Hello Team,

We are not able to see any DHTML banner(expandable flash creative) in Mozilla browser. Kindly let us know why this is not compatible with Mozilla when IE does.

Thanks in advance
Karthick K

Reproducible: Always

Steps to Reproduce:

FYI, when I tried to preview any expandable advertisements in any site thru Mozilla, it shows Back up gif or normal flash. But thru IE, we are getting the expandable banner.

Please do not file normal bugs as security sensitive as it limits the number of people who can view them. 

Please try to file a bug that allows people to reproduce the problem. For example, please include a url to a site that exhibits the problem and give us step by step instructions on how to reproduce the problem. Thanks.

oops, i missed the url. too early on xmas eve. sorry.
BC: It's possible that he wants to protect the URL as private.

Please file in the steps to reproduce, we don't add the fields for fun.
Firefox is like other browser (Opera, safari) mostly compatible with the web-standards (w3c) unlike IE which is less compatible.

To report a bug here you should either compare the results with Safari, Opera and Firefox or look at the html and compare it with the W3C standards. 

I would help in this case with my limited knowledfe but I don't know which dhtml Banner you mean or do you mean a flash banner ?

I will attach a IE screenshot, which part do you mean, there are many not loadable I-Frames.

Attached screen grab for your reference

Matti, you are exactly right. Given URL is the private one which can't be shared. the given URL is the internal test page of world's largest online publisher (63rd rank).

I have attached the screen grab for your reference. If you are not getting the banner, Kindly refresh the page to download the banner.

When we preview the banner in IE, Dhtml Flash creative is expanding properly, but if you try the same URL in Mozilla, you wil get only the Back up gif, which is configured to show to the machine which is not compatible with DHTML Flash.
Hopefully this would be the problem with Ifamre/Javascript coding issue.

So, kindly let me know if mozilla is incompatible with any IFRAME/JAVASCRIPT code then what would be other solution.

once again Thanks all :)

Thanks & regards

Could you possible provide a more minimal testcase? Somehow I doubt this is a problem with Firefox and wading through many pages of source code to find the problem in the html/js code is not especially fun.

First note:
You have many css errors (see tools/error Console) because you use some IE only CSS like this one:
FILTER: progid:DXImageTransform.Microsoft.Gradient

then you use incorrect and broken Browser sniffing :

Never sniff for Firefox, sniff for Gecko.
My UA is for example : Mozilla/5.0 (Windows; U; Windows NT 6.0; rv:1.9.1b3pre) Gecko/20081227 SeaMonkey/2.0a3pre

Just read http://www.geckoisgecko.info/

And the third issue here is that you can't give us such a complex page and tell us that something isn't working.
We do not help with JS/html coding issues in bugzilla and we only want to fix bugs in our products here. That means that we need a minimized testcase. Minimized means that you remove all code that is not needed to reproduce the bug.

You're using IE-only web features, the page is broken in Safari as well. There are lots of places that can help with that kind of problem, but they are not bugs in Firefox.
