DDG + Firefox ESR has been my combo. I find DDG does a poor job with local community or very recent results. I often need to switch to google for that. So I’m curious what people have to say. Before the war, I would have suggested Yandex but now I’m not so sure.

Firefox ESR is very customisable with the extensions. But I’m not aware of a solution to have interactive wallpapers. (You could probably make one if you’re a tinkerer.)
