Firefox 11 BETA 1 released with Page Inspector 3D View

Just after the release of Firefox 10 stable, Mozilla has pushed another version for public testing, Firefox 11 BETA 1, that comes with exciting developer-oriented features.

The new interesting addition, Page Inspector 3D View, allows one to visualize a site from its components point-of-view, displaying its various pieces just like a building, with 3D components on top of others, probably designed for a better understanding of how web-sites work, what is the relationship between an x element and other y element, what is the percentage of resources used in that particular site, complete web-sites explorations (are there elements outside of this page?) and more.

Page Inspector 3D View has its roots in an add-on, Tilt (the 3D part), furthermore adding extra functionalities.

How do we use Page Inspector 3D View?
The computer must be WebGL-capable (consequently a 3D button will be displayed on the toolbar, located at the bottom of the page).
Open a web-page, right-click inside the page and select Inspect Element, then just press 3D.

When in 3D mode, zoom in/out, press&drag come handy when maneuvering the web-site to conform to our needs.

Mozilla Firefox 11 BETA 1 has already landed in Ubuntu 12.04 LTS and is available via its official BETA PPA (Lucid, Maverick, Natty, Oneiric)
