Mozilla is rolling out an update of its Firefox Web browser that adds support for plugin isolation. Version 3.6.4, which includes the new feature, was officially released on Tuesday and will be deployed soon through the browser's automated update system.
It is unusual for Mozilla to deploy a major new feature in a minor point update, but the plugin isolation capability is a worthy exception to the rule, since it will significantly improve the browser's stability. In the new version of Firefox, plugin components like Flash and Silverlight will run in external processes. When these plugins crash, the browser itself will not be terminated.
