Using FLIR plugin adds strange spacing in page menu in Firefox
 

I'm using the FLIR plugin for some non-standard fonts in my page menu. It renders fine in Opera, Safari and IE but when I have submenus for a menu item, Firefox adds extra spacing into my menu below the menu item. I've tried finding the culprit using Firebug but clearly my CSS skills are lacking. Could anyone take a look at this for me?

Thank you!

looks to me that firefox is not rendering the fones at the same size as I see in safari which would give teh extra blank area below each line of text

Great. Not sure how to fix that. I'll try the forum for the plugin again. Thanks for your help!
