Certificate warnings in Firefox for iOS

By default, Firefox keeps your information safe by warning you when a website’s connection is not secure. If you’re certain that you want to access a potentially unsafe website, Firefox now offers the option to let you bypass this warning on your iOS device.

Do this only with sites that you trust.
  1. When you see the warning page, tap Advanced.
    advanced cert error ios
  2. Tap Visit site anyway.
    override cert ios 4.0
To prevent certificate warnings in the future, contact the site owner and ask them to fix their certificate.
