Firefox 3.6+ and Extension Installation Files

Here are the command and xml files listed for use by Firefox#Firefox_3.6_Series_Extension_Templates. The idea comes from [[1] Mozilla Forum Discussion] and the files are adapted from [[2] install_extensions.cmd].

Be sure to 

* put 7zip into packages\mozilla\7-Zip\
* adjust the local path (here: C:\NETINST) if needed
* have the right directory tree

My structure for mozilla installations: 

packages
packages/mozilla/
packages/mozilla/fx_extensions
packages/mozilla/fx_profile
packages/mozilla/tb_extensions
packages/mozilla/7-zip

packages/mozilla/install-extensions.cmd

:: Mozilla extension installation demo script for Firefox and Thunderbird versions
:: based on Gecko 1.9+ from which the -install-global-extension command line option

packages/firefox-ext-skel.xml

Skeleton file for adding new extension by copying "firefox-ext-skel.xml to "firefox-ext-(name).xml". 

<!DOCTYPE firefoxextension [ <!ENTITY ext-name "XX"> <!ENTITY ext-key "XX-00"> <!ENTITY ff-extension SYSTEM "../templates/ff-extension.xml"> ]>
<packages>&ff-extension;</packages>

Change "XX" to name of extension, "XX-00" to extension key of the file.

Example: screengrab-0.96.3-fx.xpi 

* XX    -> screengrab  
* XX-00 -> 0.96.3-fx

packages/firefox36.xml

An additional "firefox check" package is used as dependancy in the extension template, as extensions do not depend from a certain firefox version and therefor need not to be removed when doing a upgrade later to the next firefox generation.

Remarks

There are reported problems (bugs ?) using quoted strings within cmd files. Egfor %zip% . You may have to replace 

set zip="%SOFTWARE%\packages\mozilla\7-Zip\7z.exe"
with 
set zip=%SOFTWARE%\packages\mozilla\7-Zip\7z.exe
in both install-extensions.cmd and remove-extensions.cmd.

For Windows non-specialists, it's possible to hunt bugs/problems redirecting cmd file output to a log file. Replace >NUL in the template file to some >> %SYSTEMDRIVE%\myplace\myfile.txt (for example).
