Windows 10, Firefox,.
Have exactly the same issue. Preview of the PQ map takes me to my home location not the location of the PQ. The same happens when selecting the PQ from the map drop down list. Not tried the leaflet option.
*Update* Well that was strange went and tried the Leaflet map option and it worked as per normal, switched to Google maps and it's working. Closed down Firefox and tried again and it's working..... isn't IT wonderful.....
*Update 2* It's lost the plot again....!!
