Mozilla currently generates tons of DOM #text nodes which contain nothing
but white space.  For instance, typical HTML like

<html><head></head>
<body>
<p>blah blah blah</p>
<p>another paragraph</p>
</body>
</html>

will generate five unnecessary #text nodes, one for each of the newline
markers.  This is easiest to see by loading up a simple page in the DOM
Inspector.  Compare the above with

<html><head></head><body><p>blah blah blah</p><p>another paragraph</p></body></html>

where everything is on a single line.

Mozilla should delete all leading and trailing whitespace from #text nodes
and then discard #text nodes which turn out to be empty.  This will give
the desirable property that the DOM tree for a document is independent of
where the author chose to break lines.  It should also save memory.
Known bug/issue.
