The favicon appears broken upon opening a new tab

Usually, I use a favicon PNG file for my website. It works perfectly and I can see my favicon on the browser tab.

However, when I open a PDF document in a new page from my Angular app, I notice that there is a broken icon on the browser tab. Here is how I trigger the opening of the PDF document:

<a href= "{{getRegulamentoFile()}}" target="_blank" rel="noopener" style="color: var(--wb-blue-45)"> PDF Document </a>

Answer №1

The reason for this occurrence is that the favicon is specifically associated with HTML pages. When displaying a PDF file, your browser lacks the necessary information regarding the website's favicon and has to make do without it.

It is important to note that the icon you are seeing is not technically "broken"; it may have been fetched from another source. If you are running your application locally through localhost, the icon could potentially be sourced from a different project you have worked on in the past.

There is no definitive solution to this issue; rather, it often involves trial and error. One common approach is to ensure that the /favicon.ico file is present along with all other favicon images (e.g.,

http://localhost:3000/favicon.ico
). Following this commonly accepted convention can help browsers navigate these situations more effectively.

Answer №2

When you insert HTML containing a "Link" to ICO and Frame(s), the HTML Icon and Title will be utilized, even if it doesn't belong to you. This means it is "Linked" (Icon nabbing) to DuckDuckGo, and the framed PDF(s) can be linked elsewhere as needed.

By linking a browser tab to any site frame, regardless of what it may be, like a _blank tab, the browser will provide its own LOCAL Document Icon and Title (if one is assigned for that mime doc type).

This creates a similar issue whether or not there is carrier HTML present.
