i use the latest firefox version 65.0.2
If i want to open my GUI i get directly a warning popup window

No entry possible.
In Explorer it works but i get a certificate warning in red but i can open it. i am pretty sure that i have installed the certificate, or didn't i ?
What is the problem ?
Did you already used the privacy mode in Firefox or tried to clear the Cache / cookies and offline files?
Yes, both (private mode and cleared Cache) i have tested but with same result
It is more or less mostly the same version und not here and there the latest version, what should be in my opinion no problem. I do not have any clue about this issue what firefox doesn't even try to give my a site and immediatly gives me that popup :-(
