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。

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.
