ein guter Multithread-Download-Manager. EINFACH-SCHNELL-GUT! Keine Bergleitanwendung nötig. Vielen Dank an die Entwickler für diese Erweiterung.

Probably the only extension for FF which can hijack all kinds of download links, while also being non-intrusive. Thanks!

Works as intended. Easy to use and speed up the download a hell lot.

I haven't found an option to set a User-Agent though

修改线程后下载速度非常棒。
