Norton Toolbar missing in Firefox 48 web browser in Win'8.1

I had to recover my OS afresh recently, so Windows 8.1 installed on my notebook from a clean slate. However, though Norton Security Standard 22.7.0.76 got installed properly and also got activated on the system, it hasn't installed the Norton Toolbar on the Mozilla Firefox 48 browser. The same is installed on Google Chrome browser and IE though. How do I get the Norton Toolbar on Firefox, and also search results in Google Search don't show the Norton icon at the end (assuring safe site to access).

Will be grateful if someone can guide me on the above. Am not a IT expert, so pls excuse my crude writing ;-)

Thanks
