Rated 4 out of 5 stars
first of all, let me tell you that I love this extension. I use it constantly to automatically switch signature flawlessly when I choose to switch a sending account. used to work perfect in the past, and it still does when composing HTML messages (well, it enters an extra carriage return when inserting the new signature, although I can live with that), but it has recently stopped working for plain-text messages: it just adds the account's signature at the bottom of the message, and if I choose to deactivate signature it only removes the last signature inserted. any ideas why this is happening? is it a TB3.1 issue, or could it be a SS1.6.6 problem?This review is for a previous version of the add-on (1.6.6).
