I'm not sure what browser I'm going to use to be honest. All the hotkey browsers are buggy as hell since they use qtwebkit, webkitgtk, qt-webengine and whatnot. Chrome has extensions like cvim which sort of work, but they suffer from issues like not being able to properly hook keys and properly notify the user about the state you're in making me frequently make mistakes on what I want to do. As the sibling said a poor imitation of what was possible before.
If firefox just immitates chrome, what's the point in having it? How about trying to eat some of IE's lunch by making enterprise customization a first class citizen? But then again not sure if that matters. And yes I'm aware of GPO, but calling that first class citizen is disingenuous at best.
