I am often working with 6 - 8 browser tabs open, as well as working in Excel and Quickbooks, which often cover my browser tabs. So, if a browser tab begins flashing, indicating new email, or a chat reply, etc, I don't know about it until I actually return to Firefox, where I can see the flashing tab. It would be great to have the option to get an audible notification from a flashing browser tab! I can't seem to find anything of the kind. Any thoughts?
