Almost every website I visit, including Bing search, gives me an "Insecure Connection" error code!!!
I have no idea what's going on. I have the latest Firefox Developer Edition English x64 and every website I try to connect to, Google, Bing, etc. give me this insecure connection error. I also have Chrome, Vivaldi, Edge & Opera browser and none of them give me issues like this.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

Click on the Advance and expand it so there is a certificate information that looks like a bunch of letters and such. Post that in chat so somebody can decode it and tell you what software is likely doing this. It is likely say a antivirus client inserting its own man in middle certificate if you have feature enabled in the client.
