No mention if it works with DoT. Would much prefer Firefox keeping first party support for DoT as much as DoH. Ad/malware blocking becomes a nightmare with DoH.

Maybe try looking it up.

Electric resistance heating is 100% energy efficient in the sense that all the incoming electric energy is converted to heat

Baseboard heating is 100% efficient but heat pumps can be up to 400% efficient. Depending on model and outside temperature. This is because hear pump is not generating heat its just moving it from one place to another. In AC mode from inside to outside of house and in heating mode from outside to inside.

I would recommend Adguard instead of pihole. It’s a lot lighter, and being written in go its very efficient.
