The problem is not the missing getPreferredCanvasFormat(), but that a field named navigator.gpu is undefined/not set. That might be because of the disabled webgpu in your settings?
YouTube on Firefox was very crappy on Linux (bazzite). I had to disable hardware acceleration a few years ago to have videos properly render colors. I just remembered recently since I reinstalled my browser and the problem came back. Any chance you might have disabled that at some point as well on your Mac for some reason ?
I don’t think so. I use Firefox Developer Edition as my default browser. It is possible that I disabled those flags at some point but I would think it would reset after a clean install and not being logged in to Sync.
So this is interesting.
I am running this on a Mac (Intel), on clean install of Firefox.
It didn’t work.
If anyone is curious I’ll post what I think might be relevant.
I got this error:
But I looked at the documentation for
getPreferredCanvasFormat()and it exist.mdn_: GPU: getPreferredCanvasFormat() method
So I looked at
about:configand I listed what I think might be relevant:dom.webgpu.enabledfalsewebgl.forbid-hardwarefalsewebgl.disabledfalseThe problem is not the missing
getPreferredCanvasFormat(), but that a field namednavigator.gpuis undefined/not set. That might be because of the disabled webgpu in your settings?Yeah, I figured.
So a clean install of Firefox on an Intel Mac should technically be fine. I guess Mozilla turned it off for abuses like this.
Thank you for your input.

The site says at the top that it uses webgpu to freeze macs. And you have webgpu disabled
