Why do borders appear around the frames on a site when the site has no border color set. It does not appear this way in Google Chrome or IE. It only does this with Firefox. How can this be corrected?

Although possibly not related to your problem, I have to remind you that the version of Firefox you are using at the moment has been discontinued and is no longer supported. On top of this, it has known unpatched bugs and security problems. I urge you to update to the latest version of Firefox, for maximum security, stability, performance and usability. You can get it for free, as always, at

As for your issue, hopefully this support article is what you need:

I'm not seeing any borders around the tables that have a border="0" set.
The main table has a border="1" and that is the only table with a border that I see.
Firefox 3.0.19 doesn't show a border either.

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed the maximum file size (1 MB) and do not click Preview after you have attached the image.

Actually I don't have the problem I thought I did.

What seems to be happening is that Firefox (3.6.9) (and every other browser I've checked – Camino 2.0.4, iCab 4, Netscape Navigator 7.2 &, Safari 5.0.2 and Shiira 2.2 – I don't have either Chrome or IE) are using the proper XHTML 1.0 specified behaviour, where the default is frameborder="1" for both frameset and frame.

I'm not sure when this excellent standards-compliance happened (at a guess, if NN7 did it, it would have been the case with Firefox 1.0?) but I never noticed the border in this page before. Now that I've added frameborder="0" attributes for both the frameset and enclosed frames, the border has disappeared.

(Hence, the answer to mts267 is presumably that this is how it's supposed to work unless frameborders are deliberately turned off. Which is a pain, but talk to W3C about that.)

I see the same behaviour still holds when using the ancient nonstandard "border" attribute in place of frameborder, too (which is what we used last time I actually wanted a frame border). Must be my eyesight. :-(

Incidentally, table borders are not the same as frame borders ... I'm talking about frame borders.
