I currently use Firefox and DuckDuckGo, but I’m thinking about getting a new browser and search engine. Are there any good recommendations. Privacy-focused is non-negotiable, and i would like it to be open source.
I have heard of Ecosia. How exactly do they work? If they truly do help the environment, like they claim, I may look into that. Is there any evidence? Looking into their privacy policy, it doesn’t seem too optimal.


Ecosia is both, and OP’s question is for both. Please pardon my perfect answer.
Excuse me, I didn’t realise OP was also asking for search engines. (Not sarcasm)
