Now, Mozilla sets out to alleviate this issue with a new Firefox plugin called Account Manager. It currently doesn't do much; it recognizes that you've signed into a website and displays an icon that says that yes, you're indeed signed up under that username. However, Mozilla has ambitious plans for online identity management from within a browser. From its blog post:
"Your Web browser, as your most trusted relationship in your life online, has nearly perfect knowledge of everything you do on the Web. We envision a world where your browser will play an even more active and critical role in helping you control and shape your online experience. To realize this vision, we need to increase the browser’s understanding of your online identity and provide a platform for building new capabilities that securely take advantage of this rich, dynamic set of data that represents the digital 'you.'"
