I do not know how to use

On a page of archive.org links direct to mp3 files, it sees not one of them. It has no way to define the download directory or choose each time.

Way too much of a good thing! DownThemAll shows a list of *all* recently accessed URLs, many of which are indistinguishable from each other because they are truncated in DownThemAll's popu dialog. I want something to download *only* from the *active tab* in Firefox!!!
Unfortunately, I don't find any way to limit DownThemAll accordingly, neither in the options, nor by revoking unneeded permissions.

Great download manager if you ever thought FireFox's build-in download was too good and you want something more unstable which will makes you restart your downloads from zero again and again over the smallest bitrate drop...
Run away from this add-on

リンクをクリックしても起動せずデフォルトのダウンロードしかできない

Расширение ничего не скачивает кроме картинок и тому подобных файлов. Ни с одного сайта не смог скачать видео, каждый раз выдаёт ошибку. Бесполезное приложение. Улетает в помойку в след за DownloadHelper.

ver4.4でマネージャウィンドウの表示位置がおかしくなった上に拡張子を付けてくれなくなった
ver4.3のほうが圧倒的に使い勝手が良い
ver4.4>★☆☆☆☆　ver4.3>★★★★☆

Not only complicated for nothing, but also it does not work despite many trials and errors. I am not sure why it is recommended by Mozilla.

This addon doesn't work. No value added to download flies.

No longer possible to specify download location / folder

Used to be able to break large downloads into smaller parts, and they would all download concurrently. And if the internet dropped out it would simply save what you had and then you could resume. I'm aware of the issues with the new firefox, but I just don't think there's any point to this add on without this feature as it doesn't do anything the built in downloader does now

ne fonctionne pas , s'ouvre puis ce ferme zero a revoir totalement

once if the download pauses or the internet goes off for some seconds. all the download data is lost and the download starts from beginning.
