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!

in case you're an avast user, please try to disable https scanning within avast:

  1. Open the Avast dashboard on the affected system.
  2. Select Settings from the left sidebar menu.
  3. Switch to Active Protection.
  4. Click on Customize next to Web Shield.
  5. Uncheck the "Enable HTTPS Scanning" option and click ok.

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
