Edit: New version 30 september 2019 (4.1.2) : now is good, is improved with new features asked and bug fixes, like the sound and the easy delete shortcut to delete completed downloads, furthermore i see a whole new speed improvements. Thank you.
Now i think you have forgotten a feature: the "Empty the download files list (of downloaded files, green color) when the main window is closed" . ------------------
Old comment:
This is not good as 3.0.8 dta! version in seamonkey, this has limitations, the download window is worse ( WebExtensions limitations i guess ). This has fewer options and features. Try the 3.0.8 version of dta! in seamonkey browser (2.49.5 last version of seamonkey) , it 's the old and best dta! there .
In this new version (4.0.11 ) the download window uses the download system of firefox quantum , try to download many .jpg little/medium files together , 4 files per time, it is too slow and it takes too many resources until almost a browser crash! and has many slowdown even with a fast 4 core cpus and 16gb ram .... THe same situations when you try to cancel or remove all the downloaded files in the log window, i didn't saw an option to remove them automatically and it takes too many resources. there isn't a sound when the download completes either too .. I loved dta! for years but this is new version has many problems, if will not be resolved i 'll continue to use the old version in seamonkey. sorry

Finally, Downthemall is back!! Thx
I have one question: How to change the download location? I dindt find anything
Regards!

used it for a while but the new update wants permission to view browsing history.

Never knew how great this add-on truly was until I no longer had access to it. Boy am I happy it came back! The interface is simple and straightforward to use. Most of the features and options are obvious. In short, the ease of use is what makes this app a huge winner when compared to others.
So happy you're back. I'll be contributing very soon.

FINALLY BACK! I appreciated this software, and wished ever since FF Quantum came out that DTA would work. So happy to see it installed this morning when I fired up FF. The alternatives were junky. This is the real deal!

In assoluto il migliore per scaricare PDF, MID o MP3 dai siti che mettono a disposizione i materiali per noi insegnanti di musica. Un grande ritorno! Grazie Nils e crew!

Bentornato, DownThemAll ci sei mancato!

So glad to see this return. It's been working as good as always.

The only things I've found myself wishing I could do is have completed downloads automatically cleared from the manager and being able to choose where downloads go.

I sent a little contribution, too.

Ist ist wieder da, fast genau so gut wie früher. Nur eine Sache stört mich etwas: Ich hab nicht gefunden, wie ich ihm sage wo er speichern soll. Alles nur nach Download machts unübersichtlich.

DownThemAll has been a necessary utility in my life for many years, so I am extremely happy to see it back in WebExtension form. Thanks so much, Nils!

Ive been waiting for SO long for this addon to return, truly the BEST addon for ANY browser and the ONLY download manager I ever use, SO HAPPY YOU'RE BACK THANK YOU!!

Muchas gracias por volver! Thanks from coming back! It's my favourite extension for downloading and I missed it!

One of the best FF extensions ever!
