Does icecat use a custom user config that provides more privacy/security? I see on their page they package it with some preinstalled extensions (JShelter being of interest but only helping to increase the fingerprintability of your browser). All I know about it is that it is a GNU drop-in Firefox replacement (since it is a fork), but it most likely doesn’t enable privacy.resistFingerprinting or many of the other things available in the Firefox config. You will not have anonymity on your proposed setup, nor even using something like the arkenfox user.js which provides much better privacy and security than the loose defaults of Firefox. I would instead recommend Librewolf, or even better Mullvad browser.
Understandable, but you’ll stick out like a sore thumb. Why not randomize in a way that makes you blend in. Like for example, enable “privacy.resistFingerprinting” and randomize other metrics not protected already. With something like viewport, I kinda understand randomizing (from a bank of known common viewport sizes for a given platform)
