Problem with sideboxes in Firefox?

Just about got a new store finished but having a problem with the sideboxes displaying in Firefox. Everything looks fine in IE but when viewing in Firefox the sideboxes are showing in the center (instead of left) and are forcing all other content down below.

A seperate (but maybe related?) issue is a small white space below the header in IE. I read some posts and removed one of the <br class="clearBoth" /> tags in tpl_header.php which removes the space in IE but completely messes up the content area in Firefox and moves everything between the header and footer way too far to the right.

TEST SITE: http://70.85.24.56

I need to launch this site soon so any ideas are helpful!!!

Your "ccaccept" sidebox has an extra </tr> tag near the end of its content. .... somewhere right after your <SCRIPT....> tags for the godaddy SSL seal.

Thanks Dr. - that solved the sidebox centering problem. Now if I can only get the space removed from below the header in IE I'll be good to go!

includes/templates/YOURTEMPLATE/common/tpl_header.php```html

remove this part from that:```html
<br class="clearBoth" />
