I use Thunderbird for sending e-mails, but its signatures are inconsistent. If you send a new e-mail it will add two hyphens above your signature, but when you send a reply it doesn't. I'd like to set it so it does the same for both, preferably so that it doesn't add them for either. Is this possible?


It Thunderbird go to Tools >> Options >> Advanced >> Config Editor

Then search for mail.identity.default.suppress_signature_separator and set it to TRUE by double-clicking it.

Now, you will no longer get the -- before the signature.

  • Fantastic, thank you. That did the trick. Now I can add my own separator instead of having to put up with Thunderbird's. – Styphon Sep 3 '13 at 14:26
