So a bit ago I got an add for “canned rambutan”. I had looked up Rambutan a few days prior after hearing it mentioned 10 hours into the video game Baby Steps. I wasn’t using a VPN at the time and I didn’t have fingerprinting protections active but I only mentioned it to a few sources (according to my browser history) all of which generally are implied to be private.
Which of these do you think is the reason the ad networks know?
- Wikipedia
- Startpage Search
- Duckduckgo Search
- My ISP
- Firefox
- My Firefox Extensions
- Kubuntu
- CachyOS
- The omnipotent algorithm connecting my mentions of Baby Steps with my progress through the game.
- Does this only make sense if my browser history is incomplete?
- Maybe I was using DNS over HTTPS via Cloudflare at the time of my search.
Any guesses as to where the weak link is?


I’ve never used AdGuard but you can customize uBlock Origin to fit your needs and block specific things for specific websites. uBlock Origin is commonly used as a default in hardened browsers which would help you fit in with the crowd even more (although I realize you said you weren’t going for anti-fingerprinting, just something to consider)
I’m not really interested in maximum privacy, at least right now. I’m slowly moving there though.
