Frame id not recognized by javascript in firefox 8.0

I have a frameset that includes a frame with id="main" When I click a link that invokes javascript referencing top.main it comes up as undefined. This code runs perfectly well in IE, in Chrome and on Android Tablets.

I guess I will have to tell my users to use one of those browsers instead of Firefox.

The code in file tophelp.htm is:

<frameset cols="162px,*">
<frame noresize="noresize"  style= "border-right-width:thick; border-right-color:Maroon;" id="contents" src="navhelp.htm" />
<frameset rows="30px,*">
<frame frameborder=0  id="mainhd" marginheight="3" marginwidth="8" src= "Helphead.htm" />
<frame frameborder=0  id="main"   src= "Helpmain.htm" />
</frameset>
</frameset>

A JS function in this page has code:

top.main.location.href = "HelpOverview.htm"

This code generates an error: top.main is not defined.

Use name instead of id in the frame and use window.top instead of top.

You probably need to include the protocol as well.

window.top.main.location.href = "http://HelpOverview.htm";

<frameset cols="162px,*">
<frame noresize="noresize"  style= "border-right-width:thick; border-right-color:Maroon;" name="contents" src="navhelp.htm" />
<frameset rows="30px,*">
<frame frameborder=0  name="mainhd" marginheight="3" marginwidth="8" src= "Helphead.htm" />
<frame frameborder=0  name="main" src= "Helpmain.htm" />
</frameset>
</frameset>

Try posting at the Web Development / Standards Evangelism forum at MozillaZine. The helpers over there are more knowledgeable about web page development issues with Firefox.

Changing from 'id' to 'name' did the trick. Thanks.
