Hi Holger.  I've updated the X3dToX3dom.xslt stylesheet and X3D-Edit to support your latest version 1.24.  Works great in Windows 7 in latest Firefox v45.0.1.

Conversion result attached.  Wondering if it is correct since failures are occurring in other web browsers.

Unfortunately, other browsers fail and have similar errors, apparently cross-origin scripting restrictions.

Console excerpts follow.  Please advise, am thinking this is a common problem that someone on the mail list may be able to help with.

============================================
Internet Explorer "Edge" gives the following console error:
DOM7011: The code on this page disabled back and forward caching. For more information, see: http://go.microsoft.com/fwlink/?LinkID=291337

============================================
Chrome console reports a similar error:

Opera also reports a similar error:

We are not inventing new functions.  Instead, the stable code base of Cobweb makes it possible to run in different browsers.

Second, »FourmiEarth« processed data from the well known Fourmilab website, to display a pleasant view of our home planet.  Third, »Currencies« processes data of the currencies data of the European Central Bank, to show a nice animated graph of it. To do this we draw thick 3D lines using an Extrusion node.
