Mozilla has announced a new way to personalise its Firefox browser with the launch of Personas, free, easy-to-install "skins" for Firefox that the organisation says makes changing the look of the browser "as easy as changing your shirt".

Like Google's iGoogle themes, there are hundreds of artist-created designs from sports, fashion and music categories, along with styles from brands and gifted designers.

For those creative types, you can also "turn Firefox into a canvas" and create your own design to share with a worldwide audience of millions.
