My Gmail Notifier on a Windows 7 machine is showing "No Unread Mail." As a matter of fact, though, I have many new unread messages in my inbox.
Opening up my Inbox in Mozilla Thunderbird or Gmail's website works normally, and shows new mail.
What can I do to fix the Notifier?

Assuming you're speaking of the actual Google Notifier application (there's a 3rd party app called "Gmail Notifier") then it's probably because Google dropped support for the Google Notifier at the end of January (2014).
Basically, they suggest you use the Chrome browser instead.
