SketchUp Free failure to launch

I wanted to see how SketchUp Free works, so I want to app.sketchup.com and clicked on the “Start Modeling” button. All I got was a throbbing SketchUp logo. How long does it take for Free to launch? FWIW, I’m using the latest version of Firefox, which touts its speed.
