Useful? No ... necessary Puntuado con 5 de 5 estrellas

Having up to 4 different firefox instances, scattered between home, laptop, linux and XP, I quickly fell bored of copying bookmarks from one another, having old versions, etc. . . . It is always the first add-on I install and/or recommend to anybody. Superb.
If I may add, it would be unmatched if it did something similar synchronizing add-ons along with bookmarks....
