Have to admit that it makes it appear that an app that has a potential to draw financial support seems to get more attention to keep it working and available than one that doesn’t. Interesting that the Extension Warehouse, more than likely using the same outdated built-in browser that 3DW would be using as previously noted, seems to function fine. Access via the component toolbar doesn’t work either and scrolling the component panel is a PITA. Just my 2 cents (or 2 bits adjusting for inflation) wanting to note another user is having the same problem trying to access the warehouse thru SU17 application and just getting the virtual blank page.
