I have just had one of those days. You know the type, where everything that can go wrong not only does, but likes to break everything else with it.
What follows are a couple of screenshots from my browser at work. Note I am running a plug-in at the bottom of each window called FireBug which allows you to edit the page live. Anyone who does any decent form of web development will be more than aware of this plug-in and should be using it everyday.
What is it not meant to be able to do is change parts of the browser itself… and thus i present evidence to the contrary.
