And for me this is one of the reasons - probably the biggest - that I don't want to buy an ipad. Because it doesn't allow to run the full blown firefox
I've spent hours debating moving to ipad instead of android tablet and it ends to 1. lightning instead of usb-c (can't afford the ipad pro) but ok I can live with it and 2. firefox which is just a blocker
> uBlock Origin already performs CNAME decloaking and blocks this approach, it’s pretty cool.
... which in return is a static list of domains which needs to be regularly updated, and therefore is not really failsafe. uBlock0 uses Adguard's scraped dataset [1] as a fallback source to do this, as Chrome Extensions cannot make DNS requests without a DNS-via-HTTPS endpoint.
Firefox, however, has provided the `dns` API [2] to do requests via the native OS resolver (which in return is also not failsafe due to being unencrypted plain-old-manipulateable DNS UDP requests)
And yet facebook is already do something along the same lines by adding fbcid=<trackingnumber> to every outbound link and then the site that receives the link can report back "I saw fbcid=<trackingnumber>". Sure it makes 3rd party tracking require more trust but wouldn't some analysis tell you if your client is trying to game your ads for revenue etc...?
That would be more effort than including a single html-script tag to import google analytics. I have hope that most parties would decide that the extra server load and difficulties would make it not worth it.
You underestimate the desire for precision tracking, unfortunately. Hiding behind custom subdomains is common.
Stepping up to cloaking it to be delivered from the application is more effort but it'll happen.
You overestimate the technical ability of publishers. Frankly, it’s pathetic to rely on a third party’s hot linked JavaScript, but no one can be arsed to understand how it works, so they just add the tags to GTM instead of realizing that they could trivially implement A/B testing or whatever themselves.
