RequireJS text! plugin and Load timeout

I'm using the text! plugin with RequireJS and Firefox seems to hate my text templates. My code seems to work just fine in Chrome and Safari. Here is the error I get.

Error: Load timeout for modules: text!templates/a.html_unnormalized2,
       text!templates/b.html_unnormalized3,
       text!templates/c.html_unnormalized4,    // _unnormalized# <- What is this?
       ...
       text!templates/n.html,    // I don't see _unnormalized here... why?
       text!templates/o.html,
       text!templates/p.html,
       ...
       http://requirejs.org/docs/errors.html#timeout

First, what does the _unnormalized# mean? It seems to append itself to the file name for some of my templates but not all. However, all of my templates are listed in the error message.

Looking at the Net inspector, it seems to be downloading the necessary template files.
