Compare to cookies. I use two extensions. The first accepts all cookies to bypass cookie banners. The second deletes all non white listed cookies on closing the page. This works well for me since I seldom have more than 20 pages open, and I constantly close them.
Is there a way to avoid browser fingerprinting like this at all (with potential qol benefits) or am I extra screwed because I do things like this in addition to running Linux on a computer I built?
I use LibreWolf which implements pretty tough fingerprint mitigation... but I end up disabling a lot of it because it breaks a lot of sites.
