FireFox 2.0 provides a view of feeds. Compiling Epiphany against firefox 2.0 you are able to view feeds in Epiphany too (see attached screenshot).

This is an interesting and zero-cost feature for Epiphany, but there is an issue: FireFox put an header in feed view, explaing what a feed and providing a button to subscribe to the feed. When you click on button, the FireFox "Subscription Options" dialog appears. This is not good in Epiphany:

 * first the dialog suggest you to use LiveBookmarks, a FireFox only feature, or other web-based feed readers
 * second we have already a RSS feed plugin, able to contact installed feed reader.

My suggestion is:
 1. Keep the feed view in Epiphany. It's a zero cost feature and you have to click over a feed link to open it.
 2. Remove the Subscribe button from the feed view, and use instead RSS plugin if available
 3. Make feed view header translatable in Epiphany, so you don't have to install Firefox language packs
 4. (future) implement something like Safari to "zoom" in timeline :-)
