Rated 4 out of 5 stars
More clear than LittleFox and nearly as compact UI (3/4 compared to Firefox's own UI, while Littlefox is about 2/3).
I wish there would be something that would be between Nautipolis and LittleFox: clear and smooth appearance of Nautipolis and nearly as "compressed" as LittleFox. (SmallFox? NautiFox?)
Shares same flaw as LittleFox regarding RSS-feed in bookmarks: no indication of which pages are visited.
