Firefox Developer Edition additions and improvements

Beyond the new 64-bit capabilities, the Firefox 38 Developer Edition release implements many new features, as it does every 6 weeks when it is updated. Some of these are described below.

Gain faster execution and increased security

64-bit Firefox just goes faster. We get access to new hardware registers and instructions to speed up JavaScript code.

For asm.js code, the increased address space also lets us use hardware memory protection to safely remove bounds checks from asm.js heap accesses. The gains are pretty dramatic: 8%-17% on the asmjs-apps-*-throughput tests as reported on

The larger 64-bit address space also improves the effectiveness of ASLR (address space layout randomization), making it more difficult for web content to exploit the browser.

Review: ***NOTE***
Alex (mralex94) an open-source developer on completely re-compiles and optimizes current Firefox codebase and makes the FAST 64-bit browser available as WATERFOX! Waterfox is compiled with Intel's C++ Compiler with the following optimizations: Intel's Math Library, SSE3, AVX for supported Intel processors, Profile-Guided Optimization and the /O3 switch. Customizations to the base code were also made.

Do NOT be misled! Mozilla Firefox DOES NOT COME IN x64 version...PERIOD. DECISION MADE YEARS AGO BY MOZILLA DEVELOPMENT TEAM AND THEY HAVE NO INTENTION OF CREATING x64 VARIANT! There are a few other projects out there, although I personally use and trust Waterfox x64 and highly recommend it to anyone wanting Mozilla Firefox in truly 64-bit build!
