Bug in Norton Safe Web v184.108.40.206 for Firefox - Grey Icon on Landing Page
There appears to be a bug in the new Norton Safe Web v220.127.116.11 extension for Firefox.
Every time I launch Firefox, Norton Safe Web is unable to retrieve the site rating for the original landing page - i.e., the site rating icon is a grey question mark. Every time I open my browser the site rating for my home page (https://www.google.ca/) is displayed as a grey question mark, but the icon turns to a green check mark after I refresh the page. I use FF ESR v52.5 but SGFC has reported the same issue with FF v57.0 in the thread Norton Security Toolbar as Legacy Extension in Firefox.
It's not just my home page that's an issue. If I click on the hyperlink in an e-mail notification to view the latest reply in a thread I'm following in the bleepingcomputer forum, for example, and it launches a new instance of Firefox I see a grey icon:
...but I see the green icon if I paste the identical URL (https://www.bleepingcomputer.com/forums/t/648063/security-updates-for-vista-after-end-of-support-windows-server-2008-patches/page-6#entry4384079) in a new tab:
