Stylesheet MIME type incorrectly interpreted as text/html since upgrading to v10
Hi,
I dynamically load a CSS file with some javascript like this:
domStylesheet = document.createElement('link');
domStylesheet.setAttribute('rel', 'stylesheet');
domStylesheet.setAttribute('type', 'text/css');
domStylesheet.setAttribute('href', 'http://my/css/url');
This has always worked until I upgraded to v10 (from v4.6), now I get the error 'The stylesheet http://my/css/url was not loaded because its MIME type, "text/html", is not "text/css"'.

With which content type is the file send by that server if you open the file directly in a tab? Tools > Page Info > General
type shows as text/html. Incidentally, I've tried loading the file in html markup with a <link> tag but get the same error.
Stylesheet files should not be send as text/html, but should be send as text/css
I've already tried changing my apache server config both with a TypesConfig file and explicitly with an AddTypes directive. But, looking at the HTTP headers in LiveHTTPHeaders, the server is sending them as text/html so I suppose the server is at fault. Maybe it always has been sending the wrong type and Firefox 10 no longer allows the type to be overridden on the client side?
Solved it.
Configure Apache to handle .css files with php:
AddHandler application/x-httpd-php .css
Then set the content type with the php header function with this line at the top of the stylesheet file:
<?php header('Content-Type: text/css'); ?>
