Proliferating MIME-type application/octet-stream for PDFs Necessitates mimeTypes.rdf Change

more options

Greetings -

We use a webmail (Squirrelmail) client that a user's webbrowser can connect to to view email. On Fedora Core 7 and Firefox when a mis-MIME-typed (application/octet-stream) PDF file was selected a pop-up box appeared that had options to cancel, save or open the file. With Fedora 11 and Firefox 3.5.3 when I select the same PDF I only get the option to cancel or save.

I attempted to make a change to my mimeTypes.rdf file to give me the option of viewing the file. I used the following webpage ( along with some targeted websearches to come up with the following:


I do get the notice that the application/octet-stream-typed PDF is a 'TonyTest PDF document'. But I still only get the option to cancel or save.

I did find two different extensions that may help: 'Open in Browser' and 'OpenDownload'. But the person I am attempting to help, a man with the first name of 'tenured professor', may still find them a little difficult/confusing/annoying.

I will attempt to train my constituent in using one of the two Firefox extensions. But if possible a cleaner method would be to change a local configuration file (like mimeTypes.rdf) to react to the extension and not the MIME-type.

Darn it. The form gobbled up my mimeTypes.rdf code. Here it is again with the GT and LT symbols replaced with '+':
