Tabs

Through a system called tabs, Firefox allows you to open multiple webpages all in one window, without the usual clutter of Internet Explorer. The days of frustrating clicking back-and-forth between websites is now over.

Integrated Search Bar

The exclusive integrated search bar enables you to search any of the hundreds of your favorite sites (including Google, dictionary.com, eBay, Amazon, CNN) directly from Firefox. This quick search is always close at hand, located next to the address bar.

Built-in Popup Blocker

Because it's deadly effective, you can rest assured that not a single annoying popup hurls its way towards you. A whitelist is available to unblock sites to allow them to make legitimate use of popups.
