Rated 4 out of 5 stars
Used FEBE to back EVERYTHING (bookmarks, password, plug-ins, everything). CLEO creaded a nice .xpi file for installation on a different firefox, however, this .xpi does not have all setting FEBE exported.
Please add this to CLEO. With FEBE creating a complete backup, and CLEO creating a .xpi to install later, having the .xpi import literally all settings would rule. Add to that an option to upload the .xpi file to an ftp server of your choice, and the combination would the best backup/restore available (since Xmarks is dieing).
