Doing it on restart makes the mitigation de facto useless. How often do you have 10, 20, 30d (or even longer) desktop uptime these days? And no one is regularly restarting their core applications when their desktop is still up.
Enjoy the fingerprinting.
I restart my browser basically every day.
yeah I close out everything as a mental block against anything I'm working on.
I think there's a subset of people that offload memory to their browsers and that's kinda scary given how these fingerprint things work.
Umm, I restart my PC about once a week for security and driver updates.
If you don't, you have a lot more to worry about beyond fingerprinting...
Oh and I'm on LINUX (CachyOS) mind you.
