There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

I had no problem with the link.

Would that indicate that I have something checked improperly in my settings? And if so, what could I look for (not being a computer guru).

Check out the links I posted.

I can get on every other site I need. Not worth spending half a day or more on a site I may not use for months. Thank you for your time.

Hi jinkem, the problem is an incomplete certificate chain. Firefox requires that sites send all the intermediate certificates necessary to connect their own site certificate with a trusted issuer that is pre-installed in Firefox. (Diagnosis: https://www.ssllabs.com/ssltest/analyze.html?d=www.jazzalley.com )

The reason Fred and I can visit the site is that our Firefoxes cached the intermediate certificate when we visited some other site, so even though the site doesn't send it, we're okay. Unfortunately, that is not true for your Firefox. For whatever reason, it has never seen the missing certificate before (or at least since your cert9.db file was created). I can emulate that by creating a new profile, and then I'm unable to connect.

This is sort of a difficult problem to solve because I don't know how to figure out what site you would need to visit to get that certificate. It would be great if the site were to fix it (please suggest it to them).

Meanwhile, if you don't exchange sensitive information with the site, you could create an exception. Click the "Advanced" button on the error page to access that feature. I don't recommend exceptions for site where you need to send or view sensitive information.

Thank you jscher2000! That worked. I'll remember the "sensitive information" advice; a good reason to have someone else put the tickets on their credit card (grin).
