FF 59.0.1 with Enpass Addon 5.5.2 not working

[pout]

Hello,

Win10 Pro
Enpass Desktop 5.5.6
Firefox 59.0.1

I have installed Enpass 5.5.6 through the windows store. Downloaded and installed the EnpassNMHost.exe. The Browserextension is activated in Enpass Desktop, but I get an Enpass Connection Error: "Enpass extension is not able to connect with the Enpass app. " when calling the Broserextension.

The Browserextension in Edge and Chorme is working.

The Winuser is a Standarduser, no Admin-account.

Any Ideas? Thanks Roman

My workarround was making the user to an Domain-Admin, installing EnpassNMHost.exe and then removing user from Domain-Admin group again. Now the FF-browser-plugin works.
