There seems to be something wrong on the Outlook servers. Hopefully they fix this quickly on the server.

This looks like a problem with OCSP stapling on the server because it works when I disable OCSP Stapling in Firefox.

You can temporarily toggle this pref to false on the about:config page to see if disabling OCSP Stapling works for you. It is best to reset this pref via the right-click context menu to true once you are done with the this website.

• security.ssl.enable_ocsp_stapling = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

Thank you var much, that fixed the problem, now if I just knew which setting in their is causing the javascript error in ebay and usps i would disable that as well. lol The microsoft servers might be messed up on the ocsp, but so is firefox for putting me in the middle of them and microsoft and taking up 2 hours of my time for this, so thank you vary much again.

It is possible that they signed the OCSP response with a certificate that Firefox can't chain to a built-in root certificate.

Can you tell more about the JavaScript issues?

Is this about a script slowing down Firefox?
