I am using Thunderbird 91.6.0 with WIN10 Pro. In the past Thunderbird always opened with a list of my 3 email accounts. I could tap the account of interest and was presented with a list of my folders. I could tap the folder of interest and view the emails - usually I would tap the inbox folder. I have not made any changes to the configuration of Thunderbird. Today I found that I was presented with the inbox of the first email account. The only way I can access the other email accounts is by way to the GO tab at the top of the screen. How can I reconfigure Thunderbird to open with my three email accounts on the first screen?
