Disable OpenSearchDescription

Hi!

I made my search engine link for the site via “chrome_settings_overrides”.
But the site provides its search too in the open format.


Many information about adding OpenSearch to site. But nothing about how hide it via Firefox addon from Search Bar.

For example, this site. All the time its icon appears with an add (+) icon in Search Bar. I need hide the site’s search icon, because I provide mine.

There is node in page’s head.

`<link rel="search" type="application/opensearchdescription+xml" href="/opensearch.xml" title="MDN Web Docs">`

I tried to delete or change it via JS, but without result.

`document.documentElement.innerHTML = document.documentElement.innerHTML.replace("application/opensearchdescription+xml", "dymmy");`
