What does HackerNews think of vimium-c?
A keyboard shortcut browser extension for keyboard-based navigation and tab operations with an advanced omnibar
Note that this extension focuses on searching, not general keyboard navigation. For the latter, you should look into extensions such as Vimium [1], Tridactyl [2], and Surfingkeys [3]. Alternatively, if you are willing to use a niche browser, you should look into Qutebrowser [4], Nyxt [5], and Vieb [6].
I use it with Vimium C [7] and Firenvim [8], which are both excellent browser extensions that focus on more general keyboard navigation. This provides reasonably good keyboard-based web browsing in Chrome/Firefox.
