Hi malwere fighters and browser testers,
The Mozilla Foundation has made some 900 improvements in the Firefox 3 second beta version of this browser. Moreover these are adaptations deal with the user interface, memory use, and other matters to enhance stability, and performance. A lot of these improvements come from feedback by the Firefox community.
Where security is concerned the browser is better hardened against cross-site JSON data-leaks, and the Effective top-level domain (eTLD) service sees to it that cookies and other content from a certain domain is available for that domain only.
Despite of all improvements this is a beta test version, and users are warned that the browser is only meant for developers and testers.
