Mozilla has released a new beta version of Firefox Lorentz which will isolate the plugin crashes from interruptting or affecting your browser.
So, If a plugin that you have in firefox 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.
Lorentz will be included in future 3.6.x releases Giving you a better uninterrupted web browsing experience!
If you’ve used google chrome before you would be familiar with this thing.
