This is a LIFESAVER!!!
I used MozBU v1.5.1 for years flawlessly to both BU and restore FF. But the last time I tried restoring FF (v37.0.1) from this program it did not succeed in restoring FF. This was in 2015. No error msg's in BU or restore process, so it appears to work, but fails to restore a working FF. I ended up having to restore FF by copy/pasting all Mozilla folders from a BU I had of my entire drive on an external, to my laptop. I notice the version that appears here has been updated as of Dec 2016, however it's the same numerical version I have, so ??? Unless this project has been taken up by someone who has made it compatible with the newest versions of FF, it can no longer be trusted. I am afraid the 4 and 5 star reviews are from people who have not tried to actually restore FF. They just see MozBU seemingly working flawlessly to BU their FF and assume it will restore it when the time comes. If the problems have indeed been addressed and this program is working again, it would be nice for whoever is maintaining it to change it to "v1.6" (or the like) add a note under the download that it has been updated and is working for the latest versions of FF. Otherwise I am said to have to look elsewhere...
Quite a good tool till i used it. had to switch to Mail Backup X since i moved to MAC. the Mail Backup X tool features backing up thunderbird mails in mac as well. it also imported all my mails from the windows i aborted. mozbackup needs to think about mac users as well and mail importing in case pc users ove to mac, the way i did.
