QUOTE: The revamped Firefox includes a new interface theme and more security protection such as built-in phishing protection. It also has session memory, which, when the browser is re-opened, brings back the set of Web pages that were in use when it was last closed. Changes have also been made in the technology to import RSS feeds, which now offers a feed list view with title and first lines.
