Rated 2 out of 5 stars

The add-on doesn't work with the new version of Thunderbird (3.1.1).

This was a helpful add-on with earlier TB versions. I hope the author will provide an update.

This review is for a previous version of the add-on (0.9). 

Hi,
Forward 0.9 is compatible with Thunderbird 3.1.* and it should be able to install. You do need an active internet connection however, since Thunderbird needs to connect to the addons server to check the compatibility...
