Firefox 4 users have two backup options at hand when it comes to creating backups of the web browser (or more precisely their user profile); They can make use of the built-in Firefox Sync to backup passwords, bookmarks, the history and open tabs, or a local backup solution. The latter has the advantage that additional data can be backed up
that is not supported by Firefox Sync. It is for instance not possible to backup extensions and their settings with the current version of Sync.
One of the most popular Firefox backup solutions, MozBackup, has been updated recently in preparation for the Firefox 4 final launch. Previous versions of the backup software are already compatible with Firefox 4, but the developer has improved support in the new version. Mozbackup 1.5 has been released as a beta preview with the promise that the new final version will be released before the Firefox 4 release.
Several issues have been fixed in the beta release, among them backup improvements for profiles with a size of more than 4 Gigabytes. It is unlikely that many Firefox profiles cross the 4 Gigabytes mark, which indicates that this particular change largely benefits users of the email client Thunderbird, considering that all mailboxes and attachments are saved in the profile directory.
How to Backup Firefox with Mozbackup
It takes just a few steps to backup all Firefox data with Mozbackup. I suggest you download the portable version of the backup software from the developer homepage, as it is flexible and can be put on an USB stick.
Mozbackup scans the computer for supported products and displays all that have been found in a list. Portable versions of Firefox and other supported programs, or installations that have not been recognized automatically can be backed up by selecting Portable applications from the menu. It is then necessary to use the folder browser to add profiles from the hard drive to the backup application manually.
The available profiles are displayed in the next step if a recognized installation has been selected.
A click on next opens a prompt with options to password-protect the backup file. It is usually a good idea to add password protection to protect the data from unauthorized access. It would otherwise be possible to access all profile data directly, including saved passwords, bookmarks, the browsing history, extensions and list of downloaded files.
Mozbackup then displays a list of available modules that can be backed up. Everything is selected by default with the possibility to uncheck modules that do not need to included in the backup.
The backup is stored in a single file. You need Mozbackup to restore it at a later point in time.
Firefox users can download portable versions and installers for the latest stable and beta version of Mozbackup directly from the developer website. Mozbackup is only compatible with the Microsoft Windows operating system.
