"A few lines of code hidden away on a webpage can turn your blocked ads into a unique ID... ...The average ad blocker leaves tiny traces of data on the websites you visit. When those traces are collected en masse, a bad actor (or tech company) could use these signals to identify your specific browser—a process literally called “fingerprinting” in the ad-targeting industry..." https://gizmodo.com/how-your-ad-blocker-can-track-you-across-the-web-1847459354
I saw one video which suggested similar, i.e., use vanilla browsers, and more than one for different sites. In my case, I decided to just use Firefox with some about:config tweaks, the usual addons, but also multi-account containers.
Well, it's no surprise to me, there all kinds of tracking techniques, but I can live with being tracked, as long as I don't have to see those annoying ads that make websites run slow as hell.
