It’s been a long while since I looked, but I remember it being a thing in tails to specifically not resize your browser window or only have it full screen to match a ton of other fingerprints.
Plus since it was a live distro that reset on every reboot it would only have the same fonts and other data as other people using tails. Honestly, I hate that all that info is even available to browsers and web sites at all.
