FF 7.01 Not Showing Fav Icon Rated 4 out of 5 stars

PlainOldFavorites is great. However, FF 7.01 removes both the Bookmarks and PlainOldFavorites icons from the Navigation bar. Now to access favorites, you need to display the Menu bar continuously or click the orange Firefox menu button and then click Bookmarks or Favorites. A small additional step, but one that was not required before the "new and improved" FF arrived.
Further research... don't know how it happened but the icons were still available; they were simply hidden. After getting an update to FF 7.01, a right click on the Navigation bar and click Customize and I was able to get the icons back.
