Firefox Lorentz Beta beginning to handle plug-in Crashes
I heard long time ago that Mozilla had planned to separate the tabs into different processes in Firefox 3.6 release similar to Google Chrome. Because of the time constraints, Mozilla plans to release this feature as well as other features in future release of Firefox as updates. I think Firefox Lorentz is the first feature that Mozilla plans to release. On its homepage, it states that
Firefox “Lorentz” provides uninterrupted browsing for Windows and Linux users when there is a crash in the Adobe Flash, Apple Quicktime or Microsoft Silverlight plugins.
If a plugin crashes or freezes, it will not affect the rest of Firefox. You will be able to reload the page to restart the plugin and try again.
Firefox Lorentz will become part of a future release of Firefox 3.6.
Firefox Lorentz only improves plug-ins handling. According to Firefox roadmap, the process separation for tabs will be made into Firefox 4.
