On Scroll my web page appears with black background? instead of white; not in chrome or IE
8/3/2014, Dear Sirs,
I own www.aimcmp.com and I am a computer expert of more than 30 years.
On this one page, of my six pages, Computer Help Technical http://www.aimcmp.com/Computer%20Help%20Technical.php
If you scroll to the bottom you can watch the background switch from white to black and again from black to white if you scroll up. This problem is not present with Google Chrome or IE8; therefore you got a serious problem with you browser. Please fix it and notify me when completed. I made screen shots of the problem but see no way to upload them?

On Windows this issue can be caused by the DIV container that is higher than 32000px that causes the background image to stop.
- bug 671302 - cairo-gdi: large background-images and gradients don't work beyond ~ 32735px
- bug 692350 - Table background stops repeating after ~1600 lines

You can try to disable hardware acceleration in Firefox.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need close and restart Firefox after toggling this setting.

Hardware acceleration nor the driver for the graphics card are not a problem. The graphics card has the correct and uptodate driver.
This is not the problem. This is on my own web page. On this web page there is only text and no pictures; therefore no high resolution. It is however a .php page as it has a counter on this page, if that helps? However, I have other .php pages with counter that did not have this problem either. http://www.aimcmp.com/Computer%20Help%20Technical.php
The background is White and should not change, it seem you have a bug, if it can stop? why would it stop? that is a error or bug.
I don't see a problem in Firefox 31/Windows 7 with hardware acceleration disabled in Firefox. I don't have another configuration handy to test at the moment.
You can attach screen shots to a new reply in this thread.
This problem is with Firefox ESR 24.7.0
Here are the screen shots. Some times it is normal and sometimes not. So I have a normal screen shot of my web page; and the error screen shot with the same page with black background showing the error. I have not seen the error recently, so I do not know if it could be a server error maybe with PHP or whether an error with Firefox ESR version before 24.7 as I upgrade after the problem appeared. My web page the error occurred on is: http://www.aimcmp.com/Computer%20Help%20Technical.php the images are less than 500kb none the less they seem not to be uploading; so I made smaller size images.
Does this only happen if you scroll down to the bottom? Does the black background start at a specific position?
What are the default colors?
- Tools > Options > Content : Fonts & Colors > Colors
I've checked the page in an older Firefox 23 version on Linux running under Wine and I can replicate this issue with the background disappearing after about 32500px, so this looks definitely like one of the bugs that I posted above. The DOM Inspector shows a height of 36350px of this table.
I assume that you have a default black color for the background set.

The default color are: text black, and background white. idk why that matters.
Default color set where? In the browser or the web page? The default color in the browser is white for the background. On the web page I would need the name of the attribute to set the background color, I can not find it? Any ways I do not see that any one has a solution?
Firefox is not doing its self any favors by not fixing problem like this, why should there be a limit on column height? Why has Firefox not fixed the video problems, mime type not found, etc. Hello, you making money ... really going to let Chrome over take you?
I get the black background instead of the expected white background after the image runs out.
If I designate white as the transparent color, then I get a white background after the image runs out. It's an improvement, but not a solution.
You can download the modified GIF file here: http://jeffersonscher.com/forumshots/image004_T.gif
OK, can you be more specific how to make your suggested modification? please.
I started with a Microsoft template.
Download the new image and rename it to image004.gif. Then replace your existing image004.gif file the new one.
When you reload the page, bypass the cache by pressing Ctrl+Shift+r to make sure the new image is used.
The expected result is that after the image "runs out," the background is white instead of black.
