Need to add mime type and association

I need to add a new mime_type (application/f4m+xml) and make its handler the mozilla flash plugin. I used to use the mime-edit add-on to do this, but it no longer works. I can add an association for a new extension to an external program, but how do I add an association for the flash plugin?

Re: Need to add mime type and association

Thanks for the help. I shut down firefox, modified mimetype.rdf as shown below, then restarted firefox. Firefox recognized the alwaysAsk setting (it now pops up a dialog box asking "Would you like to save this file?"), but it doesn't ask whether I'd like it associated with plugin. Also, there's a new entry in Edit/Preferences/Applications ("Adobe HDS file"), but the drop-down for "Action" includes only "Save file" and "Use other ...". The latter brings up a file-system browser. Do I need another line in the new mimeTypes.rdf entry that specifies a plug-in? If so, what's the syntax?

Re: Need to add mime type and association

Actually, using the Firefox specific mimeTypes.rdf is not feasible as you can see from the link. You can try to create an XML file for the new MIME type, register it on the system and finally associate it with the desired application as the default. Hopefully Firefox will automatically pick it up at the next startup. Please see this. The xdg-utils tools are usually used for this. Posting in the distribution specific forum would also be helpful.
