As you may know, Xombrero is an open-source, lightweight, minimalist, web browser, developed in GTK+3 and based on the Webkit engine. It has been designed for the users that prefer command-line interface over the GUI and has a command mode similar to the one in VIm, for tab switching, entering URLs, following links and navigate through the browser history.

Also, the users can choose the browser’s default search engine.
The latest version available is Xombrero 1.6.4, which has been released a while ago.
Installation instructions:
For Ubuntu 16.04 Xenial Xerus and Ubuntu 15.10 Wily Werewolf, the software is available via some third party PPA, so installing it is easy. All you need to do is add the PPA to your system, update the local repository index and install the xombrero package:
$ sudo add-apt-repository ppa:unit193/xombrero
$ sudo apt-get update
$ sudo apt-get install xombrero
To install Xombrero on Arch Linux, Manjaro, Antergos or another Arch Linux derivative system, install yaourt and install the xombrero package from AUR. Like this:
