Waterfox (firefox)

Waterfox was compiled with Intel's C++ Compiler with the following optimisations: Intel's Math Library, SSE3, AVX for supported Intel processors, jemalloc, Profile-Guided Optimisation and the /O3 switch.

Your add-ons/extensions work on any version of Firefox, on any platform! That means they all work with Waterfox. On the other hand, only 64-Bit plugins work with Waterfox and as of now those are: Adobe Flash, Oracle Java and Microsoft Silverlight.

If you find any bugs that you think are related to Waterfox only, report them in the Help section. If you think it's a bug relating to Firefox, then reproduce it on there and file a bug report to Mozilla.
