Firefox 64-bit version for Windows

Veröffentlicht

Hi,

I was wondering how to get a 64-bit version of Firefox, for Windows 7. An Internet search shows these as being available on a couple of website: http://www.windows7download.com/ http://www.firefox64bit.com/

I'm assuming that these are genuine, but I am confused as to why they are not available on the Mozilla website. I searched the support forum and found an answer that is a year old (http://support.mozilla.org/en-US/questions/782154), indicating that a 64-bit version might be available after Firefox 12. Unless I'm confused about the versioning nomenclature being used, the latest version of Firefox is 24. Is there still not an official 64-but version of FIrefox available for Windows?

Thanks & regards, Ashok

Mozilla doesn't have a release version of Firefox 64-bit for Windows operating systems. Mozilla does have Nightly alpha-level 64-bit versions for Windows, but currently they are generated to only verify that Nightly channel changes aren't being broken on 64-bit versions of Windows.

There are a few 3rd party 64-builds available, like Waterfox, but those aren't official Mozilla releases.

Mozilla does not release a 64-bit version of Firefox except for testing. The "Nightly" release is intended only for testers and is not recommended for day-to-day use. I guess not enough advantage has been demonstrated to support a 64-bit release for regular use.

Advantage?

  • I can tell you that the W3C HTML5 single-page spec will not load under a 32-bit browser, or barely will, it's a 14MiB HTML file. I like to be able to do ctrl-f on a document to find things I need. the multipage doesn't allow for that.

that's enough reason for us web designers.

  • plus, 32-bit programs are not as secure as 64-bit from what I read.
  • some of my HTML5 documents may become very similarly large.

you cannot let simple, stupid browsers like IE beat you to the punch. even chrome has a 64 bit browser (not very good, but still better than IE).

I am also busy upgrading my company's web page to HTML5 and need a reliable browser to test these changes on.

Hi Arturius, IE10 and IE11 actually are very sophisticated browsers. But I digress... Personally I do not think a browser needs a 64-bit architecture unless the goal is to enable it to use even more memory than 32-bit architectures allow, and most users who visit here seem to feel that Firefox already uses quite enough memory as it is.

Mozilla has has 64-bit Firefox for Linux and combined 32/64 for Mac OSX ever since Firefox 4.0 released March 22nd, 2011. The Win64 builds however still has some hurdles to overcome for Release.

If I install the64 bit version can I update it each day with the latest Firefox nightly build or will this be an issue seeing as it is a 3rd party version or just a testing version for Mozilla?

Hi maxmaggot, the Nightly release is maintained by Mozilla. Since it contains the latest changes with very little pre-testing, you can expect more problems with stability (more crashes) than the released version.

C++: in windows 64-bit, and depending on your compiler, _WIN64 is defined for 64-bit compiles, and not if it's 32-bit. mingw-w64 can be detected by looking to see if __MINGW32__ is defined. it also #defines the __MINGW64_VERSION_MAJOR and __MINGW64_VERSION_MINOR if you need a compiler version (not sure if this corresponds to gcc version). also, with mingw and mingw-w64, __GNUC__ is defined as with any gcc compiler. hope this helps. I put some of this kind of stuff down here: common c++ #defines
