It use to be a good add-on until recently that I got a tons of Antivirus warning about malicious website when I open the Add-on and click downloads
eg.

adsrv.me this one should be virus

around 81 warning per downloads

This a malicious addon. When you use the same , it connects with various malicious websites. Lucky that my AV caught and saved me from any damages to my data and computer

after using this addon, I got banned from many sites.

has some amateur bugs like lack of extension in saved images for which Firefox would normally automatically add extension, but this addon leaves file without, also gallery shows images filtered out by width and height as being selected in gallery, but removes them on reopening gallery...also author not responding or fixing issues, and advice for everybody, please use level 0 depth only, and other extensions like image max url if you need larger images, this addon is good only for currently loaded images in page as bulk saver, but not good for getting original images, has no smart recipes (rules)

Because of the way this works, it caused me to get locked out of my Instagram account the 1st time I used it. I have been trying for hours to get unbanned but from what I have read online, it should just be a temporary ban - as long as I don't use the offending 3rd party add-on again.
What a total POS!!! Do NOT use this extension!

It is very cumbersome, slow and does not even work, e.g. Chrome is there for the great "Image Downloader" - you should already have one :\

It doesn't work anymore as usual!

pas de choix pour le téléchargement : trop d' images enregistrées et un tri trop important à faire

Most of the time it is not picking up videos even after the full 2-hour finished playing. Today it flashes the list and then only shows a heading "found video fles" but list is not showing after it flashed.

.Zip Only on Firefox...

This extension does not add a toolbar button to your browser. useless. impossible to initiate. tutorial on youtube is ultralowres and no sound - what a joke!

Extremely bad addon. doesnt work

Used to work well but now it seems to do nothing. Sad :-(

The images is downloaded to a mystery folder, I cannot find where it is.

Not working no matter what I do
