Hey. A while ago I had a Danbooru addon for FF that placed a little "download" button near the bottom of my browser. If the current tab was a Danbooru or booru clone image page, clicking that button would download the image and auto-sort it into folders based on tag, artist, etc. It was definitely working with Firefox 4.0; the original developers might have left, but every time I updated Firefox I also got an update for that addon, so I'm guessing someone has been taking care of it.
The only problem now is that I can't find it! I started a new FF profile because my old one had accumulated a lot of junk (and possibly malware), but I have no idea what that addon was called or where to find it.
The closest thing I found was this: https://addons.mozilla.org/en-US/firefox/addon/danbooru/
...Which might be the right one, except that it's clearly not the current version since I know the one I was using worked with much higher versions of FF than 2.0. Is anyone familiar with the addon I'm talking about? It seems likely that someone else started working on it after the original dev left but I haven't found it. I know this is more of a Firefox problem than a Danbooru one but I figured if anyone would know it'd be everyone here.
