[Plugin: NextGEN Gallery] Select Image Button not Working

Hi,

I have Nextgen version 1.9.3 and Firefox 3.6.18. On the Gallery > Add Gallery/Images the Select Files button does not bring up the dialog box to choose files. It does work in IE-9. What do I need to do to make it work in Firefox? I don’t want to upgrade Firefox if possible.

Thanks.
