delete bookmars does not work Rated 5 out of 5 stars
Very good addon, especially for those who use Internet Explorer and Firefox in parallel, as so no additional synchronising tool is needed.
However in the actual combination of PlainOldFavorites 1.1.3 and Firefox 4.0, I registered a small bug:
deleting bookmarks is not working anymore. Actually, I have to delete these manually with the explorer itself.
