I could see that.

Not the issue in my case though.. I don't use any extensions on my mobile browsers.

Heh, maybe it's the opposite then! Like an accumulation of shitty trackers, because you don't use uBlock or privacy badger or the like. That would be pretty ironic

Trackers do not really accumulate though, no? Or can they install something persistent (web workers maybe?)

Store stuff in IndexedDB?
