MozBackup can also be used to back up and restore Firefox, Mozilla Suite, and Netscape 7 profiles. It works by backing up a Thunderbird profile into a single file (named '*.pcv'), which can then be restored on the same Windows computer or a different one. MozBackup is a standalone utility (for Windows only) rather than a Thunderbird extension. I do hope someone can recommend a step-by-step.This article was originally written for Thunderbird but it also applies to Firefox and Mozilla Suite. Sorry if I haven't been clear enough - am so frazzled and just can't keep stopping all ongoing 'work' to install/uninstall/reboot this 'n that. I started using Thunderbird to replace Outlook Express, so you can imagine there's a heckuva lot of history to be lost but what then? I can't understand how to go about it. I also found a suggested fix - the pcv file should be changed to zip and unzipped, which I've done after copying the pcv into a separate folder. Could I install 1.5.2 beta on top of 1.5.1, or uninstall the latter and install the former? The backed up files are on D-drive, completely separate from program files, and this has always been the case. Then I read that MozBackup 1.5.1 has problems and that 1.5.2 beta is preferable - I've always used 1.5.1.

Somewhere else it said the same thing, almost, but it was registry.dat that should have been created and that's not there either. I've gone round in circles - I saw (paraphrasing) 'after you've installed Thunderbird open it once to make sure profiles.ini is created' but there's no profiles.ini to be found in the x86 folder.

Also, I don't remember seeing this 'default-release' option before.Įventually it went thru the process successfully but when I open Thunderbird this is what I see - I'm sure that in the past Thunderbird opens as it was when I backed it up, not as a new blank program that needs the email a/c setting up :-/ I have used MozBackup for years to restore Thunderbird after a new laptop or a reinstall of Windows, but this time it has failed, over and over.įirst, it couldn't find the pcv but it could when I went into Browse and re-selected the file.
