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)
