New Firefox 3.0 alpha blocks malware, secures plug-in updates

Among the security provisions debuting in the new alpha of "Gran Paradiso," the code name for Firefox 3.0, are built-in anti-malware warnings and protection against rogue extension updates, according to documentation Mozilla posted to its Web site.

The malware blocker, which was first mocked up in June, will block Web sites thought to contain malicious downloads. The feature, a companion to the phishing site alert system in the current Firefox 2.0, will use information provided by Google Inc. to flag potentially-dangerous sites, warn anyone trying to reach those URLs with Firefox and automatically block access to the site.
