Microsoft has released a major upgrade to Internet Explorer. Within days, Mozilla released version 2 of the popular Firefox web browser. So, what's new?

IE7 adds tabbed browsing, which allows you to open links in a new tab, without leaving the page you are on. This is especially useful when searching or shopping.
Firefox2 has added a close button to each tab, a list of recently closed tabs to the History menu, and the list of tabs now scrolls when there are too many to show.

IE7 now understands RSS, Atom, and other feed sources, to stay up-to-date with news, classified ads, and more.
Firefox2 has integrated Google Suggest into its search box. 

Both browsers now alert you to forged websites.



IE7 has made significant security gains to address persistant problems it has dealt with in previous versions, including the aforementioned phishing filter, safer web address interpretation, better control over ActiveX and add-ons, and pop-up windows now include an accurate address. IE7 also runs in protected mode to ensure it can't do anything bad to your system, however, this feature is only available for Windows Vista.
International web addresses, and some advanced styles now work in IE, and many display problems in IE6 have been fixed.

Firefox2 automatically restores your windows and tabs, history, in-progress downloads, and anything you typed into forms after a crash, upgrade, or whenever you start (if you've asked for it).
