Favicons are now supported natively by SearXNG! Thanks to @vojkovic for the implementation! This extension is currently broken by the latest version of SearXNG and there will be no more updates.
Warning
This is considered a bad practice by SearXNG maintainers because it can lead to tracking by Google.
Note
This extension may not work on instances that block cross-site images. You may see a warning like this in the logs.
Content-Security-Policy: The page’s settings blocked the loading of a resource (img-src) at <url> because it violates the following directive: “img-src 'self' data: <url>”
