Truly excellent add-on. Really dislike that DTA asks for so many permissions it doesn't seem to need.

As the other reviewer stated, this isn't as intuitive as it could be, but I still give it 5 stars. For example, it took a second to figure out the "Fast Filter" is not a result filter but a selection filter. In other words, it selects according to your filter rather filtering out results that don't match. It's more intuitive to use some kind of selection boxes with a selection box above all results to click on which selects all, or somehow provide a method of using Ctrl+A. Took a second to realize you can just type an asterisk in the box to select all. Still an excellent add-on. Very clean. Very fast.

Very clear UI

The best "Download All" type extension, not bloated or overly complicated to use like others. Not as intuitive as it could be, so expect to spend a few minutes figuring it out. But once you do, it's good.

A very good extension. The naming mask option is great and useful.

For example to replace '%20' by " ", %2C by "," and %26 by "&" the following naming mask can be used:

${file|replace:/%20/: |replace:/%2C/:,|replace:/%26/:&}.${ext}

easy use
i like it

only works for images

Pretty good and efficient.
As noted by r.koegel, file names containing spaces or "#" (and probably other characters, but these are the two I've come across) are downloaded with "%20" instead of each space, which is somewhat awkward.
If you use Unix, the following script may help you (it sure helped me):
for f in "$@"
do
g=`echo $f | sed -e 's/%20/ /g;s/%23/#/g'`
if [ "$f" != "$g" ]
then
mv "$f" "$g"
fi
done

It's about as good as it gets right now. My only issue is that it apparently can't auto rename %20 and other placeholders to the 'spaces' or other regular characters in filenames. So downloading a file such as "this file.zip" becomes "this%20file.zip"...which is annoying when downloading 1700 text files from a server.

Perfect for me.
Simple interface, even my elderly father can use it to download media from websites.
Way better than all those complicated "powerful" extensions.
Thanks liebs!

It used to work with Tor browser, but the update to 8.5.4 broke the add-on. It does work properly with my VPN, however.

The issue with Tor is that it never downloads all selected files in all tabs and the number of successful scrapes is random.

The user interface is weird, ugly and confusing. There are many user-friendly alternatives out there. Avoid.
