xsl:copy-of working oddly?

I'm relatively new to XSLT however I've noticed something weird.

I'm storing HTML in my XML for a content portion (probably not a great
idea but I need a flexible input type area). My XML looks as such: (in
the actual code content has 4 separate <p></p> groups with Lorem Ipsum
text inside)

---
<content>
	<p>Lorem ipsum dolor sit amet, *snip*</p>
</content>
---

And my XSL file looks as suh:

---
*snip*

<p>Lorem ipsum dolor sit amet, *snip*</p>

<xsl:copy-of select="content/node()" />

*snip*
---

Everything renders properly in IE 7. The paragraphs are formatted
properly and the links are clickable.

HOWEVER, in Firefox (3 Beta 5 specifically) the paragraph in the XSL
(exactly the same tags as the first paragraph in the XML) is rendered
properly, where as the paragraphs included via the xsl:copy-of are
rendered very oddly. Font and color styles are applied, but display,
padding, margin, etc. are not. As well as the links :hover and other
properties work, but they aren't clickable.

Using the web developer tool bar to view the generated source,
everything looks as its supposed to (other than the paragraph tags
being given xmlns="" attributes).

Any ideas?
