Decision leaves Opera and Microsoft with the only 64-bit browsers, though Google will soon join the pack

Fans of the non-profit Mozilla Foundation have waited... and waited... and waited more still, for Mozilla's popular Firefox browser to add 64-bit support.  With pickup of 64-bit SKUs of Microsoft Corp.'s (MSFT) Windows operating system rapidly accelerating, it certainly seemed a 64-bit browser would be just around the corner.

Instead Mozilla has made the curious decision to pull the plug on the long-delayed project, while offering only small clues as to why the decision was made.

The announcement was posted by Mozilla Engineering Manager Benjamin Smedberg on the Bugzilla development page.  He ordered Mozilla employees and community developers:

Please stop building windows 64 builds and tests.

As for why the he opted to pull the plug on 64-bit for now, he comments, "Many plugins are not available in 64-bit versions.  The plugins that are available don’t work correctly in Firefox because we haven’t implemented things like windowproc hooking, which means that hangs are more common."

Mozilla may soon find itself in lonely territory.

With Oracle Corp.'s (ORCL) Java and Adobe Systems Inc.'s (ADBE) Flash now supporting 64-bit Windows plug-ins, both Microsoft's Internet Explorer 10 and Opera Software ASA (OSE:OPERA) have made the leap to 64-bit.  Meanwhile Google Inc.'s (GOOG) Chrome, one of the most popular browsers due to its clean UI and strong GPU acceleration, has added 64-bit support in Linux and is in the process of porting its changes to Windows.

In other words, soon Mozilla may be the only browser maker without a 64-bit browser.

Of course, Windows compatibility libraries ensure 32-bit applications (like Firefox) can still run on 64-bit Windows.  But there is a small performance penalty associated.

For that reason one has to wonder whether Mozilla might come to regret its decision to halt development, even if it is only a temporary one.

No big deal, 64-bit browsers are useless

The big benefit to 64-bit software is normally that they can exceed the 2GB addressing limit present for processes on a 32-bit OS. But this isn't a factor for 32-bit browsers on 64-bit systems for two reasons:

1) 32-bit process on a 64-bit OS can use 4GB of RAM if compiled with the "large address aware" option, giving you double the RAM per process without supporting 64-bit.
2) Modern browsers use a multi-process architecture. Because of this, any one TAB can use up to 4GB, allowing the browser as a whole to far exceed 4GB of RAM

So, on a single-process 32-bit browser on a 32-bit OS, the entire browser was limited to 2GB of RAM usage. Today, a modern 32-bit browser on a 64-bit OS can easily use tens of gigabytes of RAM without ever supporting 64-bit.

That's simply not true.

Native 64-bit apps (on x86_64) have other benefits as well like more registers, better (more efficient) calling convention, faster 64bit math, increased security (due to the larger address space).

Whether all of them are visible / noticeable in a specific app is another question but saying that being able to use more memory is "essentially the only benefit of ANY software compiled for 64-bit operating systems" is plain wrong.

The truth is that performance tests clearly show that unless you are specifically using a 64 bit only feature, or need more then 2 GB of RAM.

What it really comes down to is that all of your memory references have doubled in size. Instead of needing 32 bits to address your object you are using 64. Some would think that this would be a benefit, as 32 bit addresses have to be converted to 64 bit addresses by Windows, but Windows has to convert all memory address, 32 bit or 64 bit. This is because Windows keeps track of memory allocation to prevent programs from accessing or altering other applications and to enable features like paging.

So yes, there are some performance benefits to 64 bit applications, but unless you are using a 64 bit feature extensively the extra cost in RAM and performance is not worth it.

> The truth is that performance tests clearly show that unless you are specifically using a 64 bit only feature, or need more then 2 GB of RAM.

Not sure what you mean by "64bit only feature" but every 64bit application benefits from the additional registers available when running on a x86_64 CPU.

> So yes, there are some performance benefits to 64 bit applications, but unless you are using a 64 bit feature extensively the extra cost in RAM and performance is not worth it.

It is actually the opposite the performance you lose due to the higher memory (and cache) footprint is negible compared to what you gain from the enhancement in the 64bit ISA.

For instance look at:

Most cases where 32bit is faster are in the area of ~5% i.e hardly noticeable in real world apps. While the the test cases where 64bit is faster the performance gain approach up to 50%. That's a huge difference ... its like going from a 3GHz to a 4.5Ghz CPU (assuming linear scaling).

