Mullvad browser fights fingerprinting. You can check how exposed you are here (no idea how good this site is https://coveryourtracks.eff.org/)
No anti-fingerprinting method currently in use can evade creepjs to my knowledge. And that EFF site has its own issues... it only tests uniqueness across other visitors the site has seen before, and not all possible combinations of data points.
Any Firefox-based browser can be made to do this (I use Zen). This might not be totally bulletproof in this day and age.
we know reddit does aggressive fingerprinting besides using it to identify ban evaders, and im pretty sure they hand that data off to google and openai as well.
The chameleon browser extension attempts to randomize your fingerprint but it seems to be frowned on by privacy advocates due to being able to read pages visited.
Extensions themselves are also frowned upon by privacy advocates because anything that modifies or restricts the DOM/javascript/etc. can itself be detected and used as yet another data point to identify someone.
More reason why script blocking and ad blocking should be native in Firefox (or whoever is gonna succeed them) with at least the same depth as uBO.
Heck, just adopt and incorporate uBO into the engine.
