Very Handy Rated 4 out of 5 stars

Works great for me on FF 10.0. I use FF's built in bookmarks with FF sync for my personal stuff, and the IE Favorites for work stuff - this way they don't get mixed up with each other, and I don't need to use 2 browsers.

The only thing I'd like to see added is some kind of search/indexing - I can search through FF bookmarks in the address bar, but not the IE favorites.
