View source for Adding files to an extension's uninstallation

== The uninstall log ==
When an extension is installed, the Extension Manager creates a log of the files which comprise that extension. This log is used by the Extension Manager to cleanly uninstall an extension when requested by the user. Here's a real log created when the [http://passwordmaker.mozdev.org PasswordMaker] extension is installed on a Windows OS:

<pre>
add	C:\Documents and Settings\Fidel Castro\Application Data\Mozilla\Firefox\Profiles\ifk9k760.dev9\extensions\
        {5872365e-67d1-4afd-9480-fd293bebd20d}\install.rdf
add	C:\Documents and Settings\Fidel Castro\Application Data\Mozilla\Firefox\Profiles\ifk9k760.dev9\extensions\
        {5872365e-67d1-4afd-9480-fd293bebd20d}\defaults\passwordmakerdialog.ico
add	C:\Documents and Settings\Fidel Castro\Application Data\Mozilla\Firefox\Profiles\ifk9k760.dev9\extensions\
        {5872365e-67d1-4afd-9480-fd293bebd20d}\defaults\passwordmakerdialog.xpm
add	C:\Documents and Settings\Fidel Castro\Application Data\Mozilla\Firefox\Profiles\ifk9k760.dev9\extensions\
        {5872365e-67d1-4afd-9480-fd293bebd20d}\install.js
add	C:\Documents and Settings\Fidel Castro\Application Data\Mozilla\Firefox\Profiles\ifk9k760.dev9\extensions\
        {5872365e-67d1-4afd-9480-fd293bebd20d}\chrome\passwdmaker.jar
register	profile	package	passwdmaker
register	profile	skin	classic/1.0
</pre>

An extension's log is written to the file <code>%Profile%/extensions/{GUID}/uninstall/Uninstall</code>. Note the lack of an extension on the filename is not a typographical error.

==="Add" entries===
Each <code>add</code> entry in the log contains the full name and path of a file which was written to disk when this extension was installed. In the example above, the <code>add</code> entries have line breaks for clarity, but they are written without these line break in the real log file. The general format of an <code>add</code> entry is:

<pre>
add\tpath\filename\n
</pre>
where <code>\t</code> is a tab character and <code>\n</code> is a newline character.

When an extension is uninstalled, the Extension Manager reads the extension's log and subsequently deletes each file that has an <code>add</code> entry.
