I’ve fixed this – please don’t worry about answering.
There are no console errors – the elements are simply unresponsive.
You can’t click on a cell to edit, or click on a heading to change the size of a cell.
Also the splitter is unresponsive. It highlights as the mouse moves over it, but will not drag.
I’m trying this on Fedora Core 21.
It now also doesn’t work in the latest version of Chrome for this platform (Version 48.0.2564.8 dev)
I can’t edit cells, or resize columns.
Do you mean it works for you? Or that you don’t have Firefox 42 (Linux) to test it with?
