Re: Do NOT install Quant browser extension!
It would be helpful if you provided a link to the add-on that you are talking about. A quick search suggests that there are a large number of Qwant (not Quant!) related add-ons, not all of which are by Qwant.
Quite aside from this, there is zero need to use an add-on, just visit https://qwant.com/ (or whichever other site) and add the site to your search preferences via the OpenSearch mechanism.
