Norton Vulnerability Protection - Firefox 22.0

I use Firefox 22.0 RC, however, NAV's install.rdf file contains the below statement, which disables the Vulnerability Protection:

 

    <!-- Firefox -->
    <em:targetApplication>
      <Description>
        <em:id>{ec8030f7-c20a-464f-9b0e-13a3a9e97384}</em:id>
        <!-- firefox -->
        <em:minVersion>3.0</em:minVersion>
        <em:maxVersion>21.*</em:maxVersion>
      </Description>

Once maxVersion is bumpted to 22.* it works okay, but, to do that once a day is a PITA.  Any suggestions (other than to await Fx 22.0's official release)?
