Is my firefox 64 or 32 bit

Build identifier: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0
I would like to know

WOW64 means it is a 32-bit application on 64-bit Windows. It is the 32bit emulator for x64 systems.
Mozilla does not have Win64 release builds of Firefox yet and not likely for a while still. They do have 64-bit Release builds for Mac OSX (combined 32/64) and for Linux.

I have a laptop with Windows 8-64 Bit, but the download version of Firefox is 32 Bit, how to correct this?

I find that my browser hangs a bit when playing games, don´t know if it might be attributed in having Firefox with 32 Bit instead of one with 64 Bit. Please advise. Thanks in advance

Hi hkmmm, I did read that you had Windows 8, but my point simply was that 64-bit versions of Windows historically support both 64-bit and 32-bit software.
I suggest trying the standard Flash guidance for Windows 7/Vista, on the theory that the plugin behaves similarly on Windows 8.
(1) Disable protected mode (Win Vista & Win 7 & maybe Win 8)
See this support article from Adobe under the heading "Last Resort": [http://forums.adobe.com/message/4468493#TemporaryWorkaround Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?]
(2) Disable hardware graphics acceleration in Firefox and in Flash
(A) [''done''] In Firefox, un-check the box here and restart:
orange Firefox button ''or'' classic Tools menu > Options > Advanced > General > "Use hardware acceleration when available"
(B) In Flash, see this support article from Adobe: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues

Running Firefox 4.0 on Mac OSX 10.6.6, using ATT mail, when I create a new email I get a browser message saying, "This page requires a plugin that can only run in 32-bit mode," and I have to restart Firefox in 32-bit mode. Is there any way around this?

I am assuming the plugin that the Firefox message is referring to is for attaching a file to the email. I say this because at the bottom of a new email it has a link that says "Attach files more easily" which, when you click it, takes you to a setup process where you download an att updater. I ran that and it did seem to change anything. I am wondering if there is anything I can do to make Firefox handle this page without having to restart in 32-bit mode every time.

That means that you need to run Firefox in 32 bit mode if you want to use that plugin.
# Close Firefox
# Open the Applications folder in Finder
# Right click or control-click the Firefox.app icon
# Select "Get Info"
# Select "Open in 32-bit mode"
# Close the "Firefox Info" window
# Restart Firefox

How do you open Firefox in 32 bit?

Hi
I'm using Win7 64 bit & I need to open Firefox in 32 bit. A plugin I need doesn't like 64 bit.
Everything I have found so far pertains to Mac.
How can I open Firefox in 32 bit?
Thanks

Thanks for responding! I am trying to use Sibelius Scorch plugin which is a 32 bit plugin. Every post I have seen on this says that I have to run Firefox in 32 bit for it to work.
I have another pc that is XP 32 bit & it works fine in Firefox, which would confirm what I had read. Any ideas as to how I can use this plugin on my 64 bit OS with Firefox?
Thanks again!

Is it possible to use 32-bit firefox with 64-bit java plugin?

Is it possible to use 32-bit firefox with 64-bit java plugin?
I'd like to use 32-bit firefox and I already install 64-bit java plugin.
Is that a right choice not to install 32-bit java plugin?
Will these cause problem?
Thanks in advance.

Nope - you need the 32bit Java to go with the 32bit Firefox if you want Java to run

How to open Firefox in 32-bit mode for Mac OS X 10.6?

cannot use Firefox in 64-bit mode for IMac running OS X 10.6 as it will not work with banking scanning software.

To set Firefox to always run in 32 bit mode, open up Finder and go to the Applications folder. Control-click the Firefox app and click "Get Info", then select the "Open in 32-bit mode" option.

Is there a firefox for 32 bit computers?

is there a firefox for 32 bit computers?

I have tried several times to put Firefox on my desktop computer. Nothing happens, the task manager says it's running, but it doesn't show up on computer. Is it compatible with Windows XP Pro?

Why does Firefox ignore 32-bit mode setting?

I'm running Firefox 18.0.1 in Mac 10.8.2, but I've had this problem in other versions too. I need FF to run in 32-bit mode, because I often use Google Voice, which requires that. I've already gone to the information window for the application and checked the box that says "Open in 32-bit mode." Seems like that should solve the problem. But it doesn't. Every time I open FF and log in to Gmail, I get a message saying it uses plug-ins that can only run in 32-bit mode, and asking if I want to restart in 32-bit mode. If I just want to check my email it's fine, but if I want to use Google Voice I have to restart the browser. That's annoying, given that there already is a setting for starting in 32-bit mode, and that I've already selected it. Is that setting non-functional, or is there some way to make it actually work?

Firefox may need to use a plugin (possibly Silverlight) that is only present in a 32 bit version if that happens.
Not all plugins support 64 bit and if not then you need to start Firefox in 32 bit mode to use that plugin.

How to roll back to Firefox 3.6 32 bit from Firefox 4 64 bit

I am running firefox 4 64 bit on windows 7. However my remote citrix connection for work needs a 32 bit browser. How can I install a 32 bit version on my PC when my OS is 64 bit?

I can tell by your user agent string that you are using the 32 bit version of Firefox 4.0.1
Your user agent string is '''Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0.1) Gecko/20100101 Firefox/4.0.1''', the WOW64 part means you are using a 32 bit version on 64 bit Windows. A 64 bit browser would display win64 instead.
All release versions of Firefox on Windows are 32 bit, though a 64 bit version is being developed.

Is there a different version of firefox for 64 bit windows 7? if so, where do i go to get it. I try installing and it doesn't work.

