Links of the bottom of the "Advanced Search" page are on top of the select boxes

Question

In that position the bar of links
"Google Main Page Ad programs Business Solutions Privacy and... Everything About Google"
covers the select box at that position (either "domain or website" or "language" or "region" etc.).
If I push the lower margin of the window upwards making the window smaller, the bar of links moves upwards uncovering the select box hidden under it and covering another select box further up. I can go all the way up till it covers the text boxes "all these words" or "exact sentence".
I have uninstalled Firefox and installed a new Firefox. I eliminated all cookies and caché. I disabled all plugins. I restarted and I also opened in safe mode, but it keeps happening.

Looks that this is caused by setting the height of the div.bottom-wrapper to 100% and that causes the div.bottom-links-wrapper to appear at the wrong position (i.e in the middle of the page).
If I disable the height: 100% !important rule (why even an important flag?) with the Style editor (Inspect Element) then the page appears correctly.
<pre><nowiki>div.bottom-wrapper{
min-height:100%;
margin:0 auto -60px;
height:auto;
height: 100% !important
}</nowiki></pre>
This rule in userContent.css or Stylish should fix this.
<pre><nowiki>@-moz-document domain(www.google.com){ div.bottom-wrapper { height:auto!important; } }</nowiki></pre>
The customization files userChrome.css (interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.
