Installation directory
The installation directory is the directory where a Mozilla application stores its program files. It is usually a directory on your own computer. This applies to all Mozilla applications: Firefox, Thunderbird, Mozilla Suite, etc.
The installation directory is also known by other terms—program installation directory, application installation directory, program folder, and other similar phrases.
Note: The installation directory is normally separate from your profile folder, which is another place where a Mozilla application stores files.
Finding the installation directory
If you can start a Mozilla application by using a shortcut or launcher icon, then you can usually see where its installation directory is by right-clicking the icon and looking at the properties.
The following sections give examples of the default installation directory for various operating systems and applications, but the actual directory on your system might not be the default. This is because you might have chosen a different installation directory when you installed the application.
If you cannot find the installation directory in either of these ways, then you can try searching your computer's file system. The following sections also give examples of names to search for.
Windows
Examples of default installation directories:
| Firefox | C:\Program Files\Mozilla Firefox\ |
| Thunderbird | C:\Program Files\Mozilla Thunderbird\ |
| Mozilla Suite | C:\Program Files\mozilla.org\Mozilla\ |
| Firefox (Spanish) | C:\Archivos de programa\Mozilla Firefox\ |
Example search for Firefox: firefox.exe
Linux
Examples of default installation directories:
| Firefox | /usr/lib/firefox-<version> For example, if using Firefox 1.0 it would be: /usr/lib/firefox-1.0 |
| Mozilla Suite | /usr/lib/mozilla-<version> For example: /usr/lib/mozilla-1.7.3 |
Example search for Firefox (searching from /): firefox
Mac OS X
Examples of default installation directories (folders):

Note: To open one of these folders, Ctrl-click it and select Show Package Contents. If you simply click it, you will start the application.
