It just monitors Firefox download manager, dumb app

It doesn't work very well under Queue Mode. I set it only download 1 file at a time, but there are often 2, sometimes even 3.

Unfortunately, there is no function to download links in a selected fragment of a web page or on the entire web page, with filtering by extensions. There is no way to save a link to the original location of the file in descript.ion. Or better yet, a description of the downloaded file added by the user.

the download speed still is way slower than downloaders like IDM and also there is no options to customize it.

It said to put in the urls of the videos. I did. I clicked to download and it downloaded them so fast that I knew it hadn't downloaded anything. I clicked on one and the computer couldn't open it because, duh, the file extension was "file" and there wasn't really anything there.

I was loving it and I do still love it 95% of all times. It has some bugs that need to be resolved (see other reviews), but the developer has been vanished. So, this is a zombie.

I removed this addon.

Some sites like virustotal.com is not working as Sopor said below, and some sites require multiple attempts to load. so, I recommend remove this addon.

no option to auto-rename downloading files. with mask or simple (n+1)

view. +-. have seen more ugly

If enable some sites won't work. One of them that won't work is virustotal.com
I did found a work around. Add virustotal.com to "Hide Download Bar on following web pages".

Very useful except for one big flaw: no option to disable the confirmation window when you open a file. I clicked on it, yes I want to open it, you don't need to waste my time with a pop-up window.
