User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:79.0) Gecko/20100101 Firefox/79.0

Steps to reproduce:

1. Open Firefox
2. Open a tab and type in the address bar https://bitwarden.com/
3. Open a new tab and type in the address bar https://1password.com/

Actual results:

Bitwarden's favicon looks good, but 1password doesn't.

Expected results:

Both favicons look good.

I think the issue is that Bitwarden is not using:

<link rel="shortcut icon" type=image/x-icon href=/icons/favicon-v1.ico>

but only uses favicon in PNG format.

I think the issue is that Bitwarden is not using:

<link rel="shortcut icon" type=image/x-icon href=/icons/favicon-v1.ico>

but only uses favicon in PNG format.

So... what would you suggest Firefox should do about that? It sounds like the site needs to fix their icon?

For example, Firefox could use the favicon in PNG format with the highest resolution.

<link rel="icon" type="image/png" href="/img/favicon/favicon_16.png" sizes="16x16"/>
<link rel="icon" type="image/png" href="/img/favicon/favicon_32.png" sizes="32x32"/>
<link rel="icon" type="image/png" href="/img/favicon/favicon_96.png" sizes="96x96"/>

In this case I would use favicon_96.png.

It would be nice to use the favicon in SVG format.
