Firefox "add bookmark" dialog weirdness

[Howard Goldstein]

Under firefox my "add bookmark" dialog is weirded out. When I say 
weirded out I mean it's way too small and not-resizeable, making it 
impossible to add bookmarks through that dialog. Here's a screen capture 
for ex (appx 260K .jpeg)    <http://ecf.queue.to:8080/brokenbkmark.jpeg>

Going through the Organize Bookmarks works fine however and that dialog 
is correctly sized, it only seems to be this dialog (thus far!)

cally:~$ cat .gtkrc-2.0
gtk-icon-theme-name = "Tango"
cally:~$
