Description

[Anders Hasselqvist]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9b5) Gecko/2008032620 Firefox/3.0b5
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9b5) Gecko/2008032620 Firefox/3.0b5

When going to the Swedish page www.idg.se and reading articles the page is often rendered white. By stopping the load before it is completed the page is rendered correctly.

 

Reproducible: Sometimes

Steps to Reproduce:
1. Load the test url
2. Repeat until white out (Seems to depend on the actual advertisement content)
Actual Results:  
Page is displayed (partly) white

Expected Results:  
Content rendered correctly

Using Shockwave Flash 9.0 r115

I can't reproduce this. I even see more than on your "working" screenshot (you're missing the contents of the right hand panel).

Hmm, I have FF2 installed on the same machine and never have the same issue so naturally I assumed it was a problem with FF3...

The reason I am missing content in the "working" screenshot is that I had to stop the loading before all the flash files started playing in FF3. If I didn't do that it was always white. Sorry for the confusion.

Any hints on how to gather information or something I could try to determine the cause of this?

I just disabled all my plugins too see if my suspicion of flash was correct.
However I still experience the same issue.

Some advertisment banners are stilled displayed but are now changed from Flash files to animated GIFs it seems.

I investigated further by installing a WebDeveloper add-on.

I noticed that if I disable on of the CSS files a white page was displayed correctly.

The file is http://www.idg.se/polopoly_fs/2.109!/screen.css.

By editing this file and applying it in runtime I found that changing a css rule made the page displayable:

.vinjett1 SPAN,.vinjett2 SPAN,.vinjett3 SPAN,.vinjettWide SPAN {
	background: Transparent url(/img/idgse/icon_vinjett_arrow.gif) no-repeat
		5px 4px;
	padding-left: 15px;
	text-transform: uppercase;
	font-weight: bold;
	font-family: GillSans, Verdana, sans-serif;
	font-size: 0.92em;
	float: left;
}

If I change or remove the "float: left;" the page is displayed correctly.

I attached the css file in case some one with more knowledge than me about this want to have a look...

Comment 10

I have temporarily fixed my issue by using greasemonkey to override the css rule specified.

I add: ".vinjett1 SPAN,.vinjett2 SPAN,.vinjett3 SPAN,.vinjettWide SPAN {float: right;}"

instead of the "float: left;" in the original script and now I can see the pages, however I have to wait for everything to finish loading first...

I still have the same issue with Firefox 3.1b2. (Greasmonkey not working yet afaik so I get the problem very often)

Anyone has a suggestion how I can narrow down the issue?

The page looks normal here. You could download the latest development build:
http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-mozilla-central/
and start it up with a new profile: http://support.mozilla.com/en-US/kb/Basic+Troubleshooting#Make_a_new_profile

I installed the latest Minefield, created a new profile and started testing.
Still get the same problem.

I also found another page that (as of know) has reproduced the problem every time.
http://www.forum.nokia.com/Resources_and_Information/Tools/

Is there some kind of log I can get from the rendering to see what is happening?

Reporter, are you still seeing this issue with Firefox 3.6.x or later in safe mode? If not, please close. These links can help you in your testing.

I no longer have access to the system where I could reproduce it. But I could reproduce until 2009-07 (not sure what the latest FF version was at the time).
