I really like this extension, it's useful to make downloading images just a single button, and it even lets me configure naming convention and download location. There are a few things that don't work exactly right, but I'm still thankful that this extension exists and that it is free.

for some reason its not downloading from sankakucomplex anymore

It doesn't seem to work for rule34.xxx anymore. When saving an image the name comes up with underscores "_, _ _" and videos don't download
