Firefox and the case of the missing services menu

So I just noticed something highly disappointing about my new favorite browser: Firefox has zip-ola in the way of integration with the services menu. Am I missing something? Is there a plug-in somewhere that will enable this? Is it a feature that's on the way? My half-hearted Google searches in the middle of 27 other tasks didn't turn up much help, so if anyone has any info, 'twould be appreciated...
