THis is what I was looking for.... great.
But I cannot install version 0.99.6-tb in TB 3.0 b4. (refused by TB)

Which version of TB is compatible???

Questa recensione riguarda una versione precedente (0.99.6) del componente aggiuntivo. 

For TB 3.0 b4 please use the version 0.8.3 (https://addons.mozilla.org/thunderbird/addons/versions/13564#version-0.8.3)

If you use current nightly builds (or the release candidate 1 (see https://wiki.mozilla.org/Releases/Thunderbird_3.0rc1)) you can the current version of this add-on (at the moment 0.99.7)