Or another test focusing on linux:

"The performance advantage of 64-bit over 32-bit Ubuntu is clear. If you are still running the 32-bit version on 64-bit capable hardware you should really consider switching"

So unless you are memory constrained (i.e your system is under memory pressure) you are better of running 64bit applications.

In addition to performance you'd benefit from enhanced security as well.

Your support ( is testing 1 version of a program in two operating systems. This would be like running Firefox in Windows 7 x86 and comparing the results to running Firefox in Windows 7 x64. In both cases the application is still 32 bit. The only differences (if any) will be the result of MS coding of 32 bit emulation on the Windows 7 x64 machine, but since they are the same binaries (you are not using the x64 binaries) there should be little noticeable difference.

The problem is that most companies already realize that 64 bit apps are easy (just change the compiler) but actually perform slower then 32 bit apps, so they do not bother releasing the 64 bit versions. This is why all major games which do not hit the RAM limitation do not have a 64 bit version available.

There are a number of situations where having more registers, larger address space, and 64 bit instructions can be advantageous. In these cases the code was rewritten to take better advantage of these features, resulting in modest to large performance benefits. Even so, these are more the exception then the rule.

I think it's better that Mozilla, for now, concentrate on their current 32-bit FireFox browser. I have Win7-64 Pro and 16 GB RAM. I use both IE9 32 bit and FireFox. While I use FireFox for most purposes and I like it better, FF has numerous bugs. Yes, I do like FF better. However, sometimes it can be really irritating. Everyday it seems I come across another bug. Here's one which I just came across tonight. Open this link, then click on the "Basic Essentials, Sterling Denim Jacket" picture on the right side:

You will see that FF does nothing. However, if you drag and drop the link in the picture to any FF tab it will open. Open the same URL above in IE9, do the same thing and you'll see IE9 works correctly.

On your secondary monitor with FF, go to , simply place your cursor over the Corel menu/submenus. You'll see they open to the left side and you can't see the submenus. In IE9, open the same URL in the same secondary monitor and they work correctly. It's irritating to have to switch to IE9 just to see the Corel products in their menu tables.

Also, in the secondary monitor, there is the blank frame problem when Tools > Options > Advanced > Hardware Acceleration is enabled in FireFox.

I have already notified Mozilla about the blank frames problem several times through their Help > Submit Feedback feature but they have not fixed it. They keep updating their S/W. I am currently using FF 16.0.2. Every time I upgrade I hope at least the blank frames problem will be fixed but it's not. FF is now at v17 but I don't expect it to be fixed either.

It appears Mozilla is overloaded with their 32 bit browser so perhaps it's best they concentrate on it and not allocate any resources to a 64 bit browser.

If a page is DESIGNED to run on IE you'll see that. I get the same thing on some MCP sites. I have to use IE to use the pages because MS hates the fact you might come to their site in Firefox etc and so they program their pages to NOT work in anything but their own IE.

It's not firefox's job to be compatible with that site. Write that site and tell them to be compatible with WEB STANDARDS rather than programming purposely to piss off Firefox. You're blaming the wrong people.

Modern browsers use a multi-process architecture.


Because of this, any one TAB can use up to 4GB, allowing the browser as a whole to far exceed 4GB of RAM

Not true, in the case of Firefox.

Firefox only uses a couple of processes (firefox.exe and plugin-container.exe). This has advantages and disadvantages, but that's another discussion. The point is that the main process (firefox.exe) is limited to 2 GB of RAM on a 32 bit OS and to 4 GB of RAM on a 64 bit OS. However, given that Firefox is the most memory efficient browser when dealing with a huge amount of tabs it would take a lot of tabs and add-ons to even reach that limit. My guess is that you'll need about 400 to 500 open tabs to reach 4 GB (I'm running Firefox with dozens of add-ons and have at times over 100 tabs open, I know what I'm talking about)

You're right; it seems like the multi-process migration in Firefox was put on hold about a year ago, much like the 64-bit version was put on hold today.

Well, it still applies to Chrome, and IE, anyhow.

UNLESS you really, REALLY like to use some of the add-ons that have memory leaks.

Right now I have only 11 tabs open in 4 FF windows, with FF using over 400MB of memory. If I keep only this # of tabs open it will eventually climb to roughly 1GB, within a few hours at most.

