I created `Cloud Firewall` addon. Block connections to big 5 tech clouds based on IP address ranges they own. If a site/page/resource IP matches a bundled list of IP address ranges, it's blocked
It's not a hosts/filterlist type "ad tracker blocker".
It's "firewall" - looks at IP address of URL bar and 1p/3p resources.
