Extremely useful supplement to Signature Switch. However, I can't stop T-Bird adding the signature by default to new messages, even if I add the specified line to prefs.js.

since version 5 it seems to ignore the setting in prefs.js!
just create a normal signature in the signature field and afterwards check the "signature from file" checkbox. so no signature gets included by default but if you use add-signature it will work.
