Stay away. Large downloads spike RAM usage while finalizing, causing the files to fail and your PC to freeze.

good

lifesaver extension if you want to avoid installing extra software on your ubuntu/windows machine

Everytime I try to download anything I got a server error message and I have to manually resume the download because the retry system doesn't even work.
Trash.

this works well but is currently taking up 30gb of space in C:Users\{user}\AppData\Roaming\Mozilla\Firefox\Profiles\{Profile}\storage\default\moz-extension+++d0d1ae06-7b71-4a82-a0b8-718068b15730 and i dont know what i can delete from there

doesn't work. nothing happens after pop up download window

非常好用，可惜edge没有

It works, but... there's no way to use custom download locations, because /Downloads (my default location on Firefox under Debian Linux always is chosen.
That's a bad habit, because very often I use custom storage locations like USB HD's and especially bigger downloads put a high load unnecessarily on my SSD, which otherwise could be re-assigned completely.
Furthermore this AddOn seems to be dead, as there was no update since 2 full years... and there are numerous open tickets visible.
To clarify: I will re-edit this review in _ a n y _ case (dead or alive) and will downgrade it in case of a dead project and no response, so that it becomes at least obvious, that one should consider to remove this more and more function-wise dying thing from Firefox.

Excellent! It would be even better with an icon for the new Firefox sidebar :)

Çok hızlı indiriyor!

This add-on supercharges Firefox's built-in download manager by enabling multi-threading support. With no additional software required and a robust set of options, this add-on is fantastic. Thanks to the developer!

It's good but fails for very large files, ie 20GB or more. After the download, firefox starts saving it, but it gets stuck halfway.

Works perfect

This is a very good extension, it's very useful and can increase the download speed by a lot!
