Thunderbird Fonts

I have searched for a fix to this but I cant find it... can anyone help me? I have found a perfect font for my system and I have changed both Windowblinds (entire system) and my Firefox fonts... It became really really nice...

However as you can see in the enclosed pic I cant change the two fields in Firefox... Is there anyway to change this? There must be a code to put in userChrome.css that changes these fonts?

All other fonts in Thunderbird has changed through Windowblinds... these two remains.

Please help

That's Lucida Grande, most likely defined in your thunderbird skin.

I kind of figured that... the question is if I can change that font by editing my userchrome.css?
