Most users will find even the thought of backing up firefox or thunderbird profiles daunting. The thought of having to look for the appropriate files or even the appropriate menu and then following a long and tedious task of working through until everything has been found.
Worries incase you have missed anything and are going to loose any important bookmarks or emails fill your head and in the end you decided it might be easier to just keep the system you have.
Well not anymore !
MozBackup is a very simple piece of software which searches your system for the appropriate Mozilla systems (firefox, thunderbird, etc) and then asks what one you want to backup.
All you need to do is click the appropriate one and then the system automatically backs it all up.
PLUS once that is done and your on your new system you can then reinstall Firefox, Thunderbird etc. Reinstall MozBackup and it will restore it all for you again. ITs as simple as pointing to the backup files (i reccommend saving them on a USB stick) and again clicking go.
It really is that simple to backup your Mozilla systems.
The best part is that it is free!!
