Missing ID Safe Icon from Toolbar

Have installed the ID safe extension to firefox (53.0.3) and no icon is showing on the tool bar. I have the 'Norton toolbar' ticked and is showing safe search ect but no ID safe icon.

Also whatever website I visit the login will not populate, just show the grey 'keyhole' icon. And yes I have logged into the ID Safe so that it should auto fill for that site I visit.

Could someone please advice what I'm doing wrong, thank you

PC details, Windows 10 (upgraded from 8.1) running with fast start-up off, and have done a restart after installing ID safe. Norton Security 22.9.4.8
