TYPO3 Core

This happens only on Firefox 2.0.0.4 under LINUX. It still works with Konqueror and Internet Explorer 6.
When I use another backend user then this bug remains. I do not know how I can get this TYPO3 installation working again with Firefox 2.0.0.4. What could be the reason that the left and middle frame do not get shown?

------------------
the sourcecode of the backend has this:
case 'help_aboutmodules':

top.content.location=top.getModuleUrl(top.TS.PATH_typo3+"alt_intro.php?"+additionalGetVariables);
            top.fsMod.currentMainLoaded="help";
            top.highlightModuleMenuItem("ID_226369394");

This leeds to the result that only the help page http://localhost/typo3/alt_intro.php? is shown in the backend. But how to proceed from here?

If I deactivate the JavaScript in Firefox, then the backend module is shown as it should be.

Delete in class.alt_menu_functions.inc line 303:
top.content.window.location=top.getModuleUrl(top.TS.PATH_typo3+"'.$this->wrapLinkWithAB($link).'"'.$addJS.'+additionalGetVariables);

Then the backend is usable again. However no help page will be shown.

Close this bug. I cannot repeat this. any more.

Now it this bug is back again. - sigh

typo3/alt_main.php:
The id=".." parameter is missing for the frames, only the name is given. So getElementById cannot be used.
Konqueror claims this line as undefined:
case 'help_aboutmodules':
top.content.location

The id for content is missing.

I have copied the not working TYPO3 instance to a test2 instance. Then I have used a working TYPO3 database. Here is the difference in the error_log.

There is a line in the end of function main in typo3/alt_main.php

</html>';

error_log ('SC_alt_main: $this->content='.$this->content);
}

The first error_log is from the not working TYPO3 instance. The second has all the same files and extensions. The only difference is somewhere in the database.

The reason for this bug comes from the line in JavaScript:

top.goToModule('help_aboutmodules',false,'');

This is in function startModule() in alt_main.php

if (!$module)    {
            if ($BE_USER->uc['startModule'])    {
                $module = $BE_USER->uc['startModule'];
The second IF is true on the not working site. Do to some fiddling around it happened that the backenduser has a startModule assigned.

if ($module) {
$this->mainJScode.='
// open in module:
top.goToModule(\''.$module.'\',false,\''.$params.'\');
';
}

This PHP adds the JavaScript, which does not work in Firefox and Epiphany browsers.
This results that only the frame
http://localhost/typo3/alt_intro.php?
is shown, nothing else.

The be_users table for the admin user shows the part
;i:1;s:11:"startModule";s:17:"help_aboutmodules";
inside of the field 'uc'

Now I delete the part
i:1;s:11:"startModule";s:17:"help_aboutmodules";

But it gets restored upon refresh of the page.
s:11:"startModule";s:17:"help_aboutmodules"

How to resolve this issue:

t3lib/class.t3lib_beuserauth.php:

line 128:
// 'startModule' => 'help_aboutmodules',
comment out this line and delete the field uc of the be_users table. Then it works fine in Firefox and Epiphany again.

This error message is obsolete due to the new page tree code in TYPO3 4.2.
