K-Meleon
Note: K-Meleon 1.5.4 looks pretty much like 1.5.3 out of the box. So here's just one shot that goes to show that K-Meleon can be customized to suit various UI wishes.
with Bookmarks & Privacy Bars, no throbber, no URLBar Title.
Some buttons & bars removed, personalized window title.
The Main Menu is shown, popped up on LongClick? on the
Preferences Button (- that is worth trying!)
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.
