Is web shield working in Firefox Beta 23 even when icon in menu is missing?

The extension is installed and Avast says web shield is working and my computer is protected, but the icon is not in the menu bar of Firefox Beta 23, so I wonder if it is working or not!

Hi there, the icon you’re talking about is WebRep not being there. Web Shield protects your browser silently. WebRep is just how people think how safe the website is.

Cheers,
