I'm at a US government agency and the system that processes our time and attendance still does not work with Chrome or Firefox - I think it's some kind of security certificate issue? So they tell us to use Edge to fill our our time and attendance. I click some link from our internal home page and it loads up the page in "Internet Explorer Mode," complete with the blue "e" in the address bar.
It's bullshit "security" for banking, it could be that it depends on something that isn't emulated by Edge, like toolbars or some other form of deep browser extensions, not "just" ActiveX.
For all it's worth it could be something as insane as a kernel driver that assumes a certain IE build and hooks into it for "security". Never heard of such things in areas outside of gaming, but won't be remotely surprised. Banking industry is way more backwards than gaming, after all.
