When I open a new tab, the new tab used to show shots of 6 or so of the last sites I'd viewed, so I could easily click on one and go to it. Now it shows a blank tab and I have to type the URL of the page I want. How can I change it back?

Did you have the Google Toolbar installed? * http://www.google.com/support/toolbar/bin/answer.py?answer=115561 Web-browsing tools : Google new tab page and most visited websites Other extension that have a similar feature: *Speed Dial: https://addons.mozilla.org/firefox/addon/4810 *Fast Dial: https://addons.mozilla.org/firefox/addon/5721
