Starting with a recent version of firefox, rich-text or WYSIWYG text editors no longer cause firefox to automatically spell check. Users needed to right click and select "Spell check this field" every time they went to a page with this type of editor.
The solution is to add the following line of code into the text editor:
gecko_spellcheck : true
For example, in tinyMCE, the code block might look like:
<SCRIPT LANGUAGE="JavaScript">
<!--//
tinyMCE.init({
gecko_spellcheck : true,
theme : "advanced",
mode : "exact",
elements : "body",
theme_advanced_layout_manager : "SimpleLayout",
theme_advanced_toolbar_location : "top",
theme_advanced_buttons1 : "fontselect,separator,bold,italic,underline,strikethrough,separator,bullist,numlist,outdent,indent,separator,link,unlink,separator,justifyleft,justifycenter,justifyright,justifyfull,separator,hr,sub,sup,separator,code,separator",
theme_advanced_buttons2 : "",
theme_advanced_buttons3 : "",
auto_focus : "body"
});
//--> </SCRIPT>
In looking for this solution, I found MANY people with the same problem I had. If this helps you, please post a comment in my blog.
