No secure connection issue even after selecting "no proxy"

Firefox Falhas em sites

I decided to start using Firefox again, after ~6 months. Last time I had firefox on Windows 7 it worked fine. I opened it up and it won't load any secure sites at all. I upgraded to latest version, same thing. I went to my connection settings, for some reason "no proxy" wasn't selected, I've never used a proxy, though. I selected "no proxy", restarted, and the problem still persists. How do I fix it?

Thanks!

hi, what kind of error messages/codes are you seeing when attempting to connect to https-sites & which security software are you suing on the device?

An error occurred during a connection to apps.facebook.com. Peer's certificate has an invalid signature. (Error code: sec_error_bad_signature)

Thanks for the response. That's the exact message, with the header saying Secure Connection Failed
