Facebook photo albums

I want to download all the photos in an album in a single post. This could be from 5 to 50 or more photos. I have tried extensions. Photo Live didn't work at all. Download FB Album mod only downloaded the visible pics and pics in comments. i.e. if there is a post 30 photos and 5 visible in the post it only saved the 5 + 3 pics in comments. Is the on that works? Prefer it in Safari but can be chrome or firefox. ty
