I can't reproduce that problem locally. Could you check the Web Developer Console for errors please? (In Firefox's menu choose "More Tools", "Web Developer Tools").

Ok i just did some more tests and i can provide more details on how it happens. Here is an updated how to to perform this bug:

1. Compose a new mail
2. Erase any signature that might have been automatically inserted
3. Save it as a draft
4. Open it again, using the "Edit" button on the mail preview
5. Write at least one line of text and leave an empty line below that
6. Place the carret on that empty line
7. Click the Signature button to insert a signature on that line
8. The signature isn't placed

The Webdev console does show some things that could fit, but it's all in french sorry:

Sorry, I still cannot reproduce that. I made a screen recording of my attempt. Did I follow your steps correctly?

Screenrecording-insert-signature.webm

(The signature is also correctly inserted if I compose HTML emails.)

Thanks for trying to get through this with me @pabzm So first off, when i create the new draft, i don't write anything in the mail Subject, neither into the Body. I just delete the signature. Then, when i save that draft and get back to modify it, below the line into which i wrote text (where you wrote "test") i only create 1 new line, not more. Finally, if this has any importance, the signature contains a picture. It looks like this:

Still can't reproduce. Is there another difference in the workflow?

If not, I'm afraid your setup is to blame :/

The messages from the browser console seem unrelated to your problem.

Did you try to change you signature?
