It would be useful to use 'content-disposition' and 'filename' parameters to influence FF's handling of such data: URI. Example: Entering this URL in location bar: data:text/html;base64,VGhpcyBpcyBhIHRlc3QK should result in displaying a page with 'This is a test'. Entering: data:text/html;content-disposition=attachment;base64,VGhpcyBpcyBhIHRlc3QK should result in FF downloading a file containing the above content and entering: data:text/html;filename=yay.txt;content-disposition=attachment;base64,VGhpcyBpcyBhIHRlc3QK should result in FF downloading a file called 'yay.txt', containing the above content. Is there any reason not to support at least those two parameters? Libraries like jsPDF would be much more useful with that. Reproducible: Always
Can we please get some assessment and comment about this bug? I'd like to know what are the chances that this is going to be implemented soon-ish.
For anyone who arrives here looking for a solution for the problem, http://www.downloadify.info/ is some sort of solution for that.
I suspect this will be implemented when someone picks it up. See also bug 548516. But exposing the disposition to internal consumers will also need API changes (which I think we've been thinking about anyway; there are existing bugs on it).

This has also been discussed on the w3c mailing list: http://lists.w3.org/Archives/Public/uri/2010Feb/0058.html FWIW, this is not a Mac OS-only issue.
Also, this is not a bug. If we want to extend the data URI syntax, the right way is to write an Internet Draft that updates RFC 2397 and discuss that in the IETF.
I don't think we should extend data: URLs.
