Looks like Mozilla is getting all its security ducks in a row before Microsoft begins rolling out a supposedly more secure version of Internet Explorer. On Thursday, Mozilla rolled out Firefox 1.0.1. The update includes several security-related fixes, including temporary fix for the IDN (International Domain Name) bug that was first flagged earlier this month. Microsoft, for its part, has said it will release this summer a first beta of a more secure version of Internet Explorer, release 7.0. Microsoft has declined to say when a final version of IE 7.0 will ship.
