User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.9) Gecko/20050711 Firefox/1.0.5

The mainframe (named 'mainFrame') is not loaded at all.
<frame src="p/main.html" name="mainFrame">
Infact Firefox sometimes don't send a request. I have tried with and without
cache enabled.
Rather of displaying the content - Firefox displays about:blank.
The same problem occur with version 1.0.4.

Reproducible: Sometimes

Steps to Reproduce:
1. Just load the page.

Actual Results:  
No mainFrame is displayed

Expected Results:  
Displayed the mainframe
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b4) Gecko/20050718 Firefox/1.0+

mainFrame shows up find for me on that page. Could you try this with one of the
latest builds?
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050718

To reproduce this bug do the following.
1. Go to the mainpage (
2. Click on one of the thumbnails at the bottom.
3. Go back to the mainpage (click the logo in the top left corner)
4. Click the same picture again.

Try login with user: test and password: test 
The problem seems to reproduce only when you're logged in. The mainFrame has the
same URL and if you paste the frame URL into the addressbar the frame shows up.
I see this in trunk, too. However, I do not see it with bfcache disabled.

I very much doubt that this is related to bfcache, since Firefox 1.0.x does not
support bfcache. And I see this in Firefox 1.0.3 as well, if I am logged in and
JavaScript is enabled. However, it works for me if JS is disabled.

This leads me to believe that the effect is caused by the following JavaScript
code in the HEAD of the top frame (which is not present when not logged in):


I guess that occasionally the URL of "mainFrame" is still undefined when the
reload is triggered.

Confirming and reassigning to Core/DOM Lvl 0 for further evaluation (I'm not sure
whether this is actually a bug or just some undefined behaviour).

Elmar Ludwig was right. When the script was removed from <head> the page loaded
just fine.
So how do I reproduce the bug?  If the site needs a login, can someone please attach a no-login-required testcase to this bug?
When the bug was reported, it only happened when logged into the site, see my remark in comment 4. The Login/Paswort given in comment 2 still works, but the reporter has since then removed the JS code that caused the problem, so you won't see any problems now...

I will try to reconstruct a minimal testcase today.
Attached file minimal testcase
Testcase (ZIP archive) containing three files. Steps to reproduce:

1. extract files from archive
2. open 301198/index.html

I see the following behaviour (Firefox 1.5rc1 on Linux):

On initial loading, the top frame displays fine, but the lower frame remains empty. "View Frame Info" reports "about:blank" as address, not "main.html".
Reloading the frameset sometimes (but not always) displays the lower frame. Shift-Reload consistently only shows the top frame.

If JS is disabled, both frames load fine.

That's a good question.  What should reload() do for a document that's started a load of a new document but hasn't heard back from the server yet?  Right now we reload the _current_ document.
