64-bit Firefox for Windows

I have been getting OOM crashes with increasing frequency since the FF versions went into the high 20s.
Here are two recent examples:
bp-83e13b3c-d74f-457d-b85d-1b73d2140624
bp-26ecae7c-6318-4f6a-baaa-e47062140623
and one not so recent:
bp-8d49562a-07b8-451a-b65e-8f80a2140410
I would expect OOM problems are directly related to limitations of the memory model of a 32-bit process.
Please promote the nightly 64-bit builds to a supported platform.
For an argument why making 64-bit Firefox officially supported makes technical sense please have a look at Peter Bright's article:
http://arstechnica.com/information-technology/2012/11/64-bit-firefox-for-windows-should-be-prioritized-not-suspended/

jscher2000: yes, the virtual size of my firefox.exe process typically hovers around 3.1-3.3GB. This and the frequency of crashes (60 on this computer this year, predominantly OOM) leads me to believe I am coming up to limits of the 32-bit build.
John99: in my case safe mode approximately halves the VM size of the process so it moves it away from the 32-bit "danger zone"; however, while I am happy to disable all add-ons for a one-off test, I would not do that for my day-to-day use.
Yes, switching add-ons off and keeping a smaller number of tabs and windows open would reduce memory pressure - but these are workarounds, not solutions. If IE and Chrome can keep up with my browsing patterns, shouldn't Firefox also be able to?

How can install the Fractal Image plug-in into Firefox for Windows 7?

I have the plug-in necessary to view fractal images built with the now no longer Iterated Systems program "Fractal Imager." These are files with the .fif extension and the plug-in is needed to view them. The plug in I have is fully functional. The problem I am having is that I needed instructions on how to upload this plug-in into Firefox for Windows.

There has been a change in where Firefox searches for plugins and the plugins folder in the Firefox program folder is no longer scanned for plugins, so Firefox won't find them anymore if they are installed in the plugins folder instead of the "browser\plugins" folder that Firefox now scans.
You can set the plugins.load_appdir_plugins pref to true on the about:config page to make Firefox scan the "<install>/plugins/" directory for plugins like the WMP plugin (np-mswmp.dll).
You can alternatively move plugins from "<install directory>\plugins\" to "<install directory>\browser\plugins\" (create this folder when missing) to make Firefox find them again.

I cannot even get it to load my music files without freezing and I have to close and reopen and start over. I have used previous versions on other computers with no problems. Any suggestions? Thank you.

64-bit Editions for Windows XP

Yeah I see a lot of post and questions about 64 bit edition for Windows Vista... but is there a 64 bit edition for Windows XP of iTunes or does the vista version work with the 64 bit edition of Windows XP? Cause everytime I try to download the iTunes on the main page it says It calls for 64-bit edition and that I need to go download that version... is there a version of Itunes for Windows XP 64-bit?

I am a Mac advocate but have to use Windows and currently uses Windows XP Pro 64Bit (SP2) and I have the same issue I have found several websites on how to work around iTunes's problem to get it to work but what I am looking for is a way to request Apple to include the 64-Bit drivers and modify the install to recongize Windows XP Pro 64-Bit as a valid OS. This is all the work arounds are doing in the first place. I DON'T want to got Vista x64 to get a supported configuration of iTunes. You have 64-bit drivers for bootcamp so ITunes and Safari should be 64-bit.
BTW Here is the site I found with the workaround
http://yukichigai.googlepages.com/iphonex64
Steve love your products but we need your apps to work in 64-bit on XP Pro 64bit and Vista 64bit, don't do a Microsoft.
Also while your at it can you hurry u with the Blue-Ray capable 15' MacBook Pros that can do WUXGA or 1080p HD resolutions (1900x1200).
Thanks for the lack of blue screens,

64-bit version for windows not working

ive installed the 64-bit version for windows, i connect my 5s and it tells me to uninstall itunes and reinstall the 64-bit because the itunes isnt the right version

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

F3507g 64 bit drivers for Windows 7 RTM - where can i find them.

Does any one know where i can find the 64 bit drivers for Windows 7 RTM for the F3507g
thanks in advance.

