General

Is Windows 7 or Windows 64 bit supported?
Yes.
Where is a Linux or Mac OS X version?
Sorry, no versions for Linux and Mac OS X. I don't have plans for doing these versions.
I don't see version of Firefox/Thunderbird etc. on the list of supported versions. Is my version supported?
Yes. New versions of Firefox/Thunderbird are released every 6 weeks. So it is possible that website isn't updated yet. MozBackup supports all new stable versions of Firefox, Thunderbird etc.
What's *.pcv format?
It's a normal ZIP file. You can rename PCV to ZIP and extract files manually too.
Where backup's file is located?
Default location is folder Documents in Windows profile. You can change this location in program wizard.
Is there a way to make MozBackup work with Portable Firefox?
Yes. Use MozBackup 1.4.8 or higher. In "Profile Selection" you can choose place where you have your portable profile.
Is there a way to make automatic backup?
Yes. Use MozBackup 1.4.8 or higher. Article about automatic backup.
Must I uninstall a previous version of MozBackup before installing a new version?
Yes, it's recommended.
Can I change default backup filename?
Yes. See config file backup.ini in program folder.
Is Lightning extension supported?
Yes.
Can I use MozBackup for synchronization between two PCs?
I don't think this is a good idea. If you use Firefox try Firefox Sync which is better for such task. If you use Thunderbird try to think about having your mails on server and access to them via IMAP protocol. Familiar solution you can have for contacts.

Issues

What can I do if I have a problem with restoration of backup?
Rename PCV file to ZIP and extract manually. Visit MozillaZine KB where you can find how to do it.
After restoration of my mails I don't see some mails in folder. What can I do?
Looks like index file for this folder is corrupted. Try to fix it.
Backup of Thunderbird profile is too big. Any thoughts?
Use "File -> Compact Folders" in Thunderbird before backup. See Knowledge Base on MozillaZine: Compacting folders.
MozBackup detects another version of Mozilla application. How to fix it?
You can ignore this - info about version is only informative. MozBackup gets this information from Windows registry. So if you have old information there, MozBackup shows this. Program backups/restores profiles and for this, it's not important that the version of applications is completely accurate.
After restoration all my extensions are disabled. What can I do?
Close Firefox, go to your profile folder and delete file extensions.rdf.
Cannot open file signons.sqlite. Access is denied.
Some program blocks file signons.sqlite where Mozilla application stores password. Have a look at applications which are running. Find application which blocks this file and close this application.
I got error message "Zip file could not be opened". What's wrong?
This problem is fixed in MozBackup 1.5.
I got error message "resource missing for 11684". What's wrong?
It looks like your hard drive contains bad sectors.
