Review for Recipients Overview by BRW
Rated 5 out of 5 stars
This works exceptionally well. I discovered it by accident when just happening to look at extensions the developer had created for Firefox when I was looking at Locationbar², another nice extension he did for Firefox. I had wanted an extension, such as, Recipients Overview, but had not realized something like this was available for Thunderbird. Thanks!!!
