Firefox will no longer let me access my Yahoo mail due to a certificate problem, and it will not let me add an exception. How do I get into my email?

I have been using this computer and firefox to access my yahoo mail for like 4 years now, but today it decided to stop allowing it, due to a problem with the security certificate. It says: "This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate." I checked my email successfully early today, but now I can't. I can still get it with internet explorer, but not firefox. How do I fix this?

Hmm, I've never seen that particular message before. Does the error page have the usual "Technical Details" section? If so, could you expand that section and copy/paste what you find there into a reply?

Take easy and follow some steps: 

click on link: mail.yahoo.com

if not opening then can you find there a notification like "blocked" if yes : Click on that and then select continue without block or any option like that. Then click the upper yahoo link again . if you succeeded ,please click on solution, if not Edited out by a Moderator, please do not advertise for work [edit} Please continue the thread using /questions/1038806#question-reply ~J99
