After some delays, Mozilla has released Firefox 3.6.4 (download), the newest version of the popular web browser. It comes with one big addition: protection against crashing due to third-party plugins, most notably Adobe Flash. Crash protection utilizes out-of-process plugins technology to run third-party plugins (specifically Flash, Quicktime, and Silverlight) in a separate process. In the past, a plugin crash would take down your entire Firefox browser. With crash protection however, “the browser will stay running while the portions of websites controlled by the plugin will be disabled.” It only takes a refresh to restart the plugin.
