A while back I posted some code that would create an RSS feed that was compatible with FireFox. This code had to be added to the template index.php page for it to work. Since then I have noticed that in Joomla 1.0.11 in the syndication component you can enable a FireFox specific feed from the syndication component, all the way at the bottom. The added code in the template is not necessary. This can now be controlled from in Joomla instead of hard coding. This way it is easier to change the feed type to some other version of RSS.
