I remember the bookmarks coming in a separate file...IIRC that file was in refhashlist when i was looking into refhashlist...

Try searching in refhashlist with "grob" maybe other than /usr/bin/grob which is the browser you are able to find the file containing the bookmarks...

If i manage to find it I'll report here


Edit: It might be in /usr/share/grob/url_history.db

Fiddle with it and let us know
