title: Tweet Button and Facebook Like Button appearing below menu bar in FF
body: <p>My problem is that I have a menu bar with z-index 100, and two elements of that bar with z-index 1000 (Sorry, in the code, the z-indexes are actually higher numbers butt different by a factor of 10... i realize this is bad practice, but i havent changed it yet because there are a few pieces connected).  In firefox, the tweet button and facebook button always appear underneath the menu bar.  it works perfectly in all other browsers.  The live example is at my <a href="http://la.truxmap.com" rel="nofollow noreferrer">Los Angeles Food Truck Map</a>.  Here is some of the relevant code:</p>
  <pre><code>        #tweet_button{
              position:relative;
              left:6px;
              bottom:10px;
              z-index:100000000;
              }
  ...
  
      &lt;div id=&quot;smoothmenu1&quot;&gt;
  
  &lt;b id=&quot;tweet_button&quot;&gt;&lt;a href=&quot;http://twitter.com/share&quot; class=&quot;twitter-share-button&quot; data-count=&quot;none&quot; data-via=&quot;truxmap&quot;&gt;Tweet &lt;/a&gt;&lt;script type=&quot;text/javascript&quot; src=&quot;http://platform.twitter.com/widgets.js&quot;&gt;&lt;/script&gt;&lt;/b&gt;
              &lt;span id=&quot;facebook_buton&quot; style=&quot;color:white;&quot;&gt;&lt;iframe src=&quot;http://www.facebook.com/plugins/like.php?href=http%3A%2F%2Fla.truxmap.com&amp;amp;layout=button_count&amp;amp;show_faces=false&amp;amp;width=80&amp;amp;action=like&amp;amp;colorscheme=light&amp;amp;height=21&quot; scrolling=&quot;no&quot; frameborder=&quot;0&quot; style=&quot;position:relative; left:10px;top:4px;border:none; overflow:hidden; height:35px; color:white;width:90px;overflow:hidden;z-index:100000000;&quot; allowTransparency=&quot;true&quot;&gt;&lt;/iframe&gt;&lt;/span&gt;
      &lt;/div&gt;
  </code></pre>
  <p>It may be important to note that I'm using GWT.  I noticed that sometimes, the frame of the tweet button has one of the google ad sense ads superimposed upon it... i'm not quite sure why this is happening, but i figure its probably related to the solution.</p>
  <p>Thanks a lot!!</p>
