want to add a second email address to my Tbird account to appear as a separate screen when I log on david Feb 4, 2023, 9:00:45 PM Would you please expand on what you want? It's not clear to me what you want to do. I have an email address on Thunderbird and the correspondence is shown when logging in. I have registered a 2nd address and want to access it as I do the first ie move from one to the other and not necessarily show both at the same time
