I have the Bitdefender TrafficLight for Firefox v3.1.3 extension (https://addons.mozilla.org/en-US/firefox/addon/trafficlight/) installed in my Firefox v81.0.1 browser. I recently noticed that Search Advisor does not work when I search with Google in my Firefox browser (i.e., the green/yellow/red site rating icons are not displayed in my Google search results). The problem occurs when I search at both google.ca (I live in Canada so this is my default search engine) and google.com. I am not sure if this is relevant, but I updated to the current Firefox v81.0.1 on 01-Oct-2020 (see the release notes at https://www.mozilla.org/en-US/firefox/81.0.1/releasenotes/), which is about the same time I noticed that my Search Advisor site rating icons were missing from my Google search results.
Please note that Search Advisor appears to work correctly if I search with other search engines like Bing or DuckDuckGo from my Firefox browser.
I’ve confirmed that Search Advisor is enabled in the extension settings and tried removing / re-installing the TrafficLight for Firefox extension but this didn't help. The TrafficLight icon still appears in my browser toolbar when I browse to individual pages (see image below) so the Web Protection feature still appears to be working.
