I am working with the developer of UbuntuZilla to get FF2 to install properly along side the Ubuntu supplied FF3.

His standard is to symlink the FF plugins to where Ubuntu's FF points so the two browsers can sit side by side.

Thus there is a symlink /opt/firefox/plugins that points to /usr/lib/xulrunner-addons/plugins

Not all of the plugins in xulrunner show up in FF2's aboutlugins

Is there such a thing as a FF3 only plugin, thus they will not work with the stable version of FF direct from Mozilla? For example, the nullplugin is in that directory, but it does not show up in

The bug report about this UbuntuZilla is at this URL:
