Refresh Parent From IFrame Makes Refresh Loop In FF Only?

I have this code in a page that appears in my iframe if requested from parent:

<script type="text/javascript">
parent.rrr();
</script>
The parent code is:
function rrr() {
javascript:location.reload(true);
}

So, the person clicks a link from the parent, it does a php process in a hidden iframe, which then tells the parent page to refresh. The only problem is that it puts Firefox in a constant loop of refreshing. IE and Chrome work fine. They refresh once and stop.

Though the src code opens the iframe like so: <iframe src="" style="display:none; height:1px;" name="hdplus" id="hdplus"></iframe> Firefox seems to refresh the page with the memory of the child page being in the iframe, constantly looping the child request to refresh the parent.

Why won't Firefox just accept that no page should load in the iframe, as stated in the code? I need to stop this loop, which means I need to get firefox to reset the iframe as it reloads the page.
