Adding Caches to VGPS on the map doesn't work

[markggn]

On the "old" map (on https://www.geocaching.com/map/) there was a button on the popup which opens after a click on the cache to add the cache to VGPS. It seems that this button is gone when using Firefox. It still does work on the listings pages and using Chrome.

Does not work: Firefox 125.0.3
Does work: 124.0.6367.118