The reason that threadjacking is frowned on (as mentioned in the terms use which you can read by clicking the link to the right on this page) is for the most part a practical one:
By starting your own thread your problem can get individual attention, focussed on your particular set of circumstances.
By joining somebody else's older thread it becomes tricky to answer more than one question at the same time, and can lead to confusion for both parties.
So if you don't mind the minor inconvenience, please start your own thread (in the correct forum) so we can get to grips with your particular problem. Please include details of your computer and operating system.

Where can I down load older versions of FireFox for windows and Mac for testing my application? I need to have copies of version 3, 4 and 5.

My tesm develops .net applications that must support many browsers and we need access to download older versions of FireFox for windows and mac computers, so that we can test our application prior to rolling out a new version.
Where can I download older versions of FireFox

Firefox 3.5 is an antique version that is chock-full of security vulnerabilities. 
Firefox 3.6 also contains security vulnerabilities; it stopped being supported on April 24.
* [https://www.mozilla.org/security/known-vulnerabilities/ www.mozilla.org/security/known-vulnerabilities/]
If you can't run the latest version because your system doesn't meet the requirements, it's highly recommended that you use another browser that is secure. TenFourFox is a third-party build of Firefox that is kept up-to-date and runs on Mac OS X 10.4 and PowerPC Macs (as a side note, I've never seen the site go down; whatever problems James noticed 9 months ago must've been a fluke).
* [http://www.floodgap.com/software/tenfourfox/ www.floodgap.com/software/tenfourfox/]
If your system can run the latest version, but you want to downgrade because you've experienced problems, please start a new thread and someone will try to help you.
If you understand the security risks but want to downgrade anyway,
* Firefox 3.6: [http://www.mozilla.com/firefox/all-older.html www.mozilla.com/firefox/all-older.html]
* Firefox 3.5: [ftp://archive.mozilla.org/pub/mozilla.org/firefox/releases/3.5.19/ ftp://archive.mozilla.org/pub/mozilla.org/firefox/releases/3.5.19/]

When I downloaded Firefox for windows, the security scan wouldnt allow it. I operate on windows 7 and was downloading mozzila firefox8

Hi annarepublic78,
As per the above mentioned error, your Win CS6 download was not complete, either it was in process or was interrupted. This is the only reason you see the MasterCollection_CS6_LS16.7z.crdownload. Here .crdownload means the download is in process.
Please try to download it again on the Desktop and please make sure that the download completes successfully(without the .crdownload extension).

Does Firefox 7.o have a supported 64-bit version for Windows 7?

On the system requirements page for Firefox 7.0, I found the following statement: "Please note that while the 32-bit and 64-bit versions of Windows Vista and Windows 7 can be used to run Firefox 6, only 32-bit builds of Firefox 6 are supported. at this time."
I do not understand why Firefox 6 is mentioned on the Firefox 7 system requirements page. I have Windows 7, 64 bit version.
Does Firefox 7.0 have a supported 64 bit version that runs on Windows 7--64 bit version?

Not yet. The web page text is incorrect.

Is there a nightly 64-bit version of firefox for windows?

I know that you cannot compile a official stable version of 64 bit Windows because you mistakenly think it's enough with the unefficient 32bit version. But what I want to ask you is if there is a nightly version of 64 bit for windows, and if it exists, where can I get it, Zipped or installer (please, I would like binaries; I don't want to fight for hours with many configuration files, compiling process and so on).
PD: Please release a 64 bit version of firefox on Windows. What more do you want to postpone it?
I saw a st*pid answer like «Yep :) Firefox works fine on both 32bit and 64 bit, so no need to worry :) », but this is NOT a solution. I have a 64bit OS, then, I would like to use full advantages and performance of this more modern platform rather than a less capable version. I dont have many GB of RAM and a multicore CPU as a decoration.

Win64 Nightly has existed for some time however they are not supported (like the Win32, Mac OSX 32/64-bit and Linux 32/64-bit are) as they are currently more for to catch breakage/regressions. https://developer.mozilla.org/en-US/docs/Supported_build_configurations
No it is not simply because the 32-bit version works.
The 64-bit Windows builds has still been a work in progress on a number of things that needs to be in order, especially for Win64 Releases to happen.

