This is a heads up for anyone having problems with Firefox 3. I had a problem with finding the width()/outerWidth() of elements during a "ready" function, it would always be the size of the window.
While debugging I also noticed a short "FUOC" (Flash Of Unstyled Content), which tipped me off to the possible cause. The solution was to move my CSS stylesheet _above_/_before_ my JavaScript scripts. To make it clearer, I had this: <script src="../scripts/jquery.js"></script> <script src="../scripts/common.js"></script> <link rel="stylesheet" href="../styles/common.css" type="text/css"> And I had to change it to this: <link rel="stylesheet" href="../styles/common.css" type="text/css"> <script src="../scripts/jquery.js"></script> <script src="../scripts/common.js"></script> This is perhaps similar to a problem experienced with an older version of Safari. I haven't gotten round to filing a bug report / looking to see if one's been filed. Karl Rudd
