I just noticed that you didn’t allow for the default padding and margin on the ul hence the differences in browsers.
e.g.
#endnotes ul {
line-height: 1.3em;
list-style-type: none;
font-size: 0.8em;
[B] margin:.5em 0 0;
padding:0;
[/B]}
#endnotes[B] ul li[/B] {
[B] margin: 0.5em 0 0;
[/B]}
To my mind, footnotes are a print-based convention that we can solve with a different, and better, approach But that’s my opinion, your mileage may vary.
Yes, I don’t like the fact that you lose your place in text when you read the footnote which is why I suggested using :target to highlight where you are going and how to get back.
Perhaps a fixed footer would be a better approach as you wouldn’t lose your place in the text so easily.
e.g.
Roughly like this:

<h1>George Washington</h1>
<p> On April 30, 1789, George Washington, standing on the balcony of Federal
Hall on Wall Street in New York, took his oath of office as the first
President of the United States. "As the first of every thing, in our
situation will serve to establish a Precedent," he wrote James Madison,
"it is devoutly wished on my part, that these precedents may be fixed
on true principles." <sup id="cite_01"> <a href="#note_01" class="reference" title="See End-Note below...">[1]</a> </sup> </p>
<p> Born in 1732 into a Virginia planter family, he learned the morals,
manners, and body of knowledge requisite for an 18th century Virginia
gentleman. <sup id="cite_02"> <a href="#note_02" class="reference" title="See End-Note below...">[2]</a> </sup> </p>
<p> He pursued two intertwined interests: military arts and western
expansion. At 16 he helped survey Shenandoah lands for Thomas,
Lord Fairfax. Commissioned a lieutenant colonel in 1754, he fought
the first skirmishes of what grew into the French and Indian War. The
next year, as an aide to Gen. Edward Braddock, he escaped injury
although four bullets ripped his coat and two horses were shot from
under him. <sup id="cite_03"> <a href="#note_03" class="reference" title="See End-Note below...">[3]</a> </sup> </p>
<p> From 1759 to the outbreak of the American Revolution, Washington
managed his lands around Mount Vernon and served in the Virginia House
of Burgesses. <sup id="cite_01"> <a href="#note_01" class="reference" title="See End-Note below...">[1]</a> </sup> Married to a widow, Martha Dandridge Custis, he devoted
himself to a busy and happy life. But like his fellow planters,
Washington felt himself exploited by British merchants and hampered by
British regulations. As the quarrel with the mother country grew acute,
he moderately but firmly voiced his resistance to the restrictions. </p>
<p> When the Second Continental Congress assembled in Philadelphia in
May 1775, Washington, one of the Virginia delegates, was elected
Commander in Chief of the Continental Army. On July 3, 1775, at
Cambridge, Massachusetts, he took command of his ill-trained troops
and embarked upon a war that was to last six grueling years. </p>
<p> He realized early that the best strategy was to harass the British. He
reported to Congress, "we should on all Occasions avoid a general
Action, or put anything to the Risque, unless compelled by a necessity,
into which we ought never to be drawn." <sup id="cite_04"> <a href="#note_04" class="reference" title="See End-Note below...">[4]</a> </sup> Ensuing battles saw him fall back slowly, then strike unexpectedly.
Finally in 1781 with the aid of French allies--he forced the surrender
of Cornwallis at Yorktown. <sup id="cite_05"> <a href="#note_05" class="reference" title="See End-Note below...">[5]</a> </sup> </p>
<p> Washington longed to retire to his fields at Mount Vernon. But he soon
realized that the Nation under its Articles of Confederation was not
functioning well, so he became a prime mover in the steps leading to
the Constitutional Convention at Philadelphia in 1787. When the new
Constitution was ratified, the Electoral College unanimously elected
Washington President. <sup id="cite_02"> <a href="#note_02" class="reference" title="See End-Note below...">[2]</a> </sup> </p>
<p> He did not infringe upon the policy making powers that he felt the
Constitution gave Congress. But the determination of foreign policy
became preponderantly a Presidential concern. <sup id="cite_06"> <a href="#note_06" class="reference" title="See End-Note below...">[6]</a> </sup> When the French Revolution led to a major war between France and
England, Washington refused to accept entirely the recommendations
of either his Secretary of State Thomas Jefferson, who was pro-French,
or his Secretary of the Treasury Alexander Hamilton, who was
pro-British. Rather, he insisted upon a neutral course until the
United States could grow stronger. </p>
<p> To his disappointment, two parties were developing by the end of his
first term. Wearied of politics, feeling old, he retired at the end of
his second. In his Farewell Address, he urged his countrymen to
forswear excessive party spirit and geographical distinctions. In
foreign affairs, he warned against long-term alliances. </p>
<p> Washington enjoyed less than three years of retirement at Mount Vernon,
for he died of a throat infection December 14, 1799. For months the
Nation mourned him. </p>