We can't fault Firefox dev. team for that, but it is a reality that one of the things that makes the browser so great, the add-ons, is also a potential source of high memory utilization.

Can we call this the Adobe memory tax?

By Trisped on 11/24/2012 4:31:17 PM , Rating: 2
I have not found Adobe plugins to leak memory.

Usually this is the result of a free plugin which does not properly clean up after itself.

In any event, if leaving a page open for 1 hour results in the use of more RAM you will probably benefit from finding the plugin which is leaking (Adobe or otherwise) and disable it.

Note: some change in memory usage is normal, like if ads are updated every 15 minutes, or you are watching a video. Simple, static pages should not have these issues, so if you are sitting at Google's home page and the memory usage keeps climbing then you have a problem which should be fixed.

It would seem that your choice of add-ons is rather the question, isn't it.

As of Tuesday when I restarted the computer due to windows updates, I have had an average of over 20 to 30 tabs open at any one time on Firefox Nightly 19.0a1 with about 12 add-ons running. It is using around 500MB right now with 22 tabs open, ranging from heavy flash to plain HTML. So, excuse me if I don't agree with your opinion, I've yet to see a session getting close to what you describe (1GB) in the recent past.

Since I've been running (Minefield) Nightly almost exclusively since the flash support arrived, I had only one instance when it neared the 1GB (890MB with 14 tabs open) mark and it was in the early days of (flaky) 64bit flash development.

The preference of Firefox Nightly usage on a daily basis compared other browsers haven't precluded me from initiating others sessions in IE9 64bit, but it takes me longer to accomplish the same task in it. Chrome becomes wobbly (unresponsive/crashing) with 10 to 12 tabs open and uses more resources than Nightly with twice the amount of tabs open.

But you're not getting my point, that I'd MUCH rather pay money to increase memory in the system than do without the FF add-ons, they are central to my use of that particular system and at this point I'd just stay off the internet before I'd surf what are today sites so obnoxious that it is intolerable without some add-ons and I don't mean only the two most popular nor that it has anything to do with broadband bandwidth, I just despise some of the asshole ideas put out there these days.

Adobe plugins do generally suck, with their closed proprietaryness that nobody but Adobe can fix.

But quite frankly, when today you can buy 16 GB of RAM for under $60, is a few hundred megabytes of utilization really that much of a concern? I agree that code efficiency has plummeted in recent years, but with tens of GB of memory in consumer desktop PC's, I can see how nobody cares.

Firefox is the most memory efficient browser

I'm calling BS on this.

Since you didn't cite your sources and I haven't seen any testing in a little while I went ahead and tested myself.

I'm running Windows 8 x64.
Using the most recent versions of FF, Chrome, Opera, IE10.
12 tabs:
Firefox 214MB
Chrome 89MB
IE 10 320MB
Opera 242MB

32 tabs:
Firefox 381MB
Chrome 93MB
IE 10 722MB
opera 394MB

From this, I would say that Firefox is second most memory efficient when handling a standard user's number of tabs, but would probably settle close to Opera when it comes to a huge (100+) number of tabs.

URL's used for first 12 sites:
The next 24 were the first 24 links from the Wikipedia Article of the Day, up to No. 32 Squadron RAF and including the other references Microsoft Security Essentials , Illinois (album) and Conservation of slow lorises .

No, no BS. But I appreciate that you did you own testing and I accept your results. However, my personal experience tells me otherwise. I find Firefox to use less memory than other browsers (IE, Opera and Chrome) when dealing with 50+ tabs and 50+ add-ons.

I also looked up a few benchmarks to see if independent testing corroborated what I see. Here are the tests I could find:

Toms's Hardware - Web Browser Grand Prix - Memory Usage with 1 tab and 40 tabs ( )
LifeHacker - Browser Speed Tests: Chrome 19, Firefox 13, Internet Explorer 9, and Opera 12 ( )
Ghacks - Chrome uses way more memory than Firefox, Opera or Internet Explorer ( )

As you can see, these independent tests confirm that Firefox is very memory efficient under heavy load.

There is something wrong with your Chrome numbers.

