Please kindly check the following pictures.

As the pictures describe...

No matter what is the picture size, it will now display scroll bar...

Does it has any effect if you widen the Firefox window?

This can happen if you make the window that small that all content on visible toolbars isn't fully visible.

Hello, cor-el

Thanks for your reply.

I'm sorry that your providing solution is not working.

Please help to check the new three attached pictures, you can find the window does not show the scroll bar up, the window size is not critical.

I have ask Oracle before, they said this issue will be fixed in the new version of Web Logic Server.

But :

1) In our company , we will not upgrade Web Logic Server to next version this year.

2) If I use MS Internet Explorer(8,9,10,11) to view the XML page, it will not show up the scroll bar, too.

Only Google Chrome and Opera work fine.

So I think this issue will based on browser kernel.

I still appreciate the replying, thank you cor-el.

They may be hiding the scroll bar with CSS code (overflow-y: hidden) or open a pop-up window with hidden scroll bars.

If that is the case then you can override this with site specific code (body {overflow-y: auto !important;}) in userContent.css or use the Stylish extension.

• @-moz-document domain(){}
• @-moz-document url(){}
• @-moz-document url-prefix(){}

You can use the built-in Inspector (right-click "Inspect Element" or via Firefox/Tools > Web Developer) to check for which element you need to make the scroll bar visible if body doesn't work.

The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.

Hello, cor-el

Please kindly read this thread first: https://support.mozilla.org/en-US/questions/976345

I found there are some people have same issues.

I have check the data by source code viewer, the displayed data is 'pure XML'.

So my issue is 'pop-up windows display XML data in Firefox'.

I searched the KB, and found one expert suggest set 'dom.disable_window_open_feature.scrollbars' to 'true'.

This solution solve my problem.

And , thank you again, cor-el.

I can give up google chrome forever.
