Thunderbird and multiple signatures
November 3, 2007 – 8:33 pmI’ve been using thunderbird for almost 3 years now (I think) and I recommend it to my friends.
It works great, I can setup multiple accounts with their own folders, easy configuration and personalization,.. I just like it.
But one thing that bottered me was the lack of capability for using multiple signatures and not just one per account. So today I add a thought ” Jezzz there has to be a extension for this, this is thunderbird..” and you know what? of course there is 
Its “Signature Switch“, created by Achim.
“Signature Switch” offers removal (and re-insertion) of your signature with just one click of a button and easy access fro the toolbar. Supports HTML signatures and allows some useful configurations.
