MOZILLA PROFILES

There is an important concept to understand about all Mozilla-based applications: Where the program is stored, where the User Profile is stored, and that they are stored in different locations.

When you install the program (Firefox, SeaMonkey, Thunderbird, etc.) its files are placed in a standard location, or you can choose "Custom" installation and put the program where you want it. All of the files needed for the program to run are stored in the "program location." The default locations for Windows are:

• C:\Program Files\Mozilla Firefox\
• C:\Program Files\Mozilla Thunderbird\
• C:\Program Files\mozilla.org\SeaMonkey\

You can change the installation location as you like. I recommend only changing the drive and keeping the standard path. For example, on my main system I install all programs to my G: drive's "Program Files" folder. There are a few exceptions where some (very annoying!) programs won't install anywhere except the C: drive. But, as much as possible, I keep my C: drive reserved for the Operating System only.

The second important location to be aware of is the "Profile location." (see below) As noted above, the "profile" is where all of your personal data (account names, passwords, bookmarks, etc.) and settings are kept. As such, it is imperative that you regularly back up the profile(s).

The design logic behind this scheme is simple: It allows you to uninstall and/or upgrade the program without losing or affecting your personal settings and data in any way. When you uninstall/upgrade, for instance, SeaMonkey, it is only the x:\Program Files\mozilla.org\SeaMonkey\ folders and files that are affected, not your Profile files.

PROFILE BACKUP

The simplest approach to backing up a profile is to use whatever utility you use for backing up your other program data. I use BackupMyPC to schedule and perform automated backups of various data on my systems. My server has three hard drives: The main 120 Gb system drive; a 120 Gb drive for video and audio work; and an external USB 160 Gb drive used solely for backups. In addition to backing up various data files I also regularly make an image of the system drive (Windows XP) using PowerQuest Drive Image (now owned by Symantec).

Here's my suggestion on what to back up in the profile:

• Include everything in the base profile folder (the xxxxxxxx.slt folder) and sub-folders structure
• Exclude the cache and cache.trash folders
• Exclude XUL.mfl
• Exclude parent.lock

See PROFILE LOCATIONS IN BRIEF below for basic info. See the following links for more detail on where your profiles are stored and what the different files are.

Note: on Windows 2000 and Windows XP, the Document and Settings directory is hidden twice; to access the directory, you may need to set Windows Explorer to show System and Hidden directories and files. In Windows Explorer click: Tools - Folder Options - View tab. Check "Display the contents of system folders." Under Hidden Files and Folders select the radio button for "Show hidden files and folders." Probably not required but I recommend you uncheck "Hide protected operating system files." Not required but I also suggest unchecking "Hide extensions for known file types." Here is more info

PROFILE LOCATIONS IN BRIEF

SeaMonkey - To quote from the Mozilla FAQ:

• On Windows 95, Windows 98, or Windows ME (without log-in), a typical base profile location is: C:\Windows\Application Data\Mozilla\Profiles\
• On Windows 95, Windows 98 or Windows ME with login, a typical base profile location is: C:\Windows\Profiles\[Log-in Name]\Application Data\Mozilla\Profiles\
• On Windows 2000, XP or Vista, a typical base profile location is: C:\Documents and Settings\[Log-in Name]\Application Data\Mozilla\Profiles\

Firefox - To quote from the Firefox FAQ:

• On Windows XP/2000/Vista, the path is usually %AppData%\Mozilla\Firefox\Profiles\xxxxxxxx.default\, where xxxxxxxx is a random string of 8 characters. Just browse to C:\Documents and Settings\[User Name]\Application Data\Mozilla\Firefox\Profiles\ and the rest should be obvious.
• On Windows 95/98/Me, the path is usually C:\WINDOWS\Application Data\Mozilla\Firefox\Profiles\xxxxxxxx.default\
• On Linux, the path is usually ~/.mozilla/firefox/xxxxxxxx.default/
• On Mac OS X, the path is usually ~/Library/Application Support/Firefox/Profiles/xxxxxxxx.default/

Thunderbird - To quote from the Thunderbird FAQ:

• On Windows 2000/XP/Vista, the path is usually %AppData%\Thunderbird\Profiles\default\xxxxxxxx.slt\, where xxxxxxxx is a random string of 8 characters. Just browse to C:\Documents and Settings\[User Name]\Application Data\Thunderbird\Profiles\ and the rest should be obvious.
• On Windows 95/98/Me, the path is usually C:\WINDOWS\Application Data\Thunderbird\Profiles\default\xxxxxxxx.slt\.
• On Linux, the path is usually ~/.thunderbird/default/xxxxxxxx.slt.
• On MacOS X, the path is usually ~/Library/Thunderbird/Profiles/default/xxxxxxxx.slt.
