It is creats the same result, because we are still using https.
Is there any PlugIn, which informs the user and asks to update the browser?

Thank you for your help! I really appreciate it.
A Snapshot is attached in the private section below. As I said in my post above, the reason for this may be the ssl encryption. I tested other sites with https and they have all the same problem.
Can you recommend a Plugin which asks the user to update or use another Browser?

Kind regards
