FireFox =-= Netscape

[xix]

I need some help. Netscape for its bookmarks [ when you had to many] when you saw the bookmarks in Net it would divide it in two panes side by side. Just like you see in windows - start-all programs.
I have so many bookmarks that a single column is silly. I like to have two panes side by side.

Is there a setting in Firefox for this?
or
Do I have to find an add-on? Name???

Thanks.

Firefox has an add-on for 2-pane bookmark panel (like Opera) but I'm with you and would like a side-by-side option.
