K-Meleon
Note: These screenshots are from the older version 0.8. K-Meleon 0.9 has a new default skin (Phoenity) and better overall user interface. The old, now so-called "Klassic" skin will still be available (Edit - Preferences) and it will include all enhancements through added icons.
These and other skins are located in the Themes and Skins & Throbbers sections.
