Hmm no

Our mission is to ensure the Internet is a global public resource, open and accessible to all. An Internet that truly puts people first, where individuals can shape their own experience and are empowered, safe and independent.

Thats the first paragraph from their mission statement here https://www.mozilla.org/en-US/mission/

Doesn't say anything about environmentally friendly. Also I think this part "where individuals can shape their own experience and are empowered, safe and independent.", and their stance on AI in their browser and it being opt in make sense. Some people want to use it. Let them have a safe and private way to use it. Maybe Mozilla can show how a privacy respecting AI experience can be. Wouldn't that still be a net good?
