Mozilla launches 64-bit Firefox Developer Edition for Windows

Mozilla has released Firefox Developer Edition 38, which includes a 64-bit version of its browser for Windows surprisingly, adding to the officially supported Mac OS X and Linux platforms.

The 64-bit version of Firefox brings significant enhancements over the 32-bit version, including the capacity to run bigger applications, speedier execution and expanded security.

"For a portion of the biggest of these applications, a 64-bit browser implies the contrast between whether a game will run," Mozilla says. 4GB isn't as far as possible worth recollecting: Heap sizes, for instance, are prescribed to be 512MB in a 32-bit browser, while they can go up to 2GB in a 64-bit version of Firefox.

With respect to execution time, Mozilla says 64-bit Firefox is faster in light of the fact that it can get to new hardware registers and instructions. This fundamentally accelerates how rapidly JavaScript code can run.

The expanded location space additionally lets Firefox use hardware memory protection and enhances the viability of ASLR (location space layout randomization). The final result implies it is harder for malicious web substance to endeavor the browser.

Here is the full changelog for Firefox Developer Edition 38:

Mozilla propelled Firefox Developer Edition in November, supplanting the Firefox Aurora channel, which sat between the Nightly and Beta channels. Firefox improvement begins with Nightly, which comprises of the most recent Firefox code bundled up consistently for forefront analyzers; Nightly is trailed by Developer, which includes everything that is named as "trial" and went for developers to try out; then Beta is released for more extensive testing. At long last the timetable is capped off with the discharge channel for the more extensive public.

A 64-bit Firefox for Mac OS X and Linux has been accessible for quite a long time, however on Windows the gimmick never made it past the Nightly channel. In November 2012, Mozilla quietly killed off 64-bit Firefox, just to invert the choice after a month after gigantic kickback from clients.

All the more as of late, the organization transformed its tune. With today's 64-bit Developer Edition, we can expect 64-bit builds of Firefox for Windows not long from now.

Here's a game constructed with Epic Games' Unreal Engine running on the Firefox Developer Edition:

Firefox 38 is planned to be launched in May, which would be the soonest a 64-bit Firefox for Windows could be made accessible. It could, obviously, be deferred further. Until it arrives, Windows 64-bit clients can utilize 32-bit Firefox, and both 32-bit and 64-bit versions of Internet Explorer, Chrome, or Opera.
