How to enable a separate process per tab in Firefox

I always keep a watch on Firefox's latest nightly builds as all the cool new features land there first. Here is an amazing news I read about Firefox. The current nightly version of Firefox comes with a secret hidden feature which allows you to enable a separate process for each tab in Firefox! What does this mean for us average users? Well, the process-per-tab model is a very clever architectural solution to prevent crashes. It allows preventing the entire browser from crashing if something goes wrong. With multi-process tabs, only the problematic tab will crash, and try to recover, while the rest of the tabs continue to work properly. If you are familiar with Google Chrome or Internet Explorer, you might be knowing that both use a similar process-per-tab architecture. Let's look now at how to enable this separate process per tab functionality in Firefox.
