The Firefox only (Windows/Mac/Linux) extension supports up to four unique signatures for each address you’ve designated. Signatures are automatically inserted in both new messages and in replies and forwards.

According to the Blank Canvas website, here are some of the features:

•    Works for Compose Mail, Reply, and Forward

•    Support for single or multiple email addresses

•    Create a different signature for each email address you use in your Gmail account

•    Supports up to four signatures per address

•    Real-time signature preview while editing signature HTML

•    Signature automatically inserted into message above (or optionally below) quoted text

•    Support for special characters

•    Easy setup and configuration interface

Do you use the Gmail Signatures extension?  If so, we’d love to hear your feedback!
