as soon as i open anything in an email in thunderbird i get a new tab and it takes me out of my email account when i delete this opening

Back up there. You have lost me and I would guess everyone else as no one has attempted a raply in this time.

Opening an email in Thunderbird has by default opened a new tab since version 3 was released in 2009. But I have no idea what " I open something in an email " actually means to you. Are you opening emails or links of attachments or what?

I guess I was not very clear and I apologize. I just opened your email reply and read it. As soon as I clicked on view and reply to your email it automatically opened a new tab and when I finished replying to your message and I leave the email it takes me out of my email account and I get my home page in Windows 11. As soon as I delete the new tab then I go back to my email account once again. I don't understand why it has recently started doing this. I hope this explains it better.
