CloseReview for PackageMapping.com Extension by M. W. M. Swanton
Rated 5 out of 5 stars
It would be great if this was made in a version for 3.1.2. It's listed as compatible, but when I attempted to install it Thunderbird said otherwise. I'm sure anyone using Mac OS X would appreciate it greatly. Haven't used it yet, but I'll give it 5 stars for now.
