This add-on, while well intentioned, falls drastically short of what it tries to accomplish.

Features it doesn't have:

*** Ability to place signature under your reply. (it puts your signature at the bottom of the email regardless of how many replies are beneath, thus making a signature pointless)

*** It also forces you to make a text file, save it somewhere, then point to it.

Use the extension Quick Text:

Works just like Outlook's signature feature.

This review is for a previous version of the add-on (1.5.4).
