Browsers such as Chrome request "favicon.ico" by default.

If you are working on some site that does not need a favicon, here are some workarounds.

1. add the line: <link rel="icon" href="data:,"> to the head of all your html files

Since you mentioned settings, here are a couple things you can do to quickly get rid of the 404:

2. Chrome Network tab -> right click "favicon.ico"

• select Block request url [you can disable this later]

3. Live Server settings > Settings: File

• enter some other default file or / [dangerous, not recommended for this case]

Keep in mind, the last two solutions will likely catch up to you if you actually want the default behavior to let you know when you did not add a favicon.
