User:Eleanorg/1.2/Forbidden Pixels/Browsable image with CSS & jQuery

This script does all the shizzle with tha image, turning it into a dark html table. You can 'browse' through each cell to reveal each colour: http://pzwart3.wdka.hro.nl/~egreenhalgh/forbiddenPixels/fullGridWithPopups.html
Works fine in Chrome; jQuery only working in my Firefox when firebug console is open. wtf?
