Hi,

You seem to be viewing the chat function. I don't know why tabs do not appear and the icon for selecting a different function does not appear. But you should be able to select File - Close and see the e-mail function.

If you always see the chat function when opening Thunderbird, perhaps the first setting in Thunderbird settings - General will help.

Unfortunately, nothing works. When I click on settings or account settings, nothing is displayed. The bar at the bottom shows that the emails have been downloaded.

Did you select File - Close? What happened?

Are you in full-screen mode? What happens if you press <escape> to leave it?

When I click file and close nothing happens.

When I am in full screen mode ESC shrinks the window

Were you in full-screen mode? Did pressing escape and leaving full-screen mode make it possible to view something other than the chat window?

Do you have add-ons installed? Which?

Are you using test release or an esr release?

Can you access the troubleshooting options in the help menu?
