MozMail takes the -- character to mean "signature" and colors it grey. This is a good thing. Unfortunately, for many mailing list digests with many messages in a group, this leads to the whole thing being colored grey when only 1 message has the -- sig starter. I'd suggest the following change: See --, start coloring Continue until end of message, or two consecutive blank lines Or perhaps an option to switch off coloring such as this in the menus would be an easier alternative.

Is this a dup of 54570? If not please see my comment in that bug for more info and a mini test case
