Sorry to hear that. https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration Try updating and reinstalling you WebGL as most times they are corrupted when I see them. Since you chose not to share information when you made your question I can not see what would have helped you.

So good luck with reinstalling them.

Thanks philipp.

This image shows what the model should look like and what it looks like in FF62.0.

The same problem. Grey-white areas appeared on canvas. Any other browser work correctly.

My 3D models on Sketchfab and Artstation are scrambled in Firefox 62.0 They looked fine in the previous version of Firefox and in Chrome.

Fixed in FireFox 62.0.2
