I hope you are going to update this for the new TB. I have missed the ease of filing emails in their folders.

Questa recensione riguarda una versione precedente (0.2.23) del componente aggiuntivo. 

Development version works ok with TB 3.1 It has been submitted as version 0.2.24 and is now waiting for approval on addons.mozilla.org.
