Good software really use full

Does everything I want efficiently and quickly. I really hope this developer stays the course with their software and extensions because, so far, they're doing everything right.

Can't beat this software, superfast downloads compared to firefart default downloader, and you can resume also. And it's free !

I really want to give this more stars but I can't. I have have two major complaints about FDM. First, a bit minor, is that this extension needs a way of either bringing the download manager to the forefront, or at least a notification that your download has began. Second, and is a major for myself, is that the extension completely bugs out comments with youtube for some reason. If you use youtube and comment/reply regularly, you'll find yourself disabling this extension to prevent comments from posting duplicates.

Hi, developers, here I found some problems,

1.When I sent a comment on YouTube, it exactly sent multiple time, it made me like a bot

2.Another problem happened randomly when I was watching Youtube (mostly I was playing my music list). Usually, I noticed it because my PC had been stuck, and the disk usage was almost 100%, and OS popped out a windows said Firfox is no response, I forced Firefox to close.

The followings are my spec:
CPU: intel i5 8400
GPU: Nvidia Geforce GTX 1050
ram: 8G
HDD: 1T, no SSD

Now, I have disabled the addon, and ererything is fine.
Firefox 75.0 64-bit on Windows and FDM 5.1.38.7312(79f26aa)

Works for every kind of downloads including torrent, its lightweight and its fast, what else do you need
