Firefox 37.0 crashes on start-up

Since installing the upgrade to v37.0 yesterday, I have been unable to start Firefox. It goes straight to the 'We have a problem' window asking me to submit a crash report

hello manofmann, please look out for a firefox 37.0.1 update that is going to be released soon in order to adress some startup crashes on windows as this might apply to your issue as well...

How do I stop Firefox looping from crash to start when it won't stay up long enough to enter into?

Ever since the latest update Firefox hasn't worked properly. It has the MyPoints latest toolbar attached to it and allowed me to view it then suddenly vanished. After that it started this open/crash loop that is so fast I can't click into the browser to try safe mode or to even access the toolbar. I uninstalled Firefox and reinstalled. Everything got worse and the MyPoints toolbar suddenly reappeared. A lot of extraneous programs were downloaded without my permission and it's taken days to uninstall all of those. I'm on a refurbished Windows 7 HP and just finished ALL the newest Windows updates. Tried Firefox again, same problem. Unless I can actually access Firefox (the mouse is supper sluggish when trying to click in the Firefox browser as if the browser is preventing access) I can't do any of the "fixes" suggested in your support forum. I have uninstalled and re-install Firefox about 4 times now but nothing changes. Yes, I deleted the Mozilla file in "programs". I can't do a screen shot because of the inability to access the window in the time allowed before it crashes and there is nothing to see but the opening window - no error messages. No crash report comes up. Just an endless loop of open/close/open/close etc.

Are you sure you didn't get an unofficial installer? You may need to visit the Windows '''Control Panel''', Uninstall a Program. After the list loads, click the "Installed on" column heading to group the infections, I mean, additions, by date. This can help surface innocent sounding bundle items that snuck in with some software you agreed to install. Take out as much trash as possible here.
Then, to ensure that your program folder is not contaminated, I suggest:
'''Clean Reinstall'''
We use this name, but it's not about removing your settings, it's about making sure the program files are clean -- and do not contain alien code files. As described below, this process does not disturb your existing settings. Do NOT uninstall Firefox, that's not needed.
(1) Download a fresh installer for Firefox 37.0.1 from https://www.mozilla.org/firefox/all/ to a convenient location. (Scroll down to your preferred language.)
(2) Exit out of Firefox (if applicable).
(3) Rename the program folder
''(32-bit Windows folder names)''
C:\Program Files\Mozilla Firefox
to
C:\Program Files\OldFirefox
''(64-bit Windows folder names)''
C:\Program Files (x86)\Mozilla Firefox
to
C:\Program Files (x86)\OldFirefox
(4) Run the installer you downloaded in #1. It should automatically connect to your existing settings.
Any improvement?
Note: Some plugins may exist only in that OldFirefox folder. If something essential is missing, look in these folders:
* \OldFirefox\Plugins
* \OldFirefox\browser\plugins

Firefox stops and crashes when starting a search

When I open bookmark pages everything works fine the problem occures everytime I do a google search and it stops operation with 'not responding' error.
Finding it very frustration, only happens since I upgraded to version 4. Other search engines like Internet Explorer works fine. If the problem is not resolved I will have to go with IE all the time.

Is your Win7 32-bit, or 64-bit?
For Win7-64, and the GeForce 9 Series, this is appears to be the latest driver: http://www.geforce.com/drivers/results/59641

Firefox crashes on start-up; cannot get it to work. Any detailed solutions to try?

I've read through so many helping websites but I just can't find a solution to fix Firefox, it constantly crashes upon start-up. So I can't activiate Safe-Mode, or open it up or anything to fix it.
I also suspect that this rundll32.exe host has to do something with it. The messages came right after Firefox crashed. Should it be deleted?
Please help. This is bothering me so much. I'd appreciate any comments. Thanks!

