Works OK but does not backup every extension and no styles are backed up.This review is for a previous version of the add-on (7.1.0).
As mentioned in the "About this Add-on" section above, Firefox v20.0 needs FEBE v7.3.0 which is available from the FEBE homepage at http://softwarebychuck.com/febe/febe.html#latest.
