This update has improved numerous features and now Firefox looks more polished even with the default theme. It looks that the new theme has been designed keeping the upcoming Vista in mind.
Among the new features, in-built Phising Protection will be more useful to the users. It will warn an unsuspecting user to not to fall in trap of the Phisers.
Among the other improvements, now Firefox can restore the session after a Crash. Though in earlier versions it was possible using some extensions. But as the feature now comes integrated with Firefox, several complaints regarding memory leak by the extensions is better addressed.
