hi aaron, https://www.ssllabs.com/ssltest/analyze.html?d=paperbear.ie is showing issues for your site as well. firefox uses ocsp for checking the validity of a certificate: https://en.wikipedia.org/wiki/Online_Certificate_Status_Protocol by default, and this is where your site is failing. you'd have to get in contact with your host and/or comodo, your certificate's issuer to inquire what is going wrong here in detail...

Thanks so much Philipp. So do you think its just a SSL issue and nothing to do with the website itself?

yes, nothing particular with the site itself - at the moment it seams to load fine again btw :-)

but do you see the padlock symbol with the i beside it? It means firefox is blocking certain elements of the website. This could be a bit of problem.

Actually i think its the mixed content that is the issue. Thanks again.

You can see a special padlock at the left end of the location/address bar.

• a padlock with a strike through means that mixed active content is blocked.
• a padlock with an exclamation mark attached means that mixed passive content (e.g. images) is present, but not blocked.

The shield icon, previously used for mixed active content, is now used for Tracking Protection.

You can check in the Web Console ("3-bar" menu button or Tools > Web Developer) what content this is about.
