Globally installing extension, FF6
Trying to globally install an extension. This will be used via Altiris to push out to computer labs so definitely need it working globally, its the NoSquint extension. When trying to add it via seperate folder via registry I tried: HKLM\Software\Wow6432Node\Mozilla\Firefox\Extensions with the key nosquint@urandom.ca with value of c:\program files (x86)\NoSquintAddon. Inside that folder was the xpi of 'nosquint@urandom.ca.xpi. Nothing happens when opening firefox and its not listed on addon tab.
Next tried putting that .xpi inside %installDirectory%\extensions. It shows up in Firefox addon tab but listed as incompatible with firefox 6. I pulled this file directly out of my profile folder after installing this manually.
Is there anything in particular I am doing wrong?
