'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 ...

OK, I'll stop teasing. Yes, there is an x64/64-bit version of Firefox, and it's 100% official code. The 'but' is that it is a nightly build of version 12 (the current official release is version 9) and it's really only suited to testing rather than daily use. Using it will be buggy and plugin support will be close to non-existent.

In other words, unless you are testing, you shouldn't run this. If you are, you can download the nightly build from here.

But there's another option open to you. While Firefox doesn't yet offer an x64/64-bit version of Firefox, because the project is open source, this means that others are free to do just that.

Enter The Pale Moon Project. Here is a project that takes the official Mozilla code for Firefox and builds highly-optimized code both 32-bit and 64-bit Windows systems.

Why run a Pale Moon version of Firefox? Here are the reasons offered by the project:

  • Highly optimized for modern processors
  • 100% Firefox sourced: As safe as the browser that has seen years of development.
  • Uses slightly less memory because of disabled redundant and optional code
  • Significant speed increases for page drawing and script processing (in testing with SunSpider, Kraken and the V8 benchmarks, I'm not seeing these speed increases)
  • Stability: experience fewer browser crashes
  • Support for SVG and Canvas, and downloadable fonts including WOFF
  • Support for HTML5 and WebGL (v4+)
  • Support for Firefox extensions (add-ons), themes and personas
  • Support for OOPP (Out-of-process plugin execution)
  • Able to use existing Firefox bookmarks and settings with this migration tool

There's a 'but' with Pale Moon too ... some features are missing. Specifically accessibility features and parental controls, so if you want these, you're outta luck. Another bump in the road is that if you want add-on support, then bear in mind that 64-bit add-ons and plugins are very rare. For most people, the limited number of plugins is likely to be a big deal-breaker.

So, yes there is an an x64/64-bit version of Firefox, but chances are you're not going to want it.

    I have been using Waterfox for 2 weeks without a hiccup, loads faster than 32 bit Firefox and uses less memory. Plus, my addons still appear to be working.

    There's 64-bit Chrome and MSIE, too. But Chrome rather as Chromium dev project and MSIE as browser you can't set as default.

    3rd party addons and ActiveX are to blame.

    Yes, there has been one for years on Linux.

      @Alan Smithie - Agreed. It has worked just fine for me for like 5 years or so.

      @Alan Smithie Thank you. The title and opening lines of this article had me so confused I just finished checking my package manager to be sure I really had the 64-bit version of Firefox installed that I thought I did before seeing this headline. :-)

    Many of the reasons sited for being a Techie to use Firefox 64-Bit are why I use
    Firefox-4.0b12pre.en-US.win64-x86 64.installer.plugintest.zip and I grab the plug-ins from above this link at: http://wiki.mozilla-x86-64.com/Firefox:Download

    I have found this version to work quite nicely except with places like YouTube. - And of YouTube, I have no use.

    • Your issues are not Firefox related ...

      @The Rifleman YouTube uses Flash and Flash is an issue on anything 64-bits.

        And again I say... Of YouTube I have no use.

      • Kind of Surprised There's No Wrapper

        @wackoae
        In Linux, there is a wrapper for Flash so that you can use the 32 bit version within a 64 bit browser. Often people have used that even when a 64 bit version of Flash for Linux has been available. If 64 bit Flash for Windows is still as buggy as you seem to indicate, I'm surprised nobody has created a similar solution for it.

      Thanks for this tip. I could never understand why Mozilla has been dragging it's feet on windows with this.

    You mean that the Windows version of Firefox is still not 64-bit? I've had this on my Mac since Firefox 4.

  • 64-bit Firefox works just fine.

    I've been using the 64-bit Nightly build of Firefox from https://nightly.mozilla.org/ for at least 6 months with no issues whatsoever. 64-bit Flash and 64-bit Java work fine, which are pretty much all the plugins you need. Plus, there is work on the OOPP side of things where 32-bit Plugins will eventually work with a 64-bit browser.

    Just downloaded waterfox v 10 and like 9 works great. Wish people would do their homework before writing a story.
