Ip tracking is worthless. Most people have half a dozen devices. I was actually shocked recently that I have 22 devices on my network. Then think about a relatively small business. There could be hundreds of devices. All from the same ip
You can combine IP address with fingerprint built from WebGL video card information, fonts list and rendering details, OS name, CPU type, memory size (yes, browser provides this) and screen resolution.
I'm a bit confused, is the nature of the complaint that Firefox lets you use multi-account containers without at the same time forcing you to use resist-fingerprinting? Because you can certainly choose to use both.
If your point is that resist-fingerprinting would be a sane default, I agree. But Mozilla insists that most firefox users would be too confused by a few websites breaking because of it.
A small network will likely have identical setups. Plus I pointed out directly the one case of ip tracking being useless. Clearly there are other way to track an individual computers. But your counter argument is irrelevant regarding in my limited scope reply
