Firefox now includes new developer tools, Page Inspector 3D View. Nicknamed Tilt, a tool that highlights the structure of a page better than a flat view, so anyone can immediately understand the relationship of the code to the page output.

After selecting “3D†View in Page Inspector, just hover your mouse over the elements to get more information about each piece you select.
Another feature is the new Style Editor tool, which allows developers to edit CSS stylesheets like a text editor and see changes instantly. Firefox also introduces Add-on Sync. to let users sync add-ons between computers.
