PC Mag reports the Firefox 2.0 beta candidate has been released.
Reports from early testers compliment two of the significant new features: an integrated spell checker, and an anti-phishing tool. The spell-checker promises to make blog and forum postings more lucid. The phishing filter (an integrated component of IE 7.0 as well) works with locally stored lists of bad sites, along with Google's site listing, and possibly others down the road.
The rest of the interface stays mostly the same, unlike the more radical changes in IE 7.0. Firefox 2.0 does include a horizontal scrolling capability for tabs, and an ability to close a tab directly from within the tab itself. The Options dialog has been reworked to include a horizontal, tabbed based interface, and numerous changes have been made under the hood.
