Signature size
I created a signature years ago. With the last Thunderbird update, the signature font (and image) shrunk in size. I would like the signature to match the font size of the message text, like it used to. I can't find any information about that, or any explanation as to why it shrunk.

There it is! That's what I needed to know. For others, the path is Settings > Composition > HTML Style > Size > Medium.
Yes, and read the instructions carefully. This should remain MEDIUM to prevent your recipients from receiving unwanted font sizes.
