The stable build of Google Chrome has updated, introducing seven security patches to the browser. Version 188.8.131.529 for Windows incorporates four high-priority security fixes and three medium-priority ones.
The medium-priority errors involved local file reference through developer tools, cross-site scripting in chrome://net-internals, and the discovery that some external pages could load with the rights privileges of the New Tab page.
This latest Firefox beta test, introduced Friday, incorporates the long-awaited out-of-process plug-in proofing, code-named "Lorentz." The protection is similar to the tab sandboxing that Google uses in Chrome, but it's focused on preventing plug-ins such as Adobe Flash, Microsoft Silverlight, or Apple QuickTime from taking down the entire browser when they fail. These plug-ins run in a separate memory compartment.
This beta also fixes bugs that had prevented the Lorentz plug-in from working on Macs. Upgrading from Firefox 3.6.3 to Firefox 3.6.4 beta 1 on a Windows 7 computer required a computer reboot for unknown reasons. This seems to be the exception and not the rule, and the majority of users shouldn't experience it.
