How to backup Firefox profile

Do you use the Firefox browser? It has a nice feature that allow you easy backup all of its data - your complete profile, including bookmarks, passwords, history, installed extensions or themes. All you need to do is copying its profile folders to another location. You can copy them to USB drive and back (e.g. if you reinstall you PC). There are different methods depending on your operating system.

Backup Firefox on Windows 9x/ME

On machines with these old systems, the Firefox profiles can be usually found at this location:

C:\Windows\Application Data\Mozilla\Firefox\Profiles\

Backup Firefox on Windows 2000/XP

If you are using Windows 2000 or Windows XP than go to this folder:

C:\Documents and Settings\<your Windows login user name>\Application Data\Mozilla\Firefox\Profiles\<Profile name>\

Backup Firefox on Windows Vista

Users of the newest operating system from Microsoft should copy this profile folder:

C:\Users\<you Windows login user name>\AppData\Roaming\Mozilla\Firefox\Profiles\<Profile name>\

I strongly recommend backup the Firefox profile folder regularly. Remember, hard disk break down may occur anytime.
