    Seeing as googling and forum searching brought precious little help, I thought I'd post this to help people with a similar problem in the future.

    Problem: Styles not being applied in Firefox under XHTML 1.0 transitional, but worked with HTML 4.1. An external CSS file that seemed to be ignored. Javascript problems as well. Other browsers fine.

    Cause: Dynamically generated CSS and JS files. Server was reporting MIME type of text/html. HTML page was reporting MIME type of text/css for CSS files. Firefox had been told it was XHTML so was being anal-retentive.

    Fix (for PHP): header('Content-type: text/css'); (or Javascript as appropriate). Remember that header() must be called before ANY html output is sent.

    Based on the fix, the problem you encountered related to PHP generated HTML pages, in the first place? Wouldn't it be considered "good practice" to have PHP send the proper content types along with the HTML content it's generating?
