I have saved an HTML signature to file (as per Mozilla instruction). When I write new mail the signature is present but it is preceded by 2 dashes. I have no idea why and would like to have them removed please.

You are refering to the signature delimiter.

what does the delimiter do? http://www.ehow.com/info_12071771_email-signature-delimiter.html

If the signature is placed directly after the reply and on top of the quote, it lacks the "-- " signature separator. That separator is used by Thunderbird to strip off the old signature when replying or changing identities. The signature becomes part of the message and can no longer be automatically removed (since it can't be identified using the seperator), causing a stacked signature


To switch it off for all identities of your accounts: Tools > Options > Advanced> General tab or menu icon > Options > Options > Advanced> General tab

  • click on 'Config editor' button

it will tell you to be careful :)

  • in top search type: separator
  • look for this line: mail.identity.default.suppress_signature_separator; false
  • Double click to toggle 'false' to 'true' or right click on line and select 'Toggle'
  • Close config editor - top right X
  • click on OK to save changes in Options.
