Status: RESOLVED WONTFIX

(Firefox :: Bookmarks & History, enhancement)

Description

[Chris Wood]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.7.8) Gecko/20050516 Waterzebra/1.0.4 (Firefox MOOX M3)

If a feed contains links to other feeds, such links are ignored. Live bookmarks
should be allowed to be nested, and refreshing a live bookmark should refresh
all its child live bookmarks.

Reproducible: Always

Steps to Reproduce:
1. Add http://del.icio.us/rss/gracefool/google as a live bookmark
2. View (refresh) the live bookmark

Actual Results:  
Items in the live bookmark which are themselves feeds (eg.
http://blog.outer-court.com/rss.xml) are not displayed.

Expected Results:  
http://blog.outer-court.com/rss.xml should have been displayed as a live
bookmark inside the live bookmark http://del.icio.us/rss/gracefool/google.

Meh. Even once you avoid an infinite loop, you still face infinite recursion
unless you stop at some arbitrary level, but the real dealbreaker is that links
to feeds just can't be identified. Because of all the practical impossibilities
of identifying feeds in any way other than just fetching the resource and trying
to parse it detailed over and over in bug 255637 (your del.icio.us feed is
served as "application/xml" and Phillip's feed is served as "text/xml"), you
could only do it for Atom feeds that had a <link rel="alternate"
type="application/atom+xml"> or maybe <content type="application/atom+xml"
src="...">, both of which are extremely unlikely to ever be common enough to be
worth supporting, particularly since no other sort of feed reader interface
would actually work to consume them: a feed that worked for Firefox Recursive
Live Bookmarks would just be an annoying muddle in any other reader around.

It would be the sort of cool thing that makes me drag people over so I can point
at the screen and jibber, but it's just not possible in a world where only 10%
of feeds can be identified as feeds in any way other than "fetch, parse, see if
it works."
