How to back up Firefox's Registry

This post is especially for those who like to mess with their Firefox's registry and fiddling with its settings. You can find some of those settings in the 'Option' tab but not all of them.

So you can do fiddling by typing 'about:config' in the address bar. After you pressed Enter, you'll see a warning message box. The registry of the Firefox is quite powerful yet it's too dangerous to mess with like 'Windows Registry'. That's why it makes you to read the warning message and press "I'll be carefull, I promise!". But still it's quite easy to back it up! You can do it in two methods. I'll show you both methods.

Here is the first method. You don't need to install anything.

Firstly, if you're using Firefox, exit the browser. Then, go to Start → Run (if you're using XP) or pressing Start+R(this will work, too). Type in "%appdata%\Mozilla\Firefox\Profiles" and you will see a folder with the name ending the words ".default". Go inside that folder and find the file named "prefs.js" or "prefs". Then, copy that file to another location or copy to the same location and rename it like "prefs_backup.js" or "prefs_backup". One thing to remember is that you must not move or rename the original file.

Now, you've done backing up your Firefox registry. You can reopen the Firefox and start doing your fiddling. If you messed up with your current setting. You can copy the backup registry file and overwrite the mess-up file. If you copied the backup file in the same directory, you need to delete the current "prefs" file then, rename the backup file as "prefs".

In the second method, you need to install an Firefox extension called "FEBE".
The FEBE extension can backup your bookmarks, themes, preferences, passwords and everything else that Firefox offers. It gathers all the backup in one folder and it also can selectively restore the items you need. The good feature of this extension is the backing up of the add-ons   in the '.xpi' extension so you can flexibly copy and install the extensions between different computers.

So, this is it! Your Firefox settings are safe. You can start changing your setting without worrying of being messed up.
