Xombrero (formerly known as xxxterm) is an open-source web browser developed with a goal to be a lightweight and secure replacement for full featured browsers like Firefox.[1] The browser has found a niche among minimalist browsers for heavy keyboard users by balancing minimalism with usability.

Xombrero is based on GTK+ 3.[2]

Xombrero is based on the Webkit engine[3] and provides an ability to control cookies, plug-ins and JavaScript policies on per-website basis. The user can define the whitelists of trusted websites for each of those security risks.[4][5]

Xombrero was designed for experienced command-line interface users, so it includes the features typically requested by such an audience: mouseless browsing, no URL prefetch, vi-like user interface and navigation (including command mode), plain text file configuration, and link hinting.[6][7][5]

An ad filtering feature is intentionally absent from Xombrero. The authors recommend using the ad-filtering proxy AdSuck for such purpose.[1]

User interface

Xombrero provides a command mode (designed after vi) for entering commands for the common tasks, including tabs (buffers) switching, entering URLs, following links and navigating through browser history and bookmarks.[3] The same functionality can be accessed with keyboard shortcuts.

By default Xombrero window contains two panels, providing the ordinary layout of a web browser window. The first one (on the top) – "fancy bar" – provides URL entry, backward, forward, stop and white-list toggle buttons and optional search string entry. Another panel (on the bottom) – "status bar" – reports the current URL (or page title), zoom level and position in page. With these panels enabled and a mouse attached, the user may operate Xombrero like Firefox or Midori.


The development of the browser began in February 2010 under the name "xxxterm" by several OpenBSD users specifically for that operating system.[4][8] Initially the releases of the browsers were identified by CVS revision numbers, though more common "X.Y.Z" version numbering scheme was introduced as development moved to Git.[9]

In the release announcement for version 1.11.2, Peereboom revealed the plan to rename xxxterm to Xombrero, though an emergency release under the old name happened later the same day.[10][11] Later it was revealed that the version numbers for the browser under the new name would start again from 1.0.[12]
