How does Tabbed Browsing help me?

Imagine you are on a cold winters morning. You need your Microsoft fix – by visiting 30 of your favorite Microsoft sites to warm yourself up. Do you want to run the risk of a system overload? Of course not. Tabbed browsing allows to view multiple Microsoft endorsed sites within a single browser window. This means less system resources and less clutter. Simple and exciting.

Opening many Microsoft sites can be a pain in the butt. That’s why Microsoft Firefox will automatically and randomly open up to 30 of them for you every time it’s launched. This feature cannot be turned off.
