Not Reliable Puntuado con 1 de 5 estrellas

Crashed Firefox and did not work to restore passwords and saved cookies. Luckily I also backed up with MozBack and it worked flawlessly.

Did you try a manual restore?

If FEBE fails to restore any item (for whatever reason), you can always restore the backup manually. See and in the FEBE FAQ.
