64-bit Firefox Developer Edition 38 for Windows
Mozilla is gradually adding support for 64-bit Windows to browsers. Previously, it appeared in Nightly, and at the end of March it is planned to release the first stable release with a 64-bit installer.
As you know, in honor of the 10th anniversary of Firefox in November, a browser version was released specifically for developers - Firefox Developer Edition . It includes experimental development tools (Firefox Tools Adapter b lh /), WebIDE, it has a dark default theme and a separate profile, so the Developer Edition runs in parallel with the usual Firefox.
So, recently a collection of FF versions has been added to the 64-bit Developer Edition under Windows.
As previously reported, the decision to resume the release was made due to the statistics received that 50% of Firefox users on Windows work on the 64-bit version of the operating system. In general, this version was released long ago, since 2010, but was stopped in November 2012.

Unlike Firefox, Microsoft and Google have already released 64-bit versions of browsers under Windows. FF 64-bit versions for Linux and OS X have also been released for a long time, but now Windows users will not feel defective.
64-bit platform gives a number of advantages. Firstly, the 4 GB limit on memory addressing is removed. Increased address space is needed for large applications, like games on the Unreal Engine.

Some of the biggest applications won't run at all in the 32-bit version. For example, when porting to asm.js, it is recommended to set the heap size to no more than 512 MB in a 32-bit browser, but in a 64-bit one you can increase it to 2 gigabytes.
In addition, 64-bit FF just works faster. It is better optimized for modern CPUs and compilers, contains an updated set of instructions and a calling convention that allows more parameters to pass through registers faster. As Google said when releasing 64-bit Chrome, when working with graphics and multimedia materials, there is an increase in productivity by an average of 25%. The stability and security of the browser are also improved, including through the more efficient operation of the ASLR address space randomization mechanism.
In addition to 64 bits, a number of other improvements have been made in Firefox 38 Developer Edition. For example, several media streams are now supported (camera, screen transfer, sound) within a single mozRTCPeerConnection connection, which simplifies the organization of video chat over WebRTC in a browser.
Another useful little thing: a separate filter for XMLHttpRequests in the network monitor and logs in the console.
