Mozilla adds “out of process plug-ins” feature to Firefox 3.6.4, which shipped June 22. The feature is designed to keep the browser up and running when a plug-in crashes. Users playing the popular Web-based Farmville game complained that their browser was shutting down the Facebook game. Mozilla bumped up the wait-to-terminate period to 45 seconds in the latest release of Firefox. Users can update to the new edition by downloading “Check for Updates” from the Help menu.”]
