Excellent ! Rated 5 out of 5 stars

EDIT : After reporting a little bug, a few hours after, the bug is fixed. This is really impressive, great developer inside :)
Probably the best screenshot extension in firefox !

OLD TEXT : it seems it's not working anymore in Firefox 17.0.1 on OSX Snow Leopard : the download file is blocking : if you cancel and restart the download, it works...

This review is for a previous version of the add-on (1.3.0). 

Sorry about that, it was something that totally slipped my mind, it's fixed now. Thank you for reporting the issue. :)
