Sort downloads by domain name automatically, in Firefox?

"Several months later, I found an even better solution.

Install the Shelve firefox addon
Add a new shelf (tools -> addons -> Shelve -> options -> new). Edit the shelf, and set the ""Filename Template"" to the folder you want to save your images to, appended with %{hostbasename}\%{filename}. For instance, mine is
C:\Users\BlueRaja\Downloads\Images\%{hostbasename}\%{filename}
In the auto-save tab, under ""Save a document to this shelf if the URL matches this RegExp"", set it to .*(jpg|jpeg|png|gif|bmp|tif|tiff|exif)
Any time you want to save an image, just right-click it and choose ""Shelve image"" (and for links: ""Shelve link""). It will automatically get saved and sorted by domain name, without so much as an annoying confirmation dialog!"

I've always used Download Sort.
