Rated 4 out of 5 stars

Version 6.8 ran for a day or so then quit. Button on Firefox 15.0 is in motion as is normal. Clicking downloader brings up the Download Manager screen. it shows no urls and all folders are zero. It had many urls at first, but I deleated them. Could never get it to work after that. I use Ubuntustudio 12.04 in Gnome or Xfce with same results. When it worked, the downloader worked great.

This review is for a previous version of the add-on (6.8).
