Amazingly useful to automatically sort downloads by file type and/or domain, into any sub-folder of your downloads location. Should be built into Firefox.

My guess is that the negative reviews are for folks that don't understand regular expressions (although for most folks, they'll just need a simple keyword).

Unfortunately it doesn't work, please fix it

This allows you to pre-select folders for automatically downloading files of different type/different names. This is exactly what I needed - thank you.

Doesn't work

Very nice. I have a request for you to consider. Usually when I save an image it's because I found it interesting, and usually I want to share the link too. I'm wondering if "download and copy url" could be an option somehow. Also it would be helpful to provide some regex examples, I'm using this for images: .*\.(jpg|jpeg|png|gif|JPG|JPEG|PNG|GIF)
