Difficulties in using ID Safe entries

Hi all,

Frustrating though it is, I understand the importance of getting the ID Safe feature safe and secure before updating to FF v.43 compatibility.  It wouldn't be too painful, if I could use the temporary arrangement as I understand it should work.  I hope you're still with me.

When I open up the ID Safe log in and log in, I get the list of log ins.  I understand that I should then be able to click on the arrow at the right hand side to bring up the relevant web page and auto-fill the log in and password.  When I try this, I get the right page, but it just sits there, empty, and I have to input login and password manually. 

Have I got it wrong, or is there some setting I've got to change to get this to work?

Thanks,

Ian
