Why firefox 64 bit for windows is not available?

Posted

Hello friends. Today, many of computers and cpus are 64 bit. Also most of opeerating systems sucha as windows have 64 bit edition. Now firefox for linux is available. Why mozilla don't publish 64 bit edition of firefox? If the problem is plug-ins availablility, now most of important plug-ins such as Flash player can work on 64 bit browsers. This problem is solving. Other browsers, like Internet Explorer have 64 bit edition. Please work more and more to solve this problem. I posted this on the forum to get notes of other firefox users! Thanks very much.

First, Firefox runs perfectly fine on Windows 64 bit. You can install the 32bit version of Firefox on windows 64 and it works fine (I do it every day and so do millions of users). There is little to no advantage to having a 64 bit browser (IE 64 bit is actually slower than the 32bit) and it doesn't make any real impact for most users.

That being said, eventually there will be a Firefox 64, but right now there is no reason to make it, and there are other higher priorities (reducing memory usage, speeding Javascript up, supporting more HTML5, CSS features, etc.) that are going to have a much bigger impact than x64 support

Thanks for your very good answer. But When we have x64 cpu and x64 os, this means we have more addressing space with more than 3 GB RAM. When firefox supports x64, it can use more addressing space in memory and can speeding up Java Script runs Also in applications such as web based games, and and new HTML 5 web apps). The feature web apps will use more complex code, this codes will run faster on x64 browser. If x64 browser haven't any good reason, why others such as microsoft are releasing x64 browser? and Adboe is suppring x64 in newer flash player plug-in? If x64 IE is slower than 32 bit version, this is because they have little work on 64-bit browser for reducing memory usage and faster runs I think companies must work more and more on supporing maximum capacity of the newer CPUs. After many years past of releasing x64 architecture in hardware world, the the world of software is so retarded. Thanks

Yeah, Firefox needs to be 64-bit.

More and more computers are running 64-bit OS and have 4GB+ RAM.

Firefox 18.0 Can't handle endless scrolling on tumblr. Runs out of memory (limited to 3GB in 32-Bit).

Firefox can't handle tumblr.

Let me start by saying, my previous computer, was a 64 bit, operating with Windows Vista. After numerous problems with Internet Explorer, I finally switched to Firefox, and have used it and loved it for at least the past 2 years.

Fast forward to today. I recently got the HP Envy m6 operating a 64 bit windows 8. Decided to give IE another chance.....that didn't last long, it absolutely SUCKS! So, I figured that i'd download firefox on this new computer. Much better! Unfortunately though, my firefox keeps crashing. It also seems to be running slow in general. Anyone else experiencing this problem?

The crashes seem to occur mostly when running, or attempting to run sites using flash, such as youtube, however I have had crashing on other sites too. Furthermore, I recently installed the adobe plugin, to be able to view pdf files from the net, and anytime I attempt to do that it crashes the browser as well.  :(

VERY unhappy. As far as set up and what not goes, Firefox is the best out there, but under these conditions, I have no choice but to run IE. My best guess is that it's a 32 bit browser running on a 64 bit system. Anyone else having these problems or problems similar that can verify my experience? OR does anyone have any comments or suggestions that may help me get firefox running smoothly on this machine? I miss it!

Firefox crashing is a different story altogether than this thread. Please start your own new thread and provide the crash ID's (type about:crashes into the URL bar and press Enter). With the crash ID we can tell you exactly what the problem is and i can tell you right now it isn't a 32bit browser on a 64bit machine.

I have to tell you that the main reason I used FF was because it was 64 bit. I'm really tired of developers refusing to take advantage of this platform. Kind of like I was about the 640k barrier Windows was so reluctant to break for fear of backward compatibility. I remember having 640k with 8MBs of extended memory. It's time to make the leap now.The people who use FF are not the type to worry about safety, or reliability, as much as they are about speed. If people cared about plug ins they'd be using IE. Explorer 10 now has built in spell check. Even auto correct. FF users want to be on the cutting edge. They are risk takers by definition, and are loyal to you because they feel simpatico. if you restrict them (especially by downgrading their software behind their backs) they will repay your betrayal with more than just the web browser. If Chrome releases a 64 bit version you'll really be sorry you made this 180 in your way of thinking, and became so short sighted. I'm switching already because it's faster, and now only 32 bit. It's very sad, just like Bioware, and Lucas arts, all going console, and AMDs price/value points going above Intels. My favorite brands are letting me down left and right.

hello, firefox for windows has never been a 64bit application - so the premise of your whole statement is not correct.

Circles26 0 solutions 2 answers

Of course it was, and I have the benchmarks to prove it. it uses more memory, and runs at least 10% faster. 32 bit programs cannot access more than 4gb of ram. I only found out that nightly switched me in an "update" because 64 bit flash player told me I was running a 32 bit program. I did discover that they still make waterfox 64bit which is what I'm on right now. Now I feel a little silly, but it would have been nice if they told me about it in the first place. It was not easy to find.

ok, when you are talking about nightly development versions this is a different issue - i was making the statement with firefox release versions in mind.

there are still 64bit versions of nightly produced: ftp://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-mozilla-central/

but using waterfox is probably a better choice in this scenario anyway...

Nearly lost that entirely. I guess it has to wait till Firefox OS is fully developed.

Circles26, Mozilla does not make Waterfox as they are unofficial third-party builds as you can build such Win64 Firefox builds yourself from source. The nighty channel development builds you mentioned (currently at 21.0a1) are not even close to being release builds as they are meant more for developers and testers and not for regular Firefox users. These nighty development builds gets checkins pretty much every day so therefore it gets a update each day with sometimes the odd respin. In fact these win64 nightlies are still more used for to catch breakage then supported like the win32 builds are.

Edit: Also note that occasionally the unstable win64 nightlies gets a check(s) that causes issues, it can take much longer to be fixed or backed out compared to the win32 builds.

Yes, FireFox isn't 64 bit and yes it should be. It isn't because most of the commentators that have technical expertise are technically correct in their analysis. They have limited resources and believe that their resources could be better served by improving the 32 bit version. They are probably right from a development perspective, but they are flat out wrong from a marketing one. This is the inherent problem of open-source lead software development. They can't see the forest through the trees. Anyone with have a brain would know that everything is migrating to 64 bit and if you aren't then you are getting left behind, so of course Firefox should be migrating to 64 bit ASAP. But it won't because the development community is reactive in nature and not proactive. Bottom line, that's why it's a problem and won't be fixed. Firefox will be one of the last applications to go 64 bit. It's unfortunate, but a reality.

Actually it is only on Windows that there is no 64-bit releases as there have been 64-bit versions for Linux and Mac OSX (combined download) ever since Firefox 4.0. The Win64 builds still have a lot of hurdles on different things in getting them to state of being stable for release and lately they were actually downgraded in priority to tier-3 when the official releases are tier-1 supported so it will be a while longer.

This thread is spiraling into a discussion on why Firefox should have 64-bit versions for Windows, which isn't what this forum is for. The answer (There is no Windows-64bit version and no plans for one in the near future) is in the thread. While you may not be happy with that answer, this forum isn't to be used for debates. I'm going to lock this thread, please direct follow up discussions to the firefox-dev newsgroup.
