All of our GetDirectoryEntries implementations return a nsIDirectoryEnumerator, and a lot of relies on this, and explicitly QIs to it. That gets a bit ugly, and in JS code, a bit expensive. We should just return a directory enumerator directly if that's part of the API contract. MozReview-Commit-ID: IUeEB1Ih1Wu --HG-- extra : rebase_source : 6fffb2d4b0f83db1fd270423a195379acef0dfe4
