Edge Beta 78.0.276.8 - missing favicon in popup windows or in taskbar in Windows
As I have mentioned, it should work, it used to work and currently it is working if I use Google Chrome. So that is also a bug with this release.
I've never seen a website before changing my browser's icon on my computer without my permission. that sounds like a security vulnerability.
No its not security vulnerability as the favicon is supposed to work that way.
Try this link in Google Chrome and Edge C both.

Click on the link and it will open browser window, the favicon should be displayed in the titlebar and in the taskbar of Windows. It is working fine now with Google Chrome Version 77.0.3865.90 (Official Build) (64-bit) on my machine. And it used to work with Edge C Beta Version 77 until I got update to Version 78, it got broke.
So I tested it.
the Red circle is definitely a problem (popup windows don't correctly get the website's favicon)
the pink circles could be also a problem (user might expect to see the website's favicon in those places too but that neither works for popups nor for normal website tabs)
the green circle is definitely Not a problem. websites only have permission to change it if they are added as an app (PWA), other than that, it would be a security issue because they are accessing browser files on your computer.
