Yes, and Hi, Firefox now longer gives your program the required permissions to have entry to those files that would run this due to changes in 57+ for Firefox Security. Norton had the same green tick in Safe Search, It is now run from a Extension that uses a Search Engine from Norton Ask.com.

Update:

I now have green ticks back on Firefox, Chrome and Microsoft Edge. They reappeared after uninstalling Bullguard via control panel, not keeping original settings and then reinstalling it. I had previous uninstalled it, but through a download link which didn't seem to give the settings option (unless I missed it). I did have to reinstall Chrome to get the ticks back there.
