Mozilla has unleashed a new version of Firefox, which is claims is faster than ever thanks to a strategy it's calling 'procrastinate on purpose'.

Unlike human procrastination (displacement activity like washing the dishes instead of completing a tax return), Mozilla's system involves creating a 'to-do' list and performing tasks at the optimal time.

Features that are rarely used have been deprioritized, which means the page can be rendered more quickly.

For example, the browser won't search for alternative style sheets until after the page has loaded, and won't load its auto-fill module until there's actually a form on the screen that will use it.

If your system is running low on memory (below 400MB), Firefox will now suspend any tabs that you haven't used for a while.

Any suspended tabs will reload when clicked.
