64-bit builds of Firefox were released by Mozilla in conjunction with 32-bit builds for nearly two years for the Windows platform. Mozilla about a month ago announced a change that stopped the creation and development of 64-bit Windows builds of Firefox in favor of concentrating resources on 32-bit builds and other projects.

Where is the 64-bit version of the Firefox web browser for the Windows operating system? That’s a question that I have been asking myself for the past couple of years, probably ever since I updated to a 64-bit version of Windows 7 Professional. Mozilla is offering 64-bit versions of the browser for Mac and Linux, but Windows, the operating system that is used by the majority of Internet users? There have been nightly and custom builds of 64-bit versions of Firefox, but that is about it.

Mozilla Engineering Manager Benjamin Smedberg last Friday quietly posted a thread over on the Google Groups mozilla.dev.planning discussion board titled “Turning off win64 builds.” By Wednesday, Smedberg had declared that the 64-bit version of Firefox for Windows would never see the light of day.

The 64-bit Firefox variant Waterfox 16.0.1 is available, providing Windows users with a stable version of Firefox that’s optimized for 64-bit systems. The latest build finally appears 19 days after Firefox 16 itself released, and includes all the changes and improvements found in the 16.0.1 build of Firefox. However, it has already been effectively made out-of-date by the appearance of Firefox 16.0.2, which contains a critical security fix.

New version! - After watching a video in a Web site, you may want to save the video file into your local disk for playing it offline in the future. If the video file is stored in your browser's cache, this utility can help you to extract the video file from the cache and save it for watching it in the future.

New version! - 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.

New version! - AutoProxy the only fully automatic Proxy Configuration tool. AutoProxy automatically identifies the actual Network location and switches to the corresponding Profile changing the Proxy Settings, Default Printer and Default Home Page.

New version! - LastPass is an evolved Host Proof hosted solution, which avoids the stated weakness of vulnerability to XSS as long as you're using the add-on. LastPass strongly believes in using local encryption, and locally created one way salted hashes to provide you with the best of both worlds for your sensitive information: Complete security, while still providing online accessibility and syncing capabilities.

THE WHISPERED ABOUT Mozilla 64-bit web browser called Waterfox is not a beta, despite appearances, but is a release candidate. Waterfox has progressed in fits and starts and the latest candidate came out earlier this month. However it was incorrectly labeled as a beta release.

Hot on the heels of the slightly delayed official unveiling of Firefox 11 FINAL comes Waterfox 11.0, an optimized build of the Firefox source code for Windows 64-bit users. Waterfox 11.0 contains exactly the same updates as Firefox 11 (see below), plus one major change of its own, a switch from AMD’s Core Math Library (ACML) to the AMD LibM library, which is optimized for 64-bit processors.

Although computers running the 64-bit version of Windows 7 have become more common, there aren't many Windows-compatible browsers compiled to run on 64-bit processors. (The exception for now has been Internet Explorer 9.) - Although computers running the 64-bit version of Windows 7 have become more common, there aren't many Windows-compatible browsers compiled to run on 64-bit processors.

Today’s browsers are constantly trying to improve and beat their competition. This ranges from behind-the-scenes changes to improved speed or standards support, user interface changes for a cleaner look, or even the addition of entirely new features.However, the developers of all those browsers haven’t been very active (or successful) in one type of improvement that could potentially bring some massive results: going from 32-bit to 64-bit.

New version! - The MuvEnum Address Bar saves you time by making it super easy to quickly open files, folders, programs, websites, bookmarks, browsing history, web searches, and more from your Windows taskbar!

Summary: Yes, but …
‘Is there an x64/64-bit version of Firefox?’ I’ve been asked this question a lot lately. So is there an x64/64-bit version of Firefox available. The short answer is yes. Oh, you wanted more. Yes, but …

Earlier this year I wrote about Pale Moon, a version of Mozilla's popular Firefox browser that's optimized for extra speed on Windows. - Besides its focus on speed, another interesting difference in Pale Moon is that it's available in a 64-bit version, where Firefox is not--at least not with an officially supported release.