I had an issue with my school website today, they said i could have issues with the new version of firefox, so i decided to go back to the 6.0.2 version of firefox. I open and run the file to start the process of setup, and it extracts the file. It then asked me how i wanted to run the file, and then, it just does nothing. I cannot even find it on the computer, so i don't know if it is just not installing at all or what. I have no idea what to do about this. I am currently running 64 bit vista, and i dont know if i just got the 32 bit version, or what.

EWallet crashing when using Firefox on 64 bit Windows 8.1

Hi there,
Since I upgraded my laptop recently to a 64-bit HP Envy running Windows 8.1, I’ve been having trouble with eWallet (a digital wallet for passwords) using Firefox V35.0.1.
In case you don’t know eWallet, it is possible to store passwords, user-id’s and sign-on web page URLs in a card format. When you click on the URL, it populates the fields in the sign-on page.
I am having the same problem on a 64-bit Dell Inspiron laptop my wife uses
eWallet works seamlessly on 32-bit Win XP.
eWallet works on both the 64-bit machines using Internet Explorer and Chrome, but not Firefox.
After many emails back and forth, several complete removals (using Revo Uninstaller) and re-installs of both eWallet and Firefox, this is the conclusion of eWallet Support….
It looks to me like the Firefox installation still isn't quite right on your PC. If you look at the text file you sent me, you'll see on line 43[of the registry dump I sent them] that firefox is referenced under the "Program Files" folder -- but in other places in the file, it's referenced under "Program Files (x86)". My guess is that eWallet is trying to launch firefox using the path Windows is giving it (C:\Program Files\Mozilla Firefox\firefox.exe), and firefox is not actually there.
Please note that this area of the registry is Microsoft's, not ours -- we don't change anything in it, we merely use this area for its intended purpose: getting the path to the appropriate browser. I can't explain why Firefox isn't installing properly, but it's outside the scope of eWallet to be able to resolve that particular problem.
My understanding of what they are saying is that Firefox is not installing correctly for some reason.
I have also tried starting Firefox without any extensions or plug-ins, again no success.

Hi @curtisa, @guigs2 and @rmcguigan,
Thanks for your responses.
I managed to get eWallet working correctly for 24 hours approx. by uninstalling Firefox, running CCleaner, deleting all Mozilla references on my system drive, scanned for virus using Win Defender, SuperAntiSpyware, and SpyHunter, (nothing reported) then again downloading and installing the current version of FF to "Program Files (x86)".
However next morning, it had failed again.
I checked the Windows event log and it shows an error with a Source of .NET Runtime. The application is eWallet.exe, Framework Version V4.0.30319, Exception Info SystemAccessViolationException.
I'm not sure what that all means, and would welcome any further suggestions.
Cheers
Steve

Firefox.exe (32 bit) continues to run in the background after closing, Im running Firefox (64 bit).

After browsing the web and downloading items from websites, with Firefox's built in download manager, then closing Firefox I'll have to open my task manager and manually stop the 32 bit .exe. Im running Firefox (64 bit) on a Win7 (64 bit) system.

How do I reset Firefox to 64 Bit mode?

Netflix required a reset to 32-bit mode, but now that I'm here, I can not reset it in Mac OS 10.6. I can get into FF's information, and check the "start in 32-bit mode" box, but I'm stuck. I can't get it OUT of 32-bit mode.

Is this in your Google search results? You might need to delete the cookies Google has set on your Firefox.
First, save any pending work (e.g., draft Gmail messages). While viewing a page on the site, try either:
* right-click and choose View Page Info > Security > "View Cookies"
* Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"
In the dialog that opens, you can remove the site's cookies individually.
Then try searching again. Does that help?

Firefox is leaving bits of its menus all over the screen--how do I fix it?

Any graphic or menu that exceeds the boundaries of the Firefox window may leave bits behind. Example:
http://lordzox.com/temp/ff4litter.png
Over at the right side, you can see that not only did the bookmark display not get cleaned up _outside_ the window, but it even made the window controls disappear.
Refreshing the display will clear the mess outside the window; minimizing and re-expanding the Firefox window will clear it inside. But it just keeps happening.

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
In Firefox 4 [http://kb.mozillazine.org/Safe_mode Safe mode] disables extensions and disables hardware acceleration.
* Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

Firefox is a bit slow all through; can I display message in my new web site that visitors should view it with Firefos?

I will be setting up a new web site soon. May I put a note and a link on one of the pages advising people to utilize the site through Firefox? The latest Firefox seems to be a bit cumbersome with loading pages; I have WinXP Pro.

Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache.
Note: ''This will temporarily log you out of all sites you're logged in to.''
To clear cache and cookies do the following:
#Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
#Under "Time range to clear", select "Everything".
#Now, click the arrow next to Details to toggle the Details list active.
#From the details list, check ''Cache'' and ''Cookies'' and uncheck everything else.
#Now click the ''Clear now'' button.
Further information can be found in the [[Clear your cache, history and other personal information in Firefox]] article.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
<b> To Enable SafeMode </b>
*You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
*''Once you get the pop-up, just select "'Start in Safe Mode"''
If it works in Safe Mode and in normal mode with all extensions (Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: "Firefox > Quit Firefox"; Linux: "Firefox/File > Quit")

I'm updating my plugins and java platform says Firefox is 32 bit. Is this correct? I'm running Windows7 home premium 64 bit.

At the java update site it says my Firefox 4 is 32 bit and I will have to download both the 32 and 64 bit versions. I have IE9 which is both 32 and 64 bit versions. My primary browser is Firefox 4. My OS is Windows Home premium 64bit. I personally have no problem with the 32 bit but I am curious to know.

Flash Player is a browser add-on, not an executable program.
If you need to open a local SWF file you will need the standalone player (Projector) from http://www.adobe.com/support/flashplayer/downloads.html
Note that the download is the player, not an installer, so you will need to make the file association manually.

Is my firefox 64 or 32 bit
