. A preview version of Lorentz, Firefox 3.6.3plugin1, was made available on April 8, 2010. Betas of Firefox 3.6.4 were made available starting on April 20, 2010. Firefox 3.6.4 was released on June 22, 2010. The Windows and Linux versions incorporate out-of-process plug-ins (OOPP), which isolates execution of plug-ins (Adobe Flash, Apple QuickTime and Microsoft Silverlight by default) into a separate process. This significantly reduces the number of Firefox crashes experienced by users who are watching online videos or playing games; the user can simply refresh the page to continue. Mozilla states that 30% of browser crashes are caused by third-party plugins. Support for other plug-ins by default in OOPP and on the Mac OS X platform became available in Firefox 4. Firefox 3.6.6 lengthens the amount of time a plug-in is allowed to be unresponsive to the point before the plug-in quits. Firefox 3.6.7 was a security and stability update that fixed several issues. Firefox 3.6.8 was a security update that was released a mere three days after 3.6.7, to fix another security fault.
