I wrote a blog about Effective Web Tracking Methods that are still widely used in 2026.
I recommended Hardened Firefox.
What do you mean by “Firefox lets you get tracked on the server side”? Use that Doh function with any DNS I recommend, like NextDNS, ControlD, or AdGuard, to prevent tracking via the server side. Also, you can use a VPN to hide your IP.
You use container tabs and private tabs, so how are Facebook and Google going to collect your data? A Firefox container means the entire Google login is limited inside that container only; it has no access to outside what happens. At the same time, you have to use a UBlock Origin or any other content blocker to block other types of tracking scripts outside that container.
About fingerprinting. You can tweak the config to make your Firefox more resistant to browser fingerprinting or consider using user scripts like Arkenfox, Better Fox, or Phoenix. There are also preconfigured browsers like LibreWolf and Mullvad Browser available if you are okay with constant breaking of functionality on websites. If none of this is enough, there is tor browser.







Use Librewolf + uBlock Origin (already pre-installed) + NextDNS via in-built DOH settings.
A well-trusted VPN service like Mullvad, Proton (which has unlimited free bandwidth with free servers), IVPN or Windscribe is also recommended.
Additionally, add these recommended filter lists to uBlock Origin.
