Thanks, unless I'm missing something important (I do from time -to-time), the "import" function for "Mail" is limited to "Communicator x, Outlook, and a few others, a method to import from Thunderbird (itself so to speak) isn't there. Now this hasn't been a problem in the past, as recent as December I put a new Dell PC into service for my wife, and copied her Thunderbird mail files (just a copy) into the Mail folder on the new PC, worked fine. Has worked for me in the past too, but not this time. I've put some considerable effort since posting this thread, and still haven't figured it out (there should not be a need to "import" or otherwise "map" protocols, the protocol/coding is the same one copy of Thunderbird to the next). This time I am working form a backup file, not he old application of TB, I may have done something wrong in the backup step. I also find it strange that the subject isn't addressed on the Mozilla/TB help forum. The subject is addressed, my difficulty isn't.

Maybe, Open TB. In the Account Bar in the left pane right click on the target account, i.e. shaddy@yahoo.xxx. Select Settings. In the right pane of the appearing window is a signature text box. Google produced this expanded information using keywords "thunderbird signature" (sans quotes). Here is a link that might be useful: Mozilla This post was edited by damccoy on Fri, May 31, 13 at 19:33

fruitjarfla, Thanks for the answer but just yesterday I was looking for something in the hidden icons on the toolbar & there was an envelope. I moved it out of hidden & it has worked perfect all last nite & so far today. When Thunderbird did the update apparently somehow it got moved there. I should have thought to look there but didn't. I'll know where to look next time one goes hiding on me. Thanks again, Dar

I think that's one of those programs that people either love or hate. Not much in between. Here's a thread from an email forum on the subject. The site's email guru has a bit about his negative experience with the program (mainly its company's 'shady' practices). Take it FWIW. :-)
