Lightning is a calendar extension for Mozilla CalendarThunderbird available from http://www.mozilla.org/projects/calendar/lightning/. For information on installing Thunderbird extensions see also [[Thunderbird#Silent_installation_of_Thunderbird_extensions]]. ==WPKG Installer== ===Lightning 1.0 Beta 2 for Thunderbird (3.1=== Lightning 1.0 Beta 2 is only compatible with Thunderbird 3.1. Note: -install-global-extension and -install-global-theme have been removed from Thunderbird 3 / Gecko 1.9.2 and upwards. The way to install Lightning as a global)extension is to use xcopy:

<install cmd='cmd /C xcopy /Q /I /E /Y "%PROGRAMFILESSOFTWARE%\Mozilla Thunderbirdthunderbird\thunderbird.exe" extensions\{e2fda1a4-install762b-4020-globalb5ad-extension a41df1933103}" "%PACKAGESPROGRAMFILES%\thunderbird_add-onMozilla Thunderbird\lightningextensions\{e2fda1a4-762b-4020-b5ad-0.3.win32.xpia41df1933103}"' /> <upgrade cmd='cmd /C xcopy /Q /I /E /Y "%PROGRAMFILESSOFTWARE%\Mozilla Thunderbirdthunderbird\thunderbird.exe" extensions\{e2fda1a4-install762b-global4020-extension b5ad-a41df1933103}" "%PACKAGESPROGRAMFILES%\thunderbird_add-onMozilla Thunderbird\lightningextensions\{e2fda1a4-0.3.win32.xpi"' /> <remove cmd='cmd /c echo "How uninstall ONLY add762b-on?4020-b5ad-a41df1933103}"'/></package>

<install cmd='%comspec% /c copy "%SOFTWARE%\Thunderbird\lightning-0.89-tb-win.xpi" %TEMP%' /> <install cmd='"%PROGRAMFILES%\Mozilla Thunderbird\thunderbird.exe" -install-global-extension "%TEMP%\lightning-0.89-tb-win.xpi"' /> <install cmd='%comspec% /c del "%TEMP%lightning-0.89-tb-win.xpi"' />

<upgrade cmd='%comspec% /c copy "%SOFTWARE%\Thunderbird\lightning-0.89-tb-win.xpi" %TEMP%' /> <upgrade cmd='"%PROGRAMFILES%\Mozilla Thunderbird\thunderbird.exe" -install-global-extension "%TEMP%\lightning-0.89-tb-win.xpi"' /> <upgrade cmd='%comspec% /c del "%TEMP%lightning-0.89-tb-win.xpi"' />

<remove cmd='%comspec% /c del /S /Q "%PROGRAMFILES%\Mozilla Thunderbird\extensions\{e2fda1a4-762b-4020-b5ad-a41df1933103}" > nullnul'/>

It looks like to remove an extension Since Firefox 2.0.0.7, the XPI file must reside on a local disk or on a network share (drive letter), it is enough to remove that extensioncan's files t be installed from a UNC path.  ====Don't Import Anything==== The first time Thunderbird is run as a particular user - in including the above caseLocal System account - we get to see the useless "Don't Import Anything" dialog, remove which causes the whole lightning install via "-install-global-extension" to fail. We can work around this as follows: <codesource lang="xml"> <install cmd='%comspec% /c copy "%SOFTWARE%\thunderbird\lightning-0.9-tb-win.xpi" %TEMP%' /> <install timeout="10" cmd='"%PROGRAMFILES%\Mozilla Thunderbird\extensionsthunderbird.exe" -install-global-extension "%TEMP%\{e2fda1a4lightning-762b0.9-4020tb-b5adwin.xpi"' /> <install cmd='ping 127.0.0.1 -a41df1933103}n 10>NUL' /> <install cmd='pskill /accepteula thunderbird.exe' > <exit code="0" /> directory <exit code="-1" /> </install> <install cmd='"%PROGRAMFILES%\Mozilla Thunderbird\thunderbird.exe" -install-global-extension "%TEMP%\lightning-0.9-tb-win.xpi"' /> <install cmd='%comspec% /c del "%TEMP%\lightning-0.9-tb-win.xpi"' /></source> ==Removing an extension==
