Been playing with Sealion Browser lately. It's really cool, very minimal and quick. However, it's based on the same platform as Pale Moon and Basilisk, but the interface is old school Navigator code afaik. https://github.com/wicknix/SeaLion/
Anyway, as a result I discovered the Dorando Keyconfig extension, super cool! Now I can toggle the bookmarks toolbar, the Navigator toolbar, custom bindings for opening/closing tabs, switching tabs etc. Nice! https://addons.palemoon.org/addon/keyconfig/
