Custom About Modules Favicon

I am creating custom about modules with this technique here: http://stackoverflow.com/a/24919721/1828637

The tab gets a favicon but when switching to tab, in the awesome bar dropdwon it does not get a favicon as seen in image here:

Does anyone know how to get icons to show here?

Blah blah blah, browser version, other addons. More relevant, is e10s available/enabled in your browser? What about anything being logged to the browser console (ctrl+shift+j)?

Thanks for the quick reply @arenlor but even about:accounts that tab has favicon but not when switchng to it from awesome bar. Maybe this is a bug for bugzilla?

It probably has to do with the “about:” pages being ignored by history aswell.
But whether the missing favicon is intentional…
I’m guessing a bug.
