I'm trying to implement this code, but it's not working. I can get the js to correctly modify the meta tag, but this does not change the stylesheet in the browser. Alternatively I can use the View > Page Syle menu in Firefox correctly. I'm not sure what the problem is.. can you suggest anything? I've tried pasting your code verbatim and that still doesn't work.
