Hello, I use yahoo mail for 25 +years; recently I see following note on the right parts of screen. have you changed something in your setting?
Did Not Connect: Potential Security Issue
Firefox detected a potential security threat and did not continue to gpt.mail.yahoo.net because this website requires a secure connection.
What can you do about it?
The issue is most likely with the website, and there is nothing you can do to resolve it.
If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.
