It doesn't download any faster than base firefox, totally useless

真的很好用，输入链接就可以下载了

Works perfectly with or without using the manager. My only critique is that the 'extract media links' feature doesn't always work with download redirects, but it usually isnt a problem.

It doesn't intercept browser download hence the multi-thread download isn't so easy to use

It has almost no options for control over functionality or behavior.

It is nice and efficient, well planned and the options seem right enough to avoid cluttering the UI or complicate usage.

Fonts seem small in my 27" 4K monitor compared to other in browser UI elements. The theme although clean is a bit painful on my eyes and doesn't follow any hints from Firefox's UI either.

It integrates quite nicely with FF's "YouTube Video and Audio Downloader" add-on.

It won't let you change the number of threads and it doesn't download any faster than base firefox. A waste of time. Moreover it asks too many permissions, very suspicious don't even install this except if you have no valuable data on your system.

It doesn't download any faster or better than the standard download through Firefox! Rubbish!
