Thunderbird not Collecting Outgoing Email Addresses

more options

I have Thunderbird set to "Collect Outgoing Email Addresses" and add them to my address book. This is not happening, the outgoing email addresses are not being added to any of my address books. Any suggestions? Thanks

That solution seems to have worked. Strange thing is that I have been using Thunderbird for years and there should be dozens of addresses in the "Collected Addresses". But when I looked there were only four. Hopefully this "New Contact/Restart" solution continues to work.
