I am getting an issue wherein I am using FCKEditor, and once I type in something, in the source of FCKEditor, something like below is getting iserted automatically.

<input type="hidden" id="gwProxy" /><!--Session data--><input type="hidden" id="js开发者_如何学编程Proxy" />
<div id="refHTML">&nbsp;</div>

Some hidden tag is getting inserted, which isnot getting diplayed here in my question. Can anyone tell me about this. Thanks in Advance

This seems to be a FCKEditor/CKEditor and Firefox specific issue described here in conjunction with the browser highlighter add-on.

According to the post, disabling that add-on will fix the problem.