I currently have 9 tabs open (4 Daily Tech, my queue on Hulu, a google search, a Mozilla support page, locations of CiCi's Pizza near me, and a new tab). Chrome's task manager reports:
Tab: DailyTech............32,940K
Tab: DailyTech - .........37,536K
Tab: DailyTech - .........72,888K
Tab: DailyTech - .........33,636K
Tab: queue | Hulu.......71,684K
Tab: Google Search.....18,396K
Tab: Firefox Help.........18,076K
Tab: CiCi Locations......52,880K
Tab: New Tab ............ 12,820K
GPU Process..............120,660K
Plug-in: Shockwave Flash 161,872K

I am using Chrome 23.0.1271.64 m on Windows 7 x64 Pro.
These results are not designed to be a benchmark (which is why the links were not provided) but instead to point out that the previous benchmark seems unreasonable.
It may also be important to note that I am currently using 3.6 GB of 24 GB of RAM. Most applications this would not be an issue, though I have noted a few MS applications (like Office and Visual Studio) try to be intelligent with RAM, resulting in them using more RAM when it is available).
To get these results I took a screen shot since the values keep changing on the DT pages.

It is possible that you are using Windows Task Manager to get your results. If so, then you will need to find all of the Chrome processes since each tab has its own process. Personally I prefer the Task Manager tool built into Chrome, but I have heard some users question its accuracy and truthfulness.

This copy of Firefox 64 bit under Linux has 38 threads running. Several years ago I ran FF 32 bit for plugins and such, but there's no need for that now.

Memory utilization is no big deal. With the 32 bit browser it tended to vary widely and sometimes benefit from a browser restart.

When I saw the headline, it seemed bad until I considered it was Windows only, where it may make sense.

I've used Palemoon for about two years now even on 32-bit machines. Firefox's crappy UI is the main reason. Mozilla failed to bring the Palemoon team on board due to the changes in versioning, and because of massive changes to FF's UI. Palemoon's team wasn't willing to give up on the more "classic" UI to work with Mozzila and I commend them for it.

I prefer Palemoon over Waterfox not only for UI, but because Palemoon is just a better user experience for me.

Now, I have no real clue what Mozzila is saying about a lack of plugin support as flash, Java, Silverlight, and every FF extension I care about works flawlessly... in Palemoon.

Mozilla has released similar statements before about Firefox x64, but this time I think it's safe to assume that we can stick a fork in Firefox and say its development will no longer be moving in a competitive direction. I encourage others to switch to Palemoon and other 64 bit Firefox alternatives and put Mozilla out of your mind like I did almost two years ago.

Mozilla Abandons 64-Bit Firefox Development for Windows for Now

I think the important point in this is the "for now" bit. To me this means that Mozilla plan to release a Windows 64 bit version down the track, which is logical.
I do wonder if the main reason for this is simply economics, i.e. they don't have enough money to develop and maintain a 64 bit version for Windows as well as maintaining a 32 bit browser for the Windows range of operating systems. I would imagine trying to maintain a secure browser for Windows must be quite a challenge, so limiting themselves to just a 32 bit version would simplify matters.
As I understand it, Firefox are continuing 64 bit support for Linux and Mac computers (I've checked and currently my Firefox browser is a 64 bit version).
With Windows XP having an end of life of April 2014, it is only a matter of time before Firefox will stop supporting that operating system, at which time one would expect Firefox to have a 64 bit version for Windows available.

Here is the official Firefox 64bit website:
Notice something odd? It has a section for 64bit Windows operating systems! Sure, its a development site, but Firefox wouldn't bother with doing alphas or betas (or whatever you'd like to call them) unless they did have longterm plans that included a 64 bit browser for Windows 64 bit OSes.
As I said, I think this is more of a hiatus or a time out than an abandonment of the production of a 64 bit browser, and, as I said before, the most logical reasons would be resource related.
To me, because Microsoft has decreed that XP will have an end of life in 2014, then my guess is Firefox are going to put their Windows resources into keeping a secure 32 bit Windows XP compatible version until just after Microsoft close the door on XP, and then they too will close the door on XP.

Last week my boss told me about how slow his old laptop was. his kids couldn't play basic Flash games on it. I thought maybe it was because it was an old machine, but looking around it was fine. It was Vista, but it was fine.

And, opening IE took about 20 seconds for a window to open for that program. So, I installed Chrome. I clicked on IE again... waited a few seconds. Clicked on Chrome... on in a flash. 8 seconds later (I did count), IE came to life.