How to delete firefox for windows?

program uninstall does not work

Now, uninstall Firefox by following the steps mentioned in the [[Uninstall Firefox from your computer#w_uninstall-firefox|Uninstall Firefox]] article.
'''IMPORTANT:''' On Windows, the uninstaller has the option to remove your personal data and settings. Make sure that you do '''not''' check this option; otherwise all of your bookmarks, passwords, extensions, user customizations and other Firefox [[Profiles|user profile data]] will be removed from your computer.
After uninstalling Firefox on Windows, delete the "Mozilla Firefox" program folder, located by default in one of these locations:
* '''(On 32-bit Windows)''' ''C:\Program Files\Mozilla Firefox''
* '''(On 64-bit Windows)''' ''C:\Program Files (x86)\Mozilla Firefox''
#Go to the Windows Start menu and click on "Computer".
#In the Explorer window that opens, double click Local Disk (C:) to open the C:\ drive.
#Find the "Program Files (x86)" folder or "Program Files" folder.
#* On 32-bit Windows, double-click the '''Program Files''' folder to open it.
#* On 64-bit Windows, you will see a "Program Files (x86)" folder AND a "Program Files" folder. Open the '''Program Files (x86)''' folder.
#Look for a '''Mozilla Firefox''' folder. If you find one, right-click it and select ''Delete'' and confirm that you want to move the folder to the Recycle Bin.
Now, go ahead and reinstall Firefox:
#Double-click the downloaded installation file and go through the steps of the installation wizard.
#Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

I need to download 32 bit Firefox for chemdraw(application), but can only install 64 bit. Is there any way to manually download 32 bit Firefox?

Hello, I am currently using Connect.com as a chemistry supplement, but cannot answer some questions because its ChemDraw application cannot be accessed through 64 bit as I am told.
I am wondering how to download and install the 32 bit version of Firefox.

Unless you specifically download a BETA x64 bit, all downloads are x32. There is no official x64 support for Windows yet. Which version do you want to download? The latest is available at http://www.mozilla.org/en-US/firefox/new/. Beta and Nightly at http://www.mozilla.org/en-US/firefox/channel/

Firefox for Windows universal app

Please create a Firefox version for Windows RT/Windows Phone/Windows10/Xbox etc as a universal app. I read about API restrictions on Windows phone 8/8.1 for Firefox from a different thread. I am hoping that with Windows10 this restriction is removed so a universal app for all the platforms can be created. Firefox has been sorely missing from the Windows RT/8/8.1 tablets and Windows phones 8/8.1.
With a Windows 10 universal app Firefox would potentially be able to reach a far greater audience than Windows phone or Windows RT/8/8.1 alone. Firefox is one of the browsers used by millions on the Windows platform daily (32bit and 64-bit as of recently). Please extend it to the other Windows platforms as well.
Thanks

Hi jtletters:
Very interesting idea, thanks for that. I will pass it on to the desktop team (I work on Firefox for Android mostly). I am sure they are at least thinking about it!
Cheers!

I have uninstalled and reinstalled and Firefox for windows 7 will not open. There is no error message--it just doesn't open, even in safe mode. What do I do?

My computer is set to auto update for Windows 7 Home Premium and for Microsoft Office Professional Plus 2010. I am also running Norton 360. There was a major update for Office on 12/10/14 that seems to be when my problems started. This month, every time my updates have caused a reboot, Mozilla has failed to open. I have uninstalled it and reinstalled it several times, and it has only lasted a day or two before it crashes again. This last time it will still not open. All the instructions to troubleshoot seem to be based on the idea that the program is open and just has issues. I can't even get it to open up in Safe Mode.
I have tried to reinstall, and it says that it will launch automatically when the install is complete, but it is not working. Since Norton scans every download before it runs, I'm not certain if that is where the problem is since I never get the window that shows the step by step installer for Firefox.
What do I need to do?

Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. A clean reinstall is not the same as a regular reinstall performed using the built in installer. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from [https://www.mozilla.org mozilla.org] (or choose the download for your operating system and language from [https://www.mozilla.org/firefox/all/ this page]) and save the setup file to your computer.
#After the download finishes, close all Firefox windows (or open the Firefox menu [[Image:New Fx Menu]] and click the close button [[Image:Close 29]]).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
More information about reinstalling Firefox can be found [[Troubleshoot and diagnose Firefox problems#w_5-reinstall-firefox|here]].
WARNING: Do not use a third party uninstaller as part of this process. Doing so could permanently delete your [[Profiles|Firefox profile]] data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be easily recovered unless they have been backed up to an external device! See [[Back up and restore information in Firefox profiles]]. 
Please report back to say if this helped you!
Thank you.
