I tried Pentadactyl and Vimperator before settling on qutebrowser. It's just fantastic and worth checking out if you're in the market for a keyboard-driven browser.<p><a href="https://www.qutebrowser.org" rel="nofollow">https://www.qutebrowser.org</a>
For another approach to power-tooling your browser, have a look at Gleebox (<a href="http://thegleebox.com/" rel="nofollow">http://thegleebox.com/</a>). I use it constantly to navigate between pages, to get a readable version of the page (!read), and to switch between tabs using a fuzzy-search approach. On some sites I've even added custom jquery-based selectors to quickly navigate around the pagfe.
