Getting a 'Warning:potential Security risk' or a blank white page on many of my HTTPS sites.
But they work fine in other browsers. This is a big issue for me since I use FF all my online banking and personal health sites. Only started a few days ago and nothing I do fixes it. I admit I a computer user so my knowledge is limited.

Thank you FredMcD. Nothing I did following those links helped. So I resolved it by installing the portable version on my desktop. Installed the same extensions and bookmarks and everything is back to normal. Thank you again.

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