>I have a weird issue with Firefox. I am using 45.0.1. The certificate on a specific site is all ok. This has been tested by numerous people, from various browsers. I also see it ok with IE, Chrome and Safari. But, with Firefox, it says connection is not secure. So, I cannot access the site. Others are using Firefox with the same version and they do not have that. I did a factor reset and this did not change anything. Anyone would have an idea what I can try to reset this weird setting that blocks Firefox from being able to access that site?

Clicking on the 'Advanced' button of the error dialog should give you more information as to why Firefox is rejecting the certificate....
