Norton green ticks have disappeared from Mozilla

Hello all,

 

I'm using IS version 20.5.0.28. I use Mozilla Firefox browser, and usually search with google. Until today the Norton green ticks have been present in my searches, but have now disappeared. I have looked at other peoples' issues with this and can't find anything exactly comparable. I had a long history of difficulty with this problem in IE, which prompted me to change to Firefox.

 

Any ideas?

 

I've tried refreshing the search.
