Geocoding not working in Firefox 3.0.6 but works in Safari

Thanks Mark for the extension. I am trying to use this on a project. I can get the map to load in Safari mac, but I can’t get it working in Firefox. I am using EE 1.6.7 and Firefox 3.0.6. When I try to view the page in Firefox, the page loads initially, but then it redirects to a blank page. The error being thrown in Firebug is _mF is not defined [Break on this error] aa("GAddMessages",ma);var oa=_mF[23],pa=...88],bb=_mF[189],cb=_mF[190],db=_mF[191],

Has anyone experienced this error before? I know the thread for this says it has been tested in Firefox, but I can’t get it to work. Any Ideas?
