URL: https://austin-eng.com/webgpu-samples/samples/rotatingCube

Browser / Version: Firefox 93.0
Operating System: Windows 10
Tested Another Browser: Yes Chrome

Problem type: Something else
Description: WebGPU / WGSL Not Functional in FF Nightly
Steps to Reproduce:
WebGPU using WGSL shaders is broken in Firefox Nightly and it has been for awhile. Using the absolute latest update with the latest stable graphics drivers installed, reputable WebGPU examples fail to initialize.

For Austin's samples, the most common error is usually:
TypeError: can't access property "getPreferredFormat"

I've seen errors related to the swap chain as well with some other examples, like from webkit. Chrome Canary doesn't always handle every sample, but it seems to chooch just fine on Austin's. Chrome also works with GLSL loading from cx20's demos, but Firefox doesn't. See https://cx20.github.io/webgpu-test/examples/webgpu/cube/index.html
