Ideally, going by the cancerous nature of the internet in 2021, web browsers should ship with ublock origin, automatic https upgrades, an usable js-blocking toggle and LocalCDN-esque features out of the box. Chrome would never do something like that but maybe firefox could. Improves privacy and usability overall.
I am sure this isn't the first time the idea has popped up.
Should LocalCDN be a built-in feature in Browser?
