How to view 3d model of html page?

Question

css

Hello.
How and where to see the 3d model of the page? There used to be a Tilt extension for Firefox. Now it seems to be gone. It seems that there should be such a tool in the Firefox debugger, but for some reason I can’t find it in my version. Firefox 57.0.1.
