Forum:Problem: indents not displayed

If (using Firefox 3) find indents are often not displayed e.g. seen in edit http://community.wikia.com/index.php?title=Forum:Problem:_wiki_title_case_not_respected&action=edit but not in display http://community.wikia.com/wiki/Forum:Problem:_wiki_title_case_not_respected. Is it just me? Anyone know a fix? Chrisjj2 :)