Since a few days we have a lot of crashes with [http://www.trusteer.com/product/trusteer-rapport Trusteer Rapport]. If you have this program, try to disable it and see if that stops the crashing. 
You can stop Rapport using Start Menu > Programs > Trusteer Rapport > Stop Rapport 
You can ask their helpdesk when an updated version of their product will be made available or, if you don't need this software, uninstall it. 
http://www.trusteer.com/support/en/report-problem 
If you do not have Rapport, then we need to have a crash report ID. When you send Mozilla a crash report it just puts it in a giant database. We have no way of looking it up without the Report ID. I have no idea what is wrong without looking up the crash report. Please get the Report ID of your latest crash report.

crash.....crash....crash...
reinstalled 3.6 and stoped the auto updating for now.'''bold text'''

If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
* [[Troubleshooting extensions and themes]]
Your above posted system details show outdated plugin(s) with known security and stability risks that you should update.
# Shockwave Flash 9.0 r280
# Adobe PDF Plug-In For Firefox and Netscape 8.2.6
You can find the old Flash plugin file NPSWF32.DLL in the plugins folder within the Firefox program folder (C:\Program Files\Mozilla Firefox\plugins\) and remove that file.

Hi Max,
Congratulations, at least you made a stab at solving the problem. I think a lot of users used to glance at that KB article ([[firefox crashes]]) and give up trying!
Hopefully the crash instructions will be further modified soon, (some of us consider the following is an [/kb/Firefox%20crashes/discuss/1855 omission] that needs correcting) have a look at this article for an explanation of how to get the crash ID from your OS even without using firefox:
* http://kb.mozillazine.org/Breakpad#Location_of_crash_reports
The XP OS is likely to use smoke and mirrors to make it look like you have a totally
separate installation of firefox for each account, but normally you have the one set of (most) program files, and then for firefox separate [[profiles]]. So this indicates the problem is likely to be in the profile of the problem account, or down to a plugin, malware or other issue relating to that account. (I note you have already scanned for malware with MSE, that should detect a particular trojan that is a top cause of firefox 6 crashes)
If you create a new clean profile in that account hopefully it will solve the crash problem, you can then address the issue of copying settings, bookmarks. passwords etc back. BUT before attempting that ensure that you disable all plugins, ([[safe mode]] does not disable plugins) if you have not already done so. Some plugins may not show up in Firefox's list, you may need to look at the OS program lists.
I note you mention banking, a particular utility ''IDvault'' (I think Comcast supply it) has been causing crashes. Are you using IDvault ? (IDvault should be fixed soon bug684748; version 1.0.627 may have been fixed, but standalone version 5.9.627 has not yet been fixed )

Do a malware check with some malware scanning programs on the Windows computer. 
You need to scan with all programs because each program detects different malware. 
Make sure that you update each program to get the latest version of their databases before doing a scan.

Firefox crashes when starting up on Win2k3 Terminal Server

Firefox 3.x works, however after upgrading to 10.0.2 it will crash whenever starting up.
Platform: Windows 2003 Terminal Server with Citrix.
We have excluded the firefox.exe from the ctxhook and it doesn't help (we know this fixes crashing on startup on Xendesktop deployments).

Thanks for pointing out that crash-stats website. DgApi.dll is Digital Guardian by Verdasys. Essentially monitoring software that the company uses to make sure users are not doing anything they shouldn't. Disabling that fixed it.

Firefox continually crashes when started up.

I open Firefox, and it crashes 5 seconds later. During those five seconds I click on 'Restore' and then it still crashes. After a few crashes I get the option to start in safe mode or restart, when I open in safe mode it still crashes. I haven't tried to reset it as I would like to keep all my settings...

We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.
#Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
#In that text field, enter %APPDATA% and press Enter. An explorer window should open.
#From that explorer window, double-click on the ''Mozilla'' folder, then double-click on ''Firefox'' and then on ''Crash reports''. Double-click on ''submitted''.
#Now, you should see a list of files that contain reports. Go to ''View'' > ''Arrange Icons by'' > ''Modified'' to get the most recent files at the top of the window.
#Open the most recent 5 files with a text editor and copy the IDs.
#Paste each ID with '''bp-''' into the reply window on the forums.
Thanks in advance!

