These are some of the only ads I see online these days (on Read the Docs, mostly). I don't use ad blockers, but I do use tracker blockers, and those block pretty much all ads, for obvious reasons. Not these ones, though. And that's how it's supposed to go.

Can you elaborate on your setup?

I'm not OP, but I have my browser setup to block trackers only, nothing that's billed as an ad-blocker.

I use Firefox with Strict Enhanced Tracking Protection [0] and Privacy Badger [1] as an extra layer of protection. Some sites, mostly news orgs, complain that I'm blocking ads, but inevitably these are the sites Privacy Badger reports 20+ trackers blocked. I'm happy to see ads online, I'm just not willing to sacrifice my privacy for them.

Will switch to firefox because of this, absolutely disgusting.

Safari, Chrome, and Edge already partitioned the HTTP Cache by site; Firefox was the last major browser not to. It's great that Firefox is doing this, but it's not a differentiator.

The way they phrased it, in the post implies otherwise?

A few days ago there was a paper posted here about favicon cache being used for tracking [1]. I wonder if cache partitioning also prevents that? [1] https://news.ycombinator.com/item?id=25868742

Favicons are mentioned in the article as one of the caches that get partitioned now.

Really? Chrome wants to protect against tracking? Isn’t that their business model?

I wonder how many people reading this comment are thinking, "what's a fax machine?" :o) I like the analogy, but I wonder how effective it is on anyone under the age of what, 35?

My bank still accepts fax documents. All I would have to do is find a fax machine ...

On linux you can use [efax](https://linux.die.net/man/1/efax) and a modem and... ooops, good luck finding a modem.

I did this for real ~10 years ago when a stupid company didn't accept a scanned PDF by email and required a fax of the actual document "because security". The difference is that I had a modem in an old laptop at that time, so I just send them the same scanned PDF.

Now I'm wondering if there is a provision for sending faxes somewhere in the GSM/3G/4G rabbit hole of standards.

Is this really important given that browser fingerprinting can almost always identify a web browser?

Nobody would accept interconnected face scanners in every building they walk into but online it's somehow okay.

You know what is surprising? A lot of people will easily accept those face scanners too :/

A lot of people accept that which is beyond their control. That doesn't mean they are Ok with it, just that they don't know how to do anything about it or often that it's even happening.

Use uBlock Origin, Multi Account Containers, Privacy Badger, Decentraleyes and CookieAutoDelete with Firefox. Make sure you aggressively clear cache, cookies, etc., periodically (with CookieAutoDelete). You’ll probably load the web servers more and also add more traffic on your network, but it will help protect your privacy since most websites don’t care about that. When websites are user hostile, you have to take pr…

You forgot NoScript. uBlock Origin with privacy lists negates the need for Privacy Badger. Decentraleyes is neat but I've found multiple sites it breaks.

Why NoScript? uBlock Origin in medium or hard mode can be used instead.

Wait does that mean hsts cache is per origin?

That seems like it would make tls stripping attacks a lot easier.

These advertising networks are destroying web performance. Most of these "Supercookies" are optimizations to improve performance. By abusing them, advertisers have turned what should be a great performance tool into a liability. I know FF suggests this won't significantly affect most websites performance, but web advertising and trackers are already responsible for a huge chunk of performance issues already. Of cours…

Blocking ads and installing some sort of cookie auto-accepter/deleter[1] is the best and mopst optimization saver which you can have without disabling javascript.
