Maps no longer shown on Windows 10 / Firefox

just found a problem: my KML-Maps are no longer displayed on Windows 10 / Firefox, do not know if caused by latest Firefox or Zh GoogleMap.

Typical map example: map on the right of the text on
familie-abderhalden.ch/index.php/reisen/nordsee/2015-norwegen

Maps still are shown on Windows 10 / Microsoft Edge and on IOS / Firefox 23 for IOS.

Windows 10: is up-to-date

Firefox for Windows causing problem: 75.0 (64-Bit)

Zh GoogleMap Version:
Package 11.1.1.0 Status Zh GoogleMap Package
Component 11.1.1.0 Status Zh GoogleMap
Module 6.1.0.0 Status Zh GoogleMap Module
Plugin 6.1.0.0 Status Zh GoogleMap Plugin

What can I do?

I replied you in message. I can see your map with KML. Try to clear browser cache.

Thank you for quick answer.
