Even simply talking about third party assets included on a site, a service doing something like providing comments can and does do just as much tracking. However, you can't just opportunistically strip it out since it's part of the functionality.

Well, for most sites, I don't give a shit about user comments, so I block them (using uMatrix), including cancers such as Disqus. Just as for most other 3rd party service. On top of that, I contain sites I regularly use or that I login to into different containers inside Firefox.

It's one example. You've also clearly given yourself a very unique fingerprint with extensions and your specific configuration and usage of them. The way you describe how you use the browser doesn't sound like a way that gives you the privacy that you're seeking. It stands out.

My fingerprint probably looks more like "curl trying to imitate current Firefox on Windows" than "the guy who googled 'big tits porn' yesterday". And I make sure that fingerprint ends up at as little different parties as possible.

Third parties receiving the data and providing code aren't limited to the ones with a presence in the web site's client-side code. For example, with the New York Times, you can happily block Google's client-side assets, but how are you going to block the server-side integration?

NYT will end up in a container where all referrers are faked, cookies and DOM storage cleared after I close the tab, 1st party isolation in Firefox is enabled, canvas randomized, etc pp.

So, as I said, you made yourself stand out from the crowd as incredibly odd and unique to the point that you are guaranteed to receive special attention. I'm sure you also see a lot of extra captchas, etc. across the web. You stand out. You're suspicious. It's a unique signature.

I certainly do thing that first party isolation should be the default approach in every browser, but I'm not telling people to enable it on their own as a way to improve their privacy, especially with it hidden away. Look back at my original post on Reddit and the thread here.

Firefox does actually block lots of shit by default in Privacy Mode (so "normal" users using privacy mode will generate noise I can hide in), and Firefox has introduced GUI to enable tracker blocking in recent versions, thus generating even more noise for me to hide in.

That's not noise, and you aren't hiding in it. I don't know what you're talking about. I'll also refer back to my original post and thread again. I already went through enumerating badness, and Firefox is deliberately only doing a very cautious opportunistic form of blocking.

I don't find it an interesting conversation and would rather not continue. You don't seem to understand what I've been saying, and you aren't disagreeing with it, but rather bringing up non-sequitur points / tangents. It's not what I want to talk about.
All I have to say is that the Tor Browser approach is the one everyone else should emulate instead of messing around with privacy theatre and enumerating badness. I never said enumerating badness was useless, just unworkable as a solution. If you disagree, that's your problem.
