Firefox can't display several of my own posted websites, claiming they are already downloaded applications. Other browsers display them.
I've had other people e-mail me and also report that their web browser cannot display images (jpg) on several of the web pages. When I either follow a link to the web pages or enter the correct URL, Firefox reports that it is downloaded an application from the web and asks if it should cancel or open it. If open is chosen, it shows the html text but does not display any of the images. Both Safari and iCab on the Mac displace the entire web pages fine as does the iPad.

That file is send as content type application/octet-stream.
Firefox will never render such a file, but always offer to save a file send with such a MIME type.
See: http://developer.mozilla.org/en/docs/Properly_Configuring_Server_MIME_Types
The html file is labeled as "text/html" in meta data and after downloading "as an application", Firefox still lists the type in page information as "text/html." It is nowhere listed as an "application/octet-stream." Rendering mode is "Standards compliance mode" and encoding is ISO-8859-15. But strangely the Modified date is listed as "30 January, 2010" when the current version of the file is actually 30 October 2010. The actual downloaded file is a version edited and posted earlier today.
What you specify in meta data is not important and is ignored by Firefox. It is the content type in the HTTP response headers that matter and that specifies application/octet-stream.
You can see the response header via the link to the web-sniffer website that I posted above or use the Live HTTP Headers extension.
