Update to 22.7.0.76 removes Norton Toolbar & Safe Search from Firefox?

My Norton Security product has just updated itself to version 22.7.0.76

Following a restart Norton prompted me to activate security add-on's for Internet Explorer.  However I use Firefox version 47.0.

Once I started Firefox I found that Norton Toolbar and Safe Search had been removed.  Not even listed in the available Add-On's or Extensions.  How can you arbitrarily enforce an update that removes important security features from my browser of choice.

How do I go about re-enabling both the Norton Toolbar and Safe Search for Firefox.  Please! 
Or, is it possible to go back to the previous Norton Security version?

Thanks.
