Lorentz is Firefox version 3.6.3 with a much delight in update. Firefox beta allows you to separate plugins, such as Adobe Flash, so that they don’t crash the entire browser when they encounter issues and the plugin is replaced with a dark image notifying the plugin crash. This feature is called “out-of-process plugins.”
According to Mozilla Firefox Lorentz Web Page:
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 3.6.4 final release is targeted for early May.
