not saved or not remembered. They are actually different things.

This post is for a different problem, but it does explain how to use about profiles to check things out. https://thunderbirdtweaks.blogspot.com/2019/09/i-lost-my-profilemail-on-update-to.html

Thanks so much. When I went to profiles, there were multiple profiles set up. I deleted all of them but one and when I clicked on launch new profile in new browser, I did see all my folders. I therefore set that as the default.

But when I closed Thunderbird and then re-opened it, I first got my folders. Then I re-booted the machine and when I opened Thunderbird, it again acted as if it had not created a profile. When I went into profiles, it now had two - the new one it was trying to create as the default and the correct one. So you are correct the it is saving but not remembering.

Any thoughts? Thanks again.

where is you profile stored? in troubleshooting information on the help menu, click on the show profile button.

I am thinking I really don;t know what is going on. So starting with basics.
