Hi Paul, Sorry 'bout the late answer; I don't get emails on responses. My browser is Firefox 45.3.0 running on Windows 7. I use Privacy Badger - that blocks sites that do too much cookie tracing but it didn't object to your page. What may be more significant is that I browse through a corporate firewall - it sometimes fails to connect to the same host I connected through earlier, and sites which rely on consistent conversations sometimes fall victim to this. All that said, frustratingly, today I see colorful splotches. Whatever the problem was, it seems to have gone away. I think that your idea to do more server-side rendering is praiseworthy. I'm very tired of the many Web sites whose authors seem to think they own my CPU.
