Why dont SVG and MathML-Presentation render in webpages

[squishy]

They will render in my browsers, but only if the URL is directly the source file.

What is the point of such file types if they arent renderable within the content of an HTML webpage?

How do I make them render without sending them to a parser to be converted to a regular image file first? Or by referring to their source file directly in an <iframe tag.

The point of those Markup languages is to server the needs of minority communities. They're really not suitable for general use. However, Firefox should render those pages but you need to properly tell Firefox what's the file type is. Your server needs to be sending a proper mime type with the response header. Can you post a link to one of the troublesome pages?
