TinyMCE problem with Expression Engine in Firefox

I just encountered a problem installing the TinyMCE editor on an install of ExpressionEngine – all the files were uploaded correctly and the extension to get it working in ExpressionEngine was uploaded and properly activated, but the editor wouldn’t appear in Firefox 2 (other browsers were fine).

I found the solution to the problem at Tis How I Code. There’s also some further discussion of the issue on the Moxiecode forum.
