[help] What Font Is This?

I am using VS panther 1.5 by KoL. I am not sure what fonts this is on the picture.

Is this Lucida MAC, Macgrande, or other?

I want to change the fonts of firefox bookmarks to this. so ask for everybody.

I'd guess it's plain ol' Lucida Grande, but I'm probably wrong...

ol' Lucida Grande ? Who is 'ol'?

How many kinds of Lucida Grande font? I had one Lucida Grande in my system. and just knew the name of font is Lucida Grande, not knew who is author.

sorry for my bad english!
