Is there a plugin in FF to work with Google bookmarks.Chrome (those that are stored in Google.Docs)?

In fact from the topic, everything is clear, I will explain why I use them, not xmarks or Google.Bookmarks (this is another mechanism bookmarks to Google.Toolbar).

With documents saved in the bookmarks, I'm much easier to work with, for example, as I remember them to share. I did that for very convenient wishlist.
