Topic headings not showing in Firefox, with RoboHelp HTML version 8 WebHelp

Question

1. I have just upgraded a customer's Help project to RH8, with a WebHelp layout.
The finished WebHelp Guide works fine in Internet Explorer 8.
But Firefox 3.0.1.5 (latest update) does not show topic headings (style Heading 1) where they are automatically linked to the Topic Properties > Topic Title.; i.e. the topic heading is a Field {Title}, using rh-variable_start name="title" etc. Firefox only shows the topic heading if the heading exists as text in the WYSIWYG field.
I checked a backup copy of the compiled WebHelp that I had generated using RoboHelp HTML version 7, and this works OK - all topic headings that are fields display OK in Firefox.
2. Also, some images (.gif format) do not display in Firefox that is generated by RH8.
Any ideas, anyone?

Hi,
Note: All I post here are my findings. I didn't test all DHTML effects and I'm not a javascript guru, so I may be wrong.
As far as I can find, this behaviour is defenitly a bug, although  it's not related to headings, CBT's or images. This is what I found:
Whenever you have multiple DHTML-effects that kick in on load, Firefox only displays the one that is defined first in the topic. In the bottom of the topic, you'll find a script like this:
<script type="text/javascript" language="JavaScript1.2">//<![CDATA[
    if( typeof( InitEffects ) != 'function' ) InitEffects = new Function();
    InitEffects('img1','x-on-pageload: fadein();');
    InitEffects('h11','x-on-pageload: fadein();');
    InitEffects('h111','');
//]]></script>
In this case, the image with id img1 is loaded first and displayed correct. All subsequent effects (heading with id h11) is not displayed. Putting the heading in front of the image will show the image, while the image is not displayed.
I suspect that the effects are not correctly parsed into
if ((gbBsNS6)&&(srcObj.addEventListener))
        srcObj.addEventListener( noOn.toLowerCase(), new Function("event", newHandler ),false);
on line 2994 and 2995. Changing or deleting line 2995 effectively removes kills on load effects (ie not showing anything with an on load effect) as expected.
If you also use DHTML effects and find the same behaviour as Philip, please post a bug report.
