After updating Windows 10 to 1809 (October update), the BW extension in edge is definitely broken. The vault is still there, but clicking the toolbar icon simply opens a new Edge window with the vault in it, rather than the usual dropdown.
Further, the page which opens simply says “There are no logins available, etc…”. If I click on “My Vault”, the vault is available, but there’s no way to autofill.
Extensions are small programs that can be used to add new features to Microsoft Edge or modify the existing functionality. Sometimes it creates problem after you update your Windows 10.