Now his kids can play the games they want and it's like a new computer, he said. Then he asked me what he could do to keep his wife out of his browser, so I installed FF for him. FF is my main browser, so I know its extensions better than Chrome. It was easy to install a login for Firefox to open.

Anyways, initially I had some major crashing issues with FF, but they seem to be ok now.

FF for the win, btw. Chrome is a close second for me.

That's why I have Opera installed.

I had that same issue on a friend's laptop. Turns out there were about 10-15 pre-installed add-ins for internet explorer. Uninstalling those improved start times and browsing times significantly.

I'm running vista and if IE is running that slow for him, there is some sort of problem with it. Zombie ware or something is running on it.

Actually, Microsoft had 64-bit IE with version 7 when Windows Vista (64-bit) was released.

From my own experience, both Google Maps and Bing Maps are significantly faster in 64-bit IE. But yeah, overall, there isn't much of a difference between 32- and 64-bit web browsers.

There's even a 64-bit version of IE bundled with WinXP x64. It actually worked quite well considering how long ago that was. The reason it wasn't set as default in those days had to do with compatibility with "extras". Flash and Java support for one, and it didn't support 32-bit add-ins, activex controls. Flash and Java both dragged their feet on proper 64-bit support. Nowadays I don't think that's much of an issue, though.

64-bit IE was, at least in the past, quite a lot slower than the 32-bit version, at least in Javascript.

That mostly applied to IE9 IIRC. With IE8 I believe they both used the same javascript engines. IE9 introduced Chakra only on 32-bit. I guess they didn't want to delay it any further, and most users still didn't run the 64-bit version.

However, with IE10 you shouldn't see a repeat of this scenario. Both 32-bit and 64-bit IE10 should be about the same, the 64-bit version might even be a hair better. Also they said that IE10 Metro (since it doesn't run add-ons anyway and uses internal engines only for stuff) defaults to 64-bit. That's good for tablets especially. Desktop IE10 still defaults to 32-bit for compatiblity with add-ons, etc. So there's no loss of function there.

The Firefox codebase is a mess. This is common with open software initiatives and Firefox is no exception. They aren't moving it to 64-bit because, well, they can't, at least without a massive effort. Instead, they'll keep kludging away at the current source (though I still prefer the results to the other browsers.)

If you've spent much time in the commercial software world, you'll be well aware that this is the case for ALL software that's had more and more features added over a period of years.

Perhaps moreso.

If it's closed source, no one can complain about how bad the code is :)

How Windows is still going through these 64-bit teething problems. Like the slow kid, Windows is years behing the rest of the class. UNIX and even Linux had production 64-bit OS's back in the mid 1990's. I know, I used to be a UNIX admin in the late 90's of a farm of DEC Alphas. And Apple OSX went full 64-bit back in 2007.

Like remember when Pentium Pro came out, and all other OS's were fully 32 bit, while Windows was still 16-bit (with a few silly 32 bit extensions). Why is Windows always so far behind the times?

Linux at least you can install all the 32-bit libraries on a 64-bit system, and seamlessly run 32-bit apps, plugins, whatever on a 64-bit OS. OSX is the same, 32 bit apps run seamlessly on 64-bit OS, no tweaking, no dicking around. Why can't Windows do this???

How is FF dumping 64 bit in any way a problem with Windows when every other browsers have 64 bit version?

RE: it's cute
By Argon18 on 11/27/2012 1:36:30 PM , Rating: 2
Because FF is dumping 64 bit Windows specifically because of the technical problems of dealing with 64 bit Windows. It's all in the article.

Addons aren't 64-bit ready because there's no 64-bit to be ready for... you're doing it backwards, Mozilla! You have to take the first steps, not them!

It not system bit mode, we need a new architecture beyond the more then 2 decades old we still stuck on x86 framework.

its not about 32bit or 64bit or even 128bit and beyond. Until the x86 falls way to a new structure, the same issues abound for both hardware and software side of the story.

Difficulty is finding a new system people would use without complaining about backwards compatibility. There is no good NEW architecture available that's none x86, that can support the global x86 world most things run on today. From a business standpoint, its why the x86 still is around for over 2 decades with no close end in sight.

Umm isn't 64 bit Firefox.. Waterox

2014 or 2015 Windows 9 will on the go. Support only 64(may be and 128) bit address extensions. 32 bit does have not support!
