Identify Safe Tool Bar Comes and Goes from Internet Explorer

I have been using Identify Safe for over a year now on IE9 without an issue.  I for the past three now, I noticed the Identify Safe icon on my tool bar is no longer there.  I click on the tool bar and it is not shown on the list of items to turn off/on.  I have also looked  on this site and looked into the internet options, advance tab to confirm that third part extensions is selected.  One in a few days, I would briefly see the identity safe on the tool bar, but then goes away again.
