I've been tempted to write something that goes a bit further. I'd like traffic to each site to be routed through proxies with different IP addresses. (Perhaps even to the point where my devices are automatically managing a set of nodes or Lambdas on AWS.)

Along with that, it will still be necessary to fix some browser information leaks that could be used for fingerprinting

If someone is tempted to beat me to it, go for it!

Thats going to break so many websites for you ... Pretty much any service that uses server side sessions across domains. Downloads are often whitelisted to a session, which get invalidated on ip changes.

For exactly those sorts of reasons, I don't expect to apply such a system universally any time soon. In practice I suspect it will only make sense to employ it with a modest number of problematic domains. Currently I use uBlock with javascript defaulting to disabled, manage cookies and local storage, disable referrer headers, etc., but there are still some huge privacy leaks.

On the other hand, it might be possible to devise a solution that works generally but employs white lists or other exceptions for sites that need certain IP-address behavior. That would take a fair amount of effort, but the approach has worked well in similar contexts, such as ad blockers.
