adding <link rel="icon" type="image/png" href="data:image/png;base64,iVBORw0KGgo="> seems to solve the issue. If I got it right, I can open data:image/png;base64,iVBORw0KGgo= in browser, save it as favicon. ico aka. empty PNG file and store it in website root.
Clear your browser's cache. make sure favicon. ico has physically been deleted from the root, if it was there in the first place. Some browsers will search for it there even if it is not mentioned in your HTML.
This known as the 'favicon. ico' and is typically fetched from website.com/favicon.ico. Your browser will automatically request it when browsing to different sites. If your browser receives a valid favicon.
The favicon. ico file is a small graphic icon that is used by some browsers (including Microsoft Internet Explorer and Mozilla Firefox) to enhance the display of address bar information and "favorites" bookmark lists.
You probably have such a line (most likely in your application.html.erb, or some other template):
<link href="/favicon.ico" rel="shortcut icon" />
If you do, just change it to:
<link href="/assets/favicon.ico" rel="shortcut icon" />
