Look at my INBOX; it shows nothing.

Only you can check your   INBOX.
You will find something in your  INBOX   when somebody sends you a private message   ..........

1. Why are you using Firefox 14.0.1? The current Release version is 49.0.2 .

2. Are you talking about an email INBOX?

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.
