Axios I always appreciated Brave's warnings.
Axios Firefox if you put it in strict blocking mode
It will file its cookies in containers for each website and not allow any interaction cross site Coool.
You go one better than this in Firefox: enable first-party isolation (FPI) in about:config.
FF says: "In short, First-Party Isolation (FPI) restricts access to cookies, the cache, and similar data to domain level only. This means that when you enable FPI, advertising agencies canāt use cookies to track your Internet activity as you browse the Web. Usually, marketing companies drop cookies via ads on a website which enables them to track your activities across all platforms that run their ads. First-Party Isolation disrupts this practice by preventing anything but the site that originally dropped the cookie from accessing that data. Once you enable FPI, ad trackers canāt trace your web activity or see all the cookies dropped to your system. This prevents marketing companies from building profiles based on what you do on the Web"
I you enable this setting (I have) it overrides all settings including strict and will tell you so in settings. Is it effective? Who know? Would like to think soš
