This is exactly I was looking for for years!!! I love the Total Commander which is the first Programm I install on a new computer. I've always been unsatisfied with the Firefox Bookmarks managment and thought "Why doesn't it have two panes where I can shove my bookmarks back and forth??? And now, finally ... By the way, somebody's complaining about not being able to "copy bookmarks from one panel to another". It works with some shortcuts. Just take a look at the bottom or in the description. Thanks to Brian for his great work!!!!!
