Firefox’s support for feeds via Live Bookmarks is great, but it’s support for the RSS 2.0 spec is wobbly, to say the least. For example, as of now (version 1.0PR), feeds without a link subelement within item will not load, with a message “Live Bookmark feed failed to load” that’s as unhelpful to the user as it is to the feed author who’s trying to figure out what’s going wrong.

This bug makes it impossible to use Firefox to subscribe to heavily-subscribed feeds like, for example, the Scripting News feed. The Firefox community really needs to expand their testcases for this feature if it’s to not look half-assed when 1.0 ships for real.
