Every time I link someone Ecosia, they always complain that it doesn't have a "clean start page", and I do agree. That, and not having the ability to see less or more of certain pages is why no one I know uses Ecosia.
I don’t use Ecosia, because their marketing messages always have been somewhat deceitful. They claimed "plant tree with your searches", but in reality, if you didn’t click on ads, nothing gets planted.
