It seems in the past few months the dev's have been trying to update the add-on, but it's become worse in the past 6 months. Filtering no longer works as it did a year ago. Errors on 90% of downloads, so it won't save the file. File Naming now adds % instead of _.

You need a STOP / CANCEL option on your icon!

"Error: filename must not contain illegal characters" just rename it.

worthless program.....can't contact the person that created this add-on......thought I love it but video's do not download in what it claims to be.....loath people that assume everyone is a know it all in technology and can not realize some people just not get something or how to work it.....damn you got to love ignoring morons

通常のダウンロードと変わらない、再開等設定してもされない

This Program is obsolete, all it can do is show you the thumb nails of pictures on multiple websites I tried it on. Which I don't need a program to do that I can just right click and do that. Explains why it don't show the Image size on it it either. Not to mention it took away to copy any ability on the program to copy the urls. Just another obsolete relic add-on of Mozilla past.

Muito completo.

I used to run a much older version of this on Firefox 50-something. I preferred the interface since it would open up a separate window I could move to one side and keep an eye on downloads as they progressed. Now I have to keep on switching tabs. Maybe that's just a web extension thing, but I miss it.
My main complaint, like others, is there is no way to designate where to send downloads other than a sub folder in my Downloads folder. I use other extensions that download files provide a save to window so I am not clear why this one does not anymore. I still use the extension regularly, but not as readily as I used to unless I really have a lot of files to download at once.
There also used to be a feature where if I had a save file widow in Mac Finder that it had a selection to use DownThemAll to handle the downloading. That again meant I could monitor the download in a side window if it was something slow to download.

Used to be better. Read the 1* reviews for details (even though I disagree with their 1* rating). Unfortunately, some of the step-backs are due to changes in browser developers permissions policies.

Absolutely essential extension. Batch downloading is a huge time saver. I miss the option to remove duplicate links, which was available on the extinct XUL version. The option to view/edit the entries is also missing, so a broken link cannot be reviewed nor fixed.
