When opening the latest e-mail, ALL trailing mails open at the same time.
When there are mail with 10 trailing mails, when I open latest e-mail, all 10 open at the same time. I only want the latest e-mail to open, but I want to be able to open other trailing mails if necessary.

You posted in the Firefox support fora queue. Firefox doesn't do email, it's strictly a web browser.
If you are using Firefox to access your mail, you are using "web-mail" such as Yahoo!Mail or Gmail. You need to seek support from your service provider or a forum for that service.
If your problem is with Thunderbird, let us know and we can move this thread to the Thunderbird support queue.
