Some web-servers intentionally or inadvertently use the
application/octet-stream mime-type for files where either the actual mime-type isn't known or when they are incorrectly configured. Or perhaps where the file is binary and
application/octet-stream is appropriate.
With these mimetypes, the
Open With option is omitted from the file download dialog box.
I would like to modify Firefox mimetype.rdf (or whatever else is needed) to change this behaviour so that "Open With" option is always present.
I have skimmed the Mozilla docs and monkeyed with the rdf a bit, but I am hoping someone has already figured this out.
Of course, if there is an extension I cannot find that just does this already, excellent.
