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.

Commented Mar 10, 2012 at 10:35@MdGao I found this to be happening on linux - the stupid thing is I no longer access the system that was giving me the problem. Do you have a link I can test against?
