If you have canvas randomisation turned on (firefox) you'll always be unique but also not traceable between sessions.

How do you turn on canvas randomisation in Firefox? I can't seem to find anything about it.

I found this in about:config, defaults to true apparently: privacy.resistFingerprinting.randomDataOnCanvasExtract

But you have to enable privacy.resistFingerprinting for it to work first. I enabled that and now the EFF test says "randomized" for the hashes but also Lemmy went from dark to light theme somehow.

privacy.resistFingerprinting breaks a lot more than just themes. Many of the weird problems reported in Firefox (and forks) are just from enabling it.

It has some pros but also TONNES of cons. Everything from a completely blank page to wrong timestamps to poor textures and so much more. Sometimes you will be flagged as a bot and prompted with literally infinite puzzles, thus effectively banning you from a website.

Some of these problems get fixed but new ones also get born. I personally use it but I also expect breakage and worse performance.

Yup, canvas is heavily weighted in this test based on the results.
