Firefox background image rendering bug, jQuery
Raw
firefox-fix.js
/*
* I encountered a strange bug with Firefox and dynamic background image updates.
* Background images can't be dynamically updated either through the console or via JavaScript.
* A simple hack is to update the opacity by a very small increment.
* This will force Firefox to re-render the background image correctly.

$(el).css({"background-image":new_image, 'opacity':0.9 + rand_opacity});
