Enhance bookmarks theme

[mr-cheffy]

What feature would you like to see?

Currently, the bookmarks toolbar that you can pop out uses the default firefox themeing, as shown.

This is functional, but especially when displayed alongside the rest of the browser - as I like to have it on the right with my tabs on the left - it does look misplaced.

Not necessarily as much of a priority, but adding the Zen themeing to the Bookmarks menu would be much appreciated.

Thanks
