I haven’t followed this but it sounds like the internet is about to become unbearable from chrome. Does this affect firefox? If so, what alternatives are there? (I know of brave but heard it’s not so good). Perhaps safari? But it feels quite different to chrome and Firefox and will take some getting used to.
