I feel like this might be a better and more feasible solution. Is there a reason that JS can collect as much data as it does about our hardware? I feel like I always hear the mantra, "The browser is a sandbox," but reading articles like this make me really unconfident that that is true. I don't really have too much of an idea of how WebGL works, but I wonder if there's a way to create some sort of additional abstraction layer between a website and the hardware? So JS just has access to "hardware interfaces" like a CPU and a GPU but can only interact with via this interface. That way, even if a site wanted to, the best it could do is determine that your computer has a GPU or a CPU but not how many cores or what type of GPU? This would however have the downside of incurring an additional latency with an additional abstraction, but if there was a way you turn this off with trusted websites and only leave it on when you're using a site you don't trust it could be more usable? It just seems better than disabling JS entirely since a lot of websites just completely break without JS. It just seems like with the amount of information that JS can collect, even if you're using TOR or a VPN, if you crunch all the information about a particular user, like the kind of OS they're running, the version of the browser, the screen ratio, mouse click movements, time of access, number of CPU cores, type of GPU, whether or not it's a VM, etc., it just feels like you might be able to devise a pretty reasonable heuristic for where this person is and the kind of computer they're using. I can't really say I know the extent of browser and JS capabilities, but these things already seem alarming enough where I wouldn't really feel super confident that I can't be tracked even with TOR or a VPN. Edit: Just discovered something similar to this is being worked on already! https://gpuweb.github.io/gpuweb/#malicious-use https://gpuweb.github.io/gpuweb/#malicious-use

The user should have full control over everything. For example, if the user want to configure it so that all JavaScript time reporting reports that everything takes zero time, then that is what it should do in that case. If the user wants all timeouts to expire immediately (so that JavaScript-based animations will take zero time), that can also be done, then. You should have enough ropes to hang yourself, and also a few more just in case.
