Indeed. To at least cleanup Qwant's homepage from its nursery marketing design add the following CSS :

@-moz-document url("https://www.qwant.com/") {
/* QWANT - HOMEPAGE */
.Home-module__container___1PZLn {display:none !important;}
.Footer-module__container___vsDRR {top: calc(100vh - 180px) !important;}
}

I don't usually propose a CSS here but in desesperate situations it might be an incentive to use an extension which natively relies ona site which has obviously been designed by cartooners.
