Hi Gulshan,
as you can see one extension is activated. This is the one from version 6.7.0. As written before I manually installed this from the Website after version 6.7.1 from the App Store didn't work. Now I'm using 6.7.0 - but the extension is twice in Safari. Can't uninstall the extension without uninstalling the whole app. So, I'll need to wait until you get this problem fixed and I can re-install 6.7.1
