I just saw this today, didn't see a thread on it here so here are the features according to mozilla.org: * Improved pop-up blocker: new pop-up blocker blocks even more pop-ups while making it easy to view pop-ups when necessary. * Security improvements: the new release provides additional protection to users against spoofing attacks, the practice of tricking users into believing they are on a trusted site when they are not. When a user visits a secure site, Firefox now highlights the web site address and clearly displays the name of the web site. Firefox also includes a number of other security improvements and fixes, several of which were identified as part of the Mozilla Foundation's new Security Bug Bounty Program. * Live Bookmarks, which help users discover a new dimension to the web by allowing them to create bookmarks that display dynamically updated content such as news headlines. Live Bookmarks let users view RSS feeds, a technology that web content providers use to easily create and disseminate news headlines and summaries. RSS feeds are offered by thousands of sites, including Yahoo News, BBC.co.uk, CNET News.com and most weblogs. * Plugin finder service: Firefox now includes a plugin finder service that makes it a breeze to install plugins, starting with the Macromedia Flash Player for Windows. Additional plugins will be added in the coming weeks. * Improved searching within web pages: Firefox now highlights search terms when the user is looking for keywords within a page. http://spreadfirefox.com/ I've had it for 10 minutes and I've dropped Safari in favour of this. My Safari has been having major issues so I just dropped it, exported my bookmarks and I'm loving Firefox!
