Malcolm,

The fact is that CuteEditor does work in Firefox on the Mac - see the screenshot below. I'm using OSX 10.3.9 and Firefox 1.0.3. So you have most likely set it up wrong - maybe you didn't copy all the files you need to your server.

How exactly are you testing this? Are you trying to view the demos on the Cutesoft web site? Or have you set up a web site of your own and are trying it out there?
