I use both Mozilla Firefox and Internet Explorer 7. Mainly Firefox and if that particular site couldn’t support Firefox, then Internet Explorer 7 will come in handy. What I really liked about Firefox is it is able to save cookies so that I don’t need to login the next time, username and passwords and even double protect it with Master Password, list of visited websites and also the bookmarks. I know Internet Explorer 7 can do the same but somehow I prefer how Firefox does everything.
Loosing all bookmarks, histories/visited websites, cookies, saved username and passwords from my Firefox browser CAN be disastrous! It happened before, that’s why I always backup my Firefox profile.
I found this tool long ago and have been using it to backup my Mozilla Firefox profiles. It’s very useful and I thought I should share this out to some of you that don’t know about this.
MozBackup is freeware and works on Windows 98/ME/NT/2000/XP/2003. MozBackup is a simple utility for creating backups of Mozilla Firefox, Mozilla Thunderbird, SeaMonkey, Mozilla Suite and Netscape profiles. It allows you to backup and restore bookmarks, mail, contacts, history, extensions, cache etc. It’s probably the easiest way to do Firefox backup!
The zip file is less than 1MB. Simple interface and very easy to use. When you want to backup your Firefox profile, you need to make sure that Firefox is closed and not running. I’ll show you how easy it is to use MozBackup to backup your Firefox profile.
1. You choose whether to backup or restore your profile.

2. After choosing the profile to backup, it’ll prompt you whether you want to password protect your backup file. This is a simple security feature so that no one can steal your backup file and then restore it on their computer.

3. Finally, you select the details that you want to backup. This backup tool is smart enough to detect which details is available for you to backup. Those that is not available, the checkbox would be blurred out.

4. Upon clicking next button, it’ll start backing up all the details you selected. By default, the backup file will be saved on your desktop unless you specify a different location. The backup file extension is .PCV
MozBackup supports backing up these Firefox (Thunderbird) extensions:
* Adblock Plus

* Clippings
* Colorzilla
* Crash Recovery

* File Title

MozBackup backups and restores others extensions too but if these extensions create new files in your user profile with setting, MozBackup doesn’t backups these files. I never backup my extensions. I only have 3 extensions installed that is FlashGot, Google Toolbar and IE Tab. I think that it’s more stable to reinstall the extensions every time I install a new Firefox.
