I have a site Im trying to get online right now, and ONLY in firefox this issue happens. In ie9, chrome, and opera it shows perfect. But in firefox when viewing the www.example.com version a block in my drupal site shows about 35px too low. but when going to example.com it will show perfectly as designed as in every other browser.
Now I have used this exact drupal theme on another site on another server. Installing from the same single zip file the theme is from. Yet the original installation works flawlessly. I tried deleting and reinstalling this theme and it did not help. There must be something I am missing. Easy fix is 301 redirect to the non www version but Id rather not cover up the issue. Any help is much appreciated.
