Mozilla released FireFox 2.0 today and it is available for download from their website. I haven't used Firefox much to know what has changed from 1.5 but they do talk about improved tabbed browsing, session restore, RSS and Live Titles as some of the key things in 2.0. It also has a spell checker built in and provides search suggestions. Also built in is phishing protection which warns the user about suspected forgery.
IE team sent mozilla a cake to congratulate them on shipping Firefox 2. Hope they enjoyed it! It has been a good couple of days for the browsing world.
