Links to id's and named anchors within a page in an iframe do not open in firefox

Question

In order to force layout of my liquid website, I use i-frames to display content . It is all on my sight www.rdelutherie.com, and I am not displaying pages from other sights. The links to sections of pages from within the same page do not work in firefox.
I have had this problem before with named anchors, and in moving up to html5 and in making my site accessible for people with dissabilities, I started using <nav> eliments... and changed from named anchors to links to ID's like this:
In an unordered list I have these:
<pre><nowiki> <li><a href="#s1">Subject 1:</a></li>
</nowiki></pre>
They link to sections of the same page like this one:
<pre><nowiki>
<section id=s1>
<h2>Subject 1:</h2>
<p>Blah blah blaaaaah, and bla bla!</p>
</section></nowiki></pre>
Last time I researched this problem (a year or more ago), I was told that it was because of a security risk (something about being able to count views...and other peoples proprietary and copyrighted material), but the vaguely described reasoning made little to no sense to me nor many others, who can not even link to our own stuff. The Mozilla developers were rather abrupt and some were even rude in telling us to live with it, instead of trying to come up with a solution or work around, and closed the post and disallowed further posting.
The problem still persists, and although I am not a programmer, I have a real hard time believing that it is impossible for Firefox to distinguish between links contained within a document and site, from those on different sights, domains and what have you.
As far as I know, no other browsers have this problem, so if it is such a big security risk, what is to stop someone with malicious intentions, from just using M$ IE, to bring their evil plan to fruition?
In keeping with "Making the web a better place": Please address this problem, and find a solution, workaround, or at least explain why it is impossible.

Thanks again jscher2000,
I know exactly what you mean, but I have had other page display problems with adjacent columns where one side does not display completely and seems to be conforming to the other ones height... hence the height settings and other tricks to force things to be acceptable.
I am far from understanding code, and most of the solutions, including the one in the link you posted do not have the information a novice like me would need to implement them successfully. Most of them are written for people much more advanced. Without it telling me where exactly to put the code, point to it, what I can (and should) change and remove elsewhere because of it... I am at a loss. I don't know the basics, and have tried hard to understand them, but it is not like electrical circuits, physics and other things that I can understand naturally and with ease.
I will look into it further in a few days, meanwhile I have to attend to my real work that doesn't even pay the bills completely: guitar building and repair, now that comes easy and naturally to me!
