The popular Chrome extension Microsoft Autofill does not work in Orion.
When trying to "sign in with Microsoft" with a valid account in the pop-up window when clicking on the extension:
a new blank page opens and an empty file named "nativeclient" is downloaded instead.
This extension would be very useful especially as Orion lacks the essential Safari feature allowing to autofill forms with contact and credit card information on web sites.
The pop-up window of the extension should proceed normally after log in, like in Google Chrome:
Version 0.99.127.2-beta (WebKit 619.1.1)
macOS Sonoma (14.4.1)
iOS and iPadOS 17.4.1
