[Guide] Ripping models from Sketchfab

So far, i was able to get a model, and am now trying to get the textures. I have ninjaripper setup properly. It launches Mozillz, and I go to the with /embed. The model loads while in full screen, I spin it around a bit, and press F9, but it doesn't freeze, and no files appear. What am I missing?

edit - was using wrong mozilla

that was fun - worked out ty!
