Tracking bug for various content-disposition work: getting up to spec compliance (RFC 2231/5987 encoding), adding properties to channels to hold dispo/filename, and changing the many cases where we seem to be handling the the header in an incorrect manner --> to use the new channel props. We have 187 bugs under 'content-disposition'--I suspect many fall under these issues. https://bugzilla.mozilla.org/buglist.cgi?quicksearch=content-disposition

Bug 224209: content-disposition is not used in tab title. Bug 291837: content-disposition ignored if file is saved with drag and drop. Will those be fixed?

cc-ing Nick, who's in best position to know if those (and the other dependencies hanging off this bug) are easily fixable from the work he recently did.

The two bugs mentioned in comment #1 should be relatively easily fixable when my work in bug 589292 lands, assuming those areas can get to the underlying HTTP Channel (I'm not 100% sure on that from a relatively cursory look at the code). The other bugs depending on this bug may or may not be... bug 272541 will still exist but only in one place instead of multiple places. The rest seem relatively orthogonal to bug 589292.
