Ubuntu是一个以桌面应用为主的GNU/Linux操作系统，基于Debian发行版和GNOME桌面环境，与Debian的不同在于它每6个月会发布一个新版本。
普通的桌面应用版可以获得18个月的支持，标为LTS的桌面应用版可以获得更长时间的支持。其桌面应用系列可以获得为期三年的技术支持，服务器版可以获得为期五年的技术支持。Ubuntu的目标在于为一般用户提供一个最新的、同时又相当稳定的主要由自由软件构建而成的操作系统。Ubuntu具有庞大的社区力量，用户可以方便地从社区获得帮助。
这一代最大的特色是全面导入名为Unity的新界面，这也是先前使用在Netbook Remix版本上的界面，相较过去的界面号称更为美观且简单易用。而Ubunty也会针对使用者的显示适配器进行判断，若是安装者的显示适配器性能不足，也会自动改为传统界面，当然看不惯Unity界面，也可以手动选择传统界面。

Waterfox is basically a 64-Bit version of Firefox. The Firefox source code is taken and compiled to run specifically for 64-Bit Windows computers. To make Waterfox stand out a bit more, it’s compiled with optimizations so that it will run more efficiently and faster than just compiling Firefox as a 64-Bit program. For some people with older systems, the 64-Bit version loads quicker and is much more responsive than the 32-Bit build.
In benchmarks, the 64-Bit variant of Firefox out-performs the 32-Bit variant. Also because this variant is being built specifically for Windows, there might be further performance increases. Waterfox was compiled with SSE, SSE2, x64 favoring and the following optimisation flags: /Og /Oi /Ot /Oy /Ob2 /Gs /GF /Gy
Add-Ons work on any version of Firefox, on any platform.
