Just a minor problem. Some web pages have important data in the last line at the bottom of pages. Download Manager blocks the view of this line and has to be closed to see what is there. Not a big deal but a nice improvement if you can avoid it.

I don't know why and how but it causes virustotal page bring captcha test infinitely

This is a god sent. Makes using firefox so much better :)

Неплохой но все-же не хватает функции возобновления "прерванных/прерываемых загрузок сайтом"(Не пользователем) или-же из-за нехватки скорости.

Does not work on ff, useless.

This addon prevents the virustotal site from working and possibly others according to another reviewer.

One workaround is disable this addon from working in a private window then open a private window to use virustotal's site.

But I don't like addons messing with my ability to browse websites. I'll be looking for another download manager addon.

List of files from manager is gone after restart but is shown in firefox manager. List of downloaded files still appears on bottom of FF even i closed it at least 10 times.

This downloads the file but is very lacking.
The download starts when you right-click the link.
You are given no opportunity to rename the file
or select where you want the file saved.
===========================
I discovered that: under 'Files And Applications,'
setting Downloads to Always Ask fixes this issue.
