Hi,
I am able to reproduce the missing favicon for the second website in release 88, beta 89 and latest nightly 90.0a1 (2021-05-25). This is not a recent regression since I am able to reproduce it in Fx70 as well.
Thanks for your input.

The pixelated favicon is likely another case of https://bugzilla.mozilla.org/show_bug.cgi?id=1262982

politico.com seems to have a quite strange behavior, their <link rel="icon"> tags point to .pngs that in reality are html with <figure> tags... I think that's not expected, indeed the type of those is set to image/png, but they are not.
The only real image is <link rel="shortcut icon">, it's possible Chrome is just stopping at this first one, while we try to examine all of them and pick a different one (likely) to better adapt to the screen dpi. If they'd fix their favicons to be real images the problem would be gone.
They also have a mask-icon that should be an svg, but it's not.
I think this a problem on their side, for now we prefer to not support all the possible edge cases with broken websites, unless it's a very common issue affecting many pages.
the 1passwords icon looks ok in my system (but I'm testing on Windows with 125% dpi), the page doesn't provide its own icon, thus we fallback to https://app-updates.agilebits.com/favicon.ico that is a 48px icon. It looks pixelated due to Bug 1402250, that is a problem tracked in bug 1262982 already. Bug 1081224 may provide a solution.
