When favicon isn't on page's sourcecode

[nitrocell]

There are sites where favicon isn't on the sourcecode

just as

/favicon.ico

in domain root

Like "rarbg.to" and many others

Can you create a rule to search for /favicon.ico by default?

Found that one too,

On the example: https://pixabay.com, it will fail to grab:
<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">
