If you're trying to view a web page and Firefox unexpectedly asks you what you want to do with an .aspx file, it means the server hosting the web site is not properly configured. Only the owners of the web site can fix it.

I suspect that file may not have the correct file extension, if it was "sent" to you.

Typically, when sending a file to a user it makes more sense to use the PDF file format or send the content as an image file.
