Brave is a free and open-source web browser developed by Brave Software, Inc. based on the Chromium web browser. The browser blocks ads and website trackers. The company has proposed adopting a Get paid to surf business model in a future version of the browser.

Brave created a new “blockchain-based advertising model that reforms the current system with privacy by design and 70 percent revenue share to users in the form of Basic Attention Tokens (BAT)”. Users may opt-in to view ads to earn BAT which they may convert into digital assets and fiat currencies, or use to support their favorite publishers, content creators, and companies.

According to Brave Software, “ad matching happens directly” on user devices which means that data is not sent to anyone.

Basilisk is a free and Open Source XUL-based web browser, featuring the well-known Firefox-style interface and operation. It is based on the Goanna layout and rendering engine (a fork of Gecko) and builds on the Unified XUL Platform (UXP), which in turn is a fork of the Mozilla code base without Servo or Rust.

Basilisk as an application is primarily a vessel for development of the XUL platform it builds upon, and additionally a potential replacement for Firefox to retain the use of Firefox Extensions.

Basilisk is development software. This means that it should be considered more or less “beta” at all times; it may have some bugs and is provided as-is, with potential defects. Like any other Free Software community project, it comes without any warranty or promise of fitness for any particular purpose. That being said: of course we will do our best to provide an as stable and secure browser as possible with every official release of Basilisk.

Chromium是一个由Google主导开发的网页浏览器，以BSD许可证等多重自由版权发行并开放源代码。Chromium的开发可能早自2006年即开始，设计思想基于简单、高速、稳定、安全等理念，在架构上使用了Apple发展出来的WebKit排版引擎、Safari的部份源代码与Firefox的成果，并采用Google独家开发出的V8引擎以提升解译JavaScript的效率，而且设计了“沙盒”、“黑名单”、“无痕浏览”等功能来实现稳定与安全的网页浏览环境。

Chromium是Google为发展自家的浏览器Google Chrome（以下简称Chrome）而开启的计划，所以Chromium相当于Chrome的工程版或称实验版（尽管Chrome自身也有β 版阶段），新功能会率先在Chromium上实现，待验证后才会应用在Chrome上，故Chrome的功能会相对落后但较稳定。

相信很多朋友都正在使用或者曾经使用过Firefox（火狐）浏览器，毕竟对于这么一个具有传奇色彩的软件自然是要尝试一下的。不过一直以来，Firefox有着一个致命的缺点，那就是冷启动速度太慢，有的时候完成第一次启动甚至需要耗费将近1分钟的时间，这么一个看似小的缺陷却已经严重影响了那些首次尝试Firefox的用户热情，一些用户甚至因为无法忍受这一点而转投Chrome阵营。那么如果你也在被这个问题所困扰的话，我们建议你来使用一下“火狐”的同胞兄弟：“苍月”。

所谓“苍月”指的是Pale Moon，是一个基于Firefox浏览器修改优化而来的衍生版本，在Pale Moon项目的官方主页上，项目组人员详细的描述了Pale Moon相比于Firefox原版的修改内容，涉及针对各种处理器的特殊优化，以及对于内部脚本代码的修改和调整，官方表示，Pale Moon修改版相比于原版Firefox，会有25%的速度提升。
