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.

It has some bugs that need to be resolved (see other reviews), but all in all I love it!

Pls, add the option to change button color.

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
Please fix all bugs since last release that was almost 2 years ago!

Instalé la extensión únicamente para resumir descargas incompletas. No funcionó. Desinstalé. Califiqué.

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.

This works well and is helpful altogether, BUT I'd really prefer if it were possible for it to be put on a separate bar without it having to append code to every page.
I know this isn't this extension's fault and a limitation that came with Mozilla's transition to WebExtensions..
The appended bar sadly overlaps the URL tooltips when they're shown at the bottom of the page as well (which is the default behaviour for Firefox).

Also, it's missing an option to disable the dialogue that pops up whenever a file is opened or executed directly from the bar. The dialogue counts as an actual window that is then added to the list of closed windows. We should avoid that.
