Lovely Addon! Rated 5 out of 5 stars
Wonderful addon! It does It's job as It suggests. I'm using it on a OS X 10.7.4 It froze a couple of times, but now It seems to work. I can suggest the following;
*Being able to pick downloading message thread by their ID's.
*Being able to pick download formats, maybe even customize.
*Make sure the addon doesn't get firefox frozen when downloading(yep It's frozen right now :/)
Any way amazing addon! 5/5
