pyrates : Xulrunner (Firefox) only fixed their clipboard code to comply with the specification, which is mentionned in the bug description. That only means that Firefox and other applications that rely on xulrunner (thunderbird, sunbird) will have clipboard working correctly, while other applications that still don't implement the specification correctly will continue to have problems. Primary clipboard (middle mouse button) won't stop to work in xulrunner.
