This extension works very well and I love the way it works, couldn't be more happier. The only thing that won't work for me is HTTP Basic Auth. According to documentation, it should work, but I don't know how to do it. When I'm presented with a basic auth form, nothing happens on the extension's side. No way to trigger it, to auto-fill, to summon the extension's dialog to choose a login... And I couldn't find anything in the documentation on how to enable HTTP Basic Auth to work with KeePassXC-Browser.
Added: Thanks! That worked.
