Right now, I still use DownThemAll with WaterFox 56, I know that DTA is dead it's impossible to make a new one with all the option in DTA, Download star work, so maybe I can let dta rest in peace.

but I gave only 3 stars because, maybe I'm doing this wrong but I can't use the "fast filter" option, it let me use a single extension, so if a want to download all the gif and png from a page, but not the jpg, jpeg, or bmp and download the webm but not the mp4, I can't use the build-in filter but I have to make a different download for every extension that I want.

How can I use multiple extension in the Fast Filter?

it's possible to make a batch download?

if I can't figure out how to use the fast filter with multiple extension, I think I will keep using DTA. but, isn't a bad add-on.
