Working OK in 64.0.2, being a nice visual aid for those playing with Cloudflare's DoH or DoT and ESNI DNS.

Given the now obsolete core mission of this extension, one must train to recognize the opposite:
Red = all Cloudflare
Orange = some Cloudflare
Green = no Cloudflare
Easier said than done. :)
Grey = "No requests have been processed yet."

Nice.

I'll probably not use it, but it's a respectable alternative to 'Block Cloudflare MiTM Attack' – https://www.reddit.com/comments/8ixnfa/-/e1jgl9s/
