Better then Locationbar2 Rated 4 out of 5 stars
makes navigating up or along the path of an address in the address bar very simple. the description is kind of misleading - read the description for Locationbar2, then install this one because it works much better. example of each step possible when navigating up:
http://www.sub.root.com/dir/search?keyword=smart >>> http://www.sub.root.com/dir/search >>> http://www.sub.root.com/dir/ >>> http://www.sub.root.com/ >>> http://www.root.com/
the 3 '...' at the far right of the address bar could be changed IMO, perhaps to an icon.
also i don't understand what the "fission background" option does.
