If you're using background images or animated background images in tables you cannot read the content of the table. The animated background image is splitted up into a chaos of colourful lines and dots.

Do you got a URL to provide us with an example?
I will do. Unfortunately I deleted the files, because it didn't work. So give me just a little time to create them again. Thanks.
Here's the URL you are waiting for: 1) http://www.it-networks.com/TestGecko/tabletest.html This one should normally show the danish flag (animated) as a table background. All the bright-grey entries in the table should have a black-transparent background-image. In Netscape 4.7 [de] the danish flag is showing properly. Although the speed of the animation is everything but normal. The black-transparent background-color for every entry does not appear. The entries can be red but you have to look at them for the whole animation. In Gecko the danish flag does not appear at all. Every I can see is a colourful image changing every second. The black-transparent background does not appear again. The entries aren't readable. In IE4 and IE5 the table is rendered as it is expected. 2) 1) http://www.it-networks.com/TestGecko/tabletest2.html This one should normally show the danish flag (animated) as a table background. All the red entries in the table do not have any background-image. In Netscape 4.7 [de] the danish flag is separated for every entry. I only have specified a background-image for the outer table. The speed of the animation is everything but normal. The entries can be red but you have to look at them for the whole animation. In Gecko the danish flag does not appear at all. Every I can see is a colourful image changing every second. The black-transparent background does not appear again. The entries aren't readable. (same as in 1) In IE4 and IE5 the table is rendered as it is expected.

I see three "bugs" reported here: - Animated background images in tables do not render at all in Mozilla - Animated background images in tables render incorrectly in Netscape - Animated background images in tables are slow in Netscape That first one could be a valid bug, the second and third one are invalid since they're about Netscape 4.7 and not about Mozilla. However, I'll address each, since the second and third also apply to Mozilla. - Animated background images in tables do not render at all in Mozilla Windows 95, build ID 2000062608 Linux, build ID 2000062808 Both pages showed the flag in Mozilla. I'll see if I can find someone with NT to check this. - Animated background images in tables render incorrectly in Netscape Netscape has a quirk with regard to table background images. They're inherited into each cell, which is what you see in the second example, unless you override them with transparent/other images like you did in the first example. Another trick would be to specify background="" for those cells. IE just renders it into the background of the table, like you saw. Mozilla normally emulates NS4's behaviour... Backward compatibility and such. However, when your page is valid HTML 4 (Strict DTD) and you specify the following as your first line, Mozilla will do the right thing in the second case. (Of course, this breaks support of NS4...): <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> - Animated background images in tables are slow in Netscape Performance under NS4.7, IE5 and Mozilla were comparable, though _slow_ :-( Does anyone know if there's a bug report for this? If not, it should be filed seperately, though I'm not sure if performance can be enhanced much in this case. ------------------------ I did see another oddity in Mozilla though, on both linux and Windows... Between rows 2 /3, 5/6, 8/9, 11/12 and 14/15 there were small gaps. I'll see if I can find a bug report for that.

Marking this bug WORKSFORME. pbotsas@it-networks.com, if you still see the problem of background images on tables not rendering at all in Mozilla in a recent nightly build, please re-open and indicate which build number.

OK, OK. I had to download the newest build which took me quite too long. With Build 2000061311 everything works fine.

I now have Build 20000710.20: On cells 2/3, 5/6, 8/9, 11/12 there is a padding. The table itself has no cellpadding (cellpadding=0). Sorry!

Yes, sorry. The original bug (no background image showing) seems to have been fixed and is why this one was marked "worksforme" (now). The gaps between the rows is dealt with in bug 45055. Marking this resolved worksforme again.
