Review for Edit Bookmark Plus by Ipitydafoo
Rated 5 out of 5 stars
Exactly what I needed to resolve the issue with Firefox's add bookmark window being unusably small and poorly designed.
Now I can make the add bookmark navigation window as big as I need to.
Drag/re-size tab location is a bit odd, (left corner vs right) but it works.
