What you�ll see on the New Tab page of Firefox 13 are your most-visited sites displayed with large thumbnails, reducing the time it takes to type or navigate to these pages. This data comes directly from your browsing history: it�s the same information that helps Firefox�s Awesome Bar give suggestions when you type. Or, if you want to go somewhere new, the URL bar is still targeted when you type on a New Tab page. If you want to hide your top sites � permanently or temporarily � a grid icon in the top right wipes the new tab screen to blank.
