FF has an extension entitled "Add Bookmark Here 2", found
here.
The main feature IMHO is the ability to add a bookmark without having to open Bookmarks > Add Page > id folder ... etc. Instead, a bookmark can be saved in much the same way that bookmarks are selected to open in a layer or tab, as the case may be. Opera has the same feature built-in, BTW.
Is it possible to add this feature to K-Meleon?
Just wonderin' ...
