Introducing MBackup, a Mozilla profile backup program similar to MozBackup. As of right now, MozBackup is no longer under development. I have reached out to the developer of MozBackup a couple of months ago and received no reply in over six months. Either he’s no longer available, no longer works on the project, or he’s dead and we don’t know it yet.

Whatever the reason, I felt that a new program needed to be made to easily backup and restore Mozilla-type profiles.

This program will backup Seamonkey, Firefox, Thunderbird, IceDragon, Palemoon profiles. It also has support for Google Chrome like profiles as well. The whole concept of the program is to be able to make transporting profiles easy and quick. Select your profile in the list and click Backup. It will then make a compressed ZIP file containing your browser profile and all related files.

Starting with 1.0 Build 4, I have relaxed the requirement for the Microsoft .NET Framework from version 4.5 to 4.0, this makes it so that Windows XP is now supported. Build 3 and earlier required .NET 4.5 because I had not yet found a suitable ZIP compression library and .NET 4.5 had ZIP file compression libraries as part of the framework. I have since found a suitable ZIP compression library (ICSharpCode.SharpZipLib.dll), thus I have been able to relax the requirement back to .NET 4.0.

If you have Build 3 (or earlier) and you update to Build 4, the updating process will download the required ICSharpCode.SharpZipLib.dll DLL file and place it in the same location as that of the program so updating and downloading required program components will be seamless.

System Requirements: Microsoft .NET Framework 4.0
Version: 1.1 Build 5

Version 1.0 Build 7 includes some major fixes to accommodate profile names that have a “.” in them. Before they weren’t being handled properly and would result in the wrong profile being backed up.

    Don’t see the option to backup Thunderbird. Only Firefox, Chrome, Chromium.

      It’s supported Thunderbird from the beginning. Where is your Thunderbird profile located?

        Stumbled upon this page again while clearing bookmarks and replying a bit late on my side. But to answer your question.

        Default install location and was using Windows 7 Ultimate x64. Was going to use this to backup profile before I did a clean install of Windows 10 and the program could not detect Thunderbird for some odd reason. I know the program supported it too. It would only show the previously mentioned programs and never Thunderbird ever. I ended up using MozBackup (even though it was outdated) and restored on Windows 10. To see if the case held true with my Windows 10 installation… happy to report that Mbackup sees Thunderbird this time.

    Many thanks for this little gem.
    Could you please add an option to browse for the profile folder to make a backup of a portable version of for instance firefox.
