It seems our technique no longer works in Firefox. We'll change this in the next patch, but a workaround is to make this change in themes/default/templates/JAVASCRIPT_EDITING.tpl...

FROM...

function do_emoticon(field_name,p,_opener)
{
var element;
if (_opener)
{
element=opener.document.getElementById(field_name);


TO...


function do_emoticon(field_name,p,_opener)
{
var element;
if (_opener)
{
element=parent.document.getElementById(field_name);

Chris, that does not seem to fix the problem. I have checked twice,not including the first modification, and no joy.

Automated response: Overlay context trick not working on Firefox

Javascript windowing context is altered so overlays look like a popup window -- however this no longer works for Firefox. Therefore the templates need to be changed to analyse the context in-situ.

This is the full fix I mentioned on the forum. This will be rolled into the next patch release, due soon.
