@Dirk-Stadtherr Hi Dirk, Unfortunately, it may happen to have dead ends in the roundtours. But, you can tweak those roundtours yourself :). You can move, delete and add markers to the roundtour. Move the marker by dragging the marker, delete the marker by clicking on the marker and a popup appears, and you can add a new marker by clicking on the line. Concerning the layout on firefox.. that indeed needs to be fixed. We will have a look at that. Thanks for mentioning!
