Firefox 3.5 RC2: A Quick First Look
Mozilla today released Firefox 3.5 Release Candidate 2, which you can download from Mozilla's Web site. Release Candidate 2 is the first version of Firefox 3.5 that average users might want to run, since it's faster and more stable than the beta versions were. Firefox 3.5 boasts a number of significant changes--ranging from new ways to work with the browser features to under-the-hood improvements that Mozilla developers say will make the browser more than twice as fast as Firefox 3. Here are some of the new features you'll find in Firefox 3.5.
Private Browsing
Like a number of new browsers, Firefox 3.5 adds a private browsing mode to its arsenal of features. While in private browsing mode, Firefox won't remember anything--history, cookies, usernames, or passwords--from your session. When you start private browsing, Firefox closes all of the pages that you currently have open, but it saves all of your open windows so you can quickly get back to what you were doing before switching to private browsing, which is a nice touch.
