# FireFox Bug?

 *  Resolved [msavage123](https://wordpress.org/support/users/msavage123/)
 * (@msavage123)
 * [21 years ago](https://wordpress.org/support/topic/firefox-bug/)
 * I’ve developed a WP 1.5.1 3 column theme at [http://www.greatdealsforthehome.com](http://www.greatdealsforthehome.com)
   and am having problems displaying banner ads between the posts in FireFox only(
   have only tried v1.0.4), IE is fine.
 * When you go to the site for the first time you should notice the first banner
   ad (in the middle column) is displayed too high and the second is also too high.
   In order to avoid flickering of the banners I had to wrap the banner html inside
   a ad-wrap div (padding: 0; margin: 0; height: 65px;) then inside a banner div(
   position: absolute;
    margin: 0px 0px 0px 0px; text-align: center;). The flicking
   stopped after I added this style.
 * Here’s the kicker: when the banners are displayed incorrectly I can resize my
   browser window slightly and FireFox redraws the banners correctly!
 * I’m a CSS newbie so any direction would be appreciated. BTW, I have validated
   my HMTL and CSS and all checks out OK.
 * Thanks.

 * OK I saw this problem within WordPress itself. When editing a post the date and
   time in the Edit Timestamp fields were outside the edit fields! Slightly up and
   to the left. Has anyone else seen this?

 * Got this one figured out. I added an explicit width and height to the post’s 
   img and the ads now display correctly. I spawned off my next site and noticed
   this problem as soon as I added an image to a post. Since I never was able to
   reproduce this in IE I am assuming this to be a Firefox specific deficiency.

 * Your ‘great deals for the home’ site’s markup does not validate. I think your
   ads are importing as HTML rather than XHTML. There may be other issues as well
   with the ads’ formatting, but the main thing is you have to take the outside 
   content into consideration as well as your own, if you want your site to display
   properly in all browsers.
 * Firefox may be deficient, but you can’t prove it by this example.

 * Thanks for the reply. Yes I agree the HTML does not always validate for the ads
   until I go through my “correction” process (I actually wrote a separate page 
   that will display all of my ads so I can validate them – which I apparently need
   to do again). When I was debugging this problem I made sure all of the current
   ads validated.
 * I was able to reproduce the problem with only one ad on another site. It consistently
   displayed the ad incorrectly when I did not explicitly set the img width/height
   and always displayed correctly when I specified the width/height.
 * Then I went back to the [http://www.greatdealsforthehome.com](http://www.greatdealsforthehome.com)
   site and started adding img width/height and the problem went away. I am very
   happy to have figured out the problem especially with the growing popularity 
   of Firefox.
