Rated 4 out of 5 stars
FF 5.0--ran from toolbar button with async enabled and alternately disabled and FEBE appeared to perform the same either way--.fbu and .xpi files appeared identical in respective folders. When a full profile backup was selected, runs and displays results page and backup files added to destination directory as expected. Did not try to restore using backup files, but know it worked under earlier versions. When attempted to run a selective backup, FEBE crashed and toolbar button disappeared until FF was restarted. Also tried to run in "Both" mode and FEBE crashed. Seems to only run in full profile mode. Nice full-featured addon--hope Chuck can get wrinkles ironed out.This review is for a previous version of the add-on (7.0.1).