Firefox crashes on Start-Up

Hello!
I downloaded the latest version of Firefox for Windows XP but it always crashes on start-up. Mozilla Crash Reporter appears. I am not able to start Firefox in safe mode.
My latest crash ids are bp-9fdcf812-70e4-4025-97b1-4c7592130430,
and bp-74c78b9f-ad72-446e-aa0a-d8aef2130429.
I immensely appreciate any assistance you are able to provide. Thank You!

hello, from the crash report you've submitted it seems like the crash might be adware/malware related. the file on your pc causing the crash is named ''datamngr.dll''.
first, please go to the windows control panel / programs section and see if you have any toolbars, imesh, MediaBar, data manager or other similar suspicious programs installed - if so remove them...
afterwards please run a full scan of your system with different tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes], [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] & [http://www.microsoft.com/security/scanner/default.aspx microsoft safety scanner].

How to reset firefox profile if it crashes on start (also safe mode)

Hello,
I need to know how to make Firefox do a profile reset when it crashes on start even in safe mode. It starts fine with a new profile.
I had this before today, and then after the 3rd crash report send, a popup offered me a solution to reset my profile while retaining the most important settings. I tried that option and it worked. But I could no longer sync my password with the new sync because of a master password set. I find this a show stopper, so I did a profile restore (mozbackup), I wish I didn't have.
I now have the same problem again with Firefox crashing, but it no longer offers the popup with a solution by trying safe mode (i did manually doesn't work) or resettting the profile.
I need to know a command line switch the make Firefox reset the profile while retaining the important data or how to force it show the pop-up.
Thanks a lot, I'm really pulling my hair out over this and need my Firefox experience back!
Thank you
Regards

Note that a profile created via a reset still can carry over issues because some data is recovered automatically.
If you use the Profile Manager then you get a completely clean profile and if that works then you can copy files yourself to the new profile or possibly try to identify what is wrong and repair your previous profile.
You only see button to Reset Firefox on the "Help > Troubleshooting Information" page and in the Safe Mode startup window if you use the profile that is marked as Default=1 in the profiles.ini file (Profile Manager).
If you do not have the "Reset" button then either use the Profile Manager to create a new profile or use the Profile Manager to start with the current default profile to get the Reset button in Firefox.

Firefox keeps crashing on start-up

Since Sunday evening (3-3-13) Firefox immediately crashes when I try to start: The windows that is opened just freezes and sometimes it doesn't even open at all (although the process is running).
Curious thing is that when I remove Firefox and re-install it, it works completely fine UNTIL I close the browser and try to open it again. Then it's back to crashing again.
Firefox also crashes when starting it in safe mode and it even crashes if I try to make a new profile. Basically, every Firefox thing crashes. When I boot Windows in safe mode the browser runs fine again though.
No crash reports are created so I can't provide those.

Hello, if it works in Windows Safe mode there is a problem with other software, likely security software or a system driver, that is running on your pc. Make sure that you have the latest updates of your security software.
If you like use the Autoruns utility and check which software and services gets started, but be careful if you want to disable a specific service : http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx
thank you

Firefox goes to crash report and will not start when I try to open it

Crash ID: bp-9dc68df0-f096-454c-82c3-e32bf2130531
Every time I try to open Firefox, it immediately goes to the crash reporter which says "We're Sorry. Firefox had a problem and crashed. We'll try to restore your tabs and windows when it starts."
I've ran Anti Malwarebytes, Super Antispyware, Kapersky Security Scan, Microsoft Safety Scanner and Spybot and none of them seem to work. I have, also, tried completely uninstalling and reinstalling without success. I have included my Crash report for you to review. Please help me with this because I am completely out of ideas.

That is a problem with the audioses.dll file: ''Firefox 21.0 Crash Report [@ audioses.dll@0x2d36 ]''

Create a new profile as a test to check if your current profile is causing the problems. 
See '''Creating a profile''':

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem
