Firefox crashes before it starts

since 01/01/2012, i can´t use firefox anymore because it crashes before i can open it. everything i see is a pop-up window which says that I can report it to you.
i already tried everything which is written on your support page (trying to open it in safe mode e.g.), but it still crashes then.
my antivirus programme told me, there was a file with kind of a virus the day, when firefox crashed for the first time

Firefox 7.0.1 Crash Report [@ js::Bindings::getLocalNameArray(JSContext*, js::Vector<JSAtom*, int, js::TempAllocPolicy>*) ]
* https://crash-stats.mozilla.com/report/index/2f7a02f0-334b-47ea-85bc-6403f2120103
This crash is fixed on Firefox 9, please upgrade your browser to Firefox 9 and check

FF was working just fine... I was on Facebook... left my computer (Mac OS X 10.5.8) for about an hour (everything was left on)... when I got back FF had crashed, I did the usual, sent report and restarted... the icon would bounce, looked like it would start and poof crash report... I tried a few times same thing, before FF would even start it crashed... left it for a while... came back, same thing... I deleted it and reinstalled it, same thing... it's been 2 days almost 3 now, and it is still the same thing... I tried to find the previous version 3.6.3 (which worked just fine) and can't seem to install it... please help... I prefer Firefox than any other browser... I would really appreciate it if you would look into this problem.. I understand a lot of users are having all sorts of problems with the new version 3.6.4... Please help... Thank you...

Firefox crashes before starting in Win 8.1

Was using Firefox then shut it down. Opened PhotoImpact Pro 13 and was using that when about 10 minutes later I reopened Firefox. It crashed without opening. Couldn't get it to start. Other browsers worked fine. Searched internet, tried resolutions like: Restarting PC, refreshing FIrefox, troubleshooting PC, starting Firefox in Safe Mode (wouldn't start), deleted Firefox, did clean reinstall, nothing worked. Even replaced wifi net connection with cable, in case wifi adapter was interfering somehow.
I'm running Windows 8.1 64-bit.

Hi, 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.
#On the keyboard, press [Windows] [[Image:Windows key]] + [R]. This should bring up a Run window that contains a text field.
#In that text field, type '''%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!

New widows 7 install on amd phenomx6 64 bit firefox 3.6 crashes as soon as it is started also will not start in safe mode it crashes before it starts. it will run when windows is in safe mode

this is a brand new system from zt systems. it came with almost no software installed. no toolbars or anything, only trial of microsoft office.
I don't think that it even generates a crash report.

Can you provide me with your Crash ID? See https://support.mozilla.com/en-US/kb/Firefox+crashes+when+you+open+it#Getting_your_crash_report . Please post them here
Your crash ID is after ''bp''
'''Crash troubleshooting'''
Add-ons
One of your add-ons might be the culprit. Try running Firefox in [[Safe Mode]] with all add-ons disabled. If that solves the problem, see [[Troubleshooting extensions and themes]] and possibly [[Troubleshooting plugins]]
Are your plugins updated?
Check this by going to http://www.mozilla.com/en-US/plugincheck/
Are you using the newest version of Firefox?
It is important you use the latest version of Firefox because it includes stability and security updates. The latest version of Firefox can always be downloaded from http://www.getfirefox.com. You can check if you are using the latest version of Firefox by going to Help | About Mozilla Firefox. If you are not, see [[Updating Firefox]]
Malware
Different types of Malware can cause Firefox to crash. For more information, please see [[Is my Firefox problem a result of malware]]

Firefox crashes - will not start at all

If I try and start Firefox all I get is the Mozilla Crash Reporter, if I try and restart Fireofox from the Crash Reporter screen all I get presented with is the Mozila Crash Reporter again. If I try and submit a crash report the Crash Reporter states "there was a problem submitting your report", hence no crash ID available.
The issue started when I updated my old, maybe version 5, Firefox with version 9, since then I have been unable to start Firefox.
I have tried unistalling Firefox, including deleting personal settings, and restarting the PC in between deleting Firefox and attempting to reinstall it. None of this works. Firefox will also not start in safe mode.
Mozilla Crash Reporter details added to the below Troubleshooting Information info box.

Does Firefox start if you boot Windows in Safe mode (press F8 on the boot window)?

Firefox Crashes Silently at Start-up

Firefox has been crashing on start-up for the past few weeks. I've tried safe mode, a profile reset, a clean re-install, and several clean installs of different versions (4.0, 4.1, 5.0 and 6.0b1) in attempts to resolve this, all without success. Occasionally Firefox will start successfully and will stay stable once it has, but this is a very rare occurrance. I've run scans with Avast Antivirus, Malwarebytes and SUPERAntiSpyware, which all came back clean.
The only changes to the system around the time the problem started were CPU and RAM upgrades (with new, known-good parts) and a BIOS update required to use the new CPU. Firefox is the only program crashing in any way/shape/form since this upgrade.

Hey Seifer10357,
Have you tried starting Firefox in Safe Mode? Hold down "shift" while Firefox is starting up. If the crash doesn't happen in Safe Mode, you should read [[Troubleshooting extensions and themes]].
There is also a lot of useful stuff in the [[Firefox crashes]] Knowledge Base article. If you've recently upgraded, you might want to check out [https://support.mozilla.com/en-US/kb/latest-firefox-issues#w_firefox-crashes-when-i-start-it this article] as well.
Hopefully this helps!

Firefox crashed before I could load my previous session - how may I restore it? I have backed up relevant session files, but have no idea how to use them.

I was using Firefox shortly before deciding to restore my previous session (100+ tabs!), but the browser froze and went blank with the "Not Responding" label on top. This happened to me before, and I decided to just quit the session. I knew that I would lose the session I wanted, but I backed up the important session files found in the Mozilla directory (or at least whatever has "session" and "restore" in its name) while the browser was stuck (before quitting).
What I'd like to understand is HOW TO USE these files to get my session back. I've tried replacing the session files with the back-up copies to no avail. Once long ago I managed to recover a session successfully, but with Firefox constantly changing, I may have lost touch with this.
I use Firefox 34 and Windows 8.1, but I'll need others' help in identifying the session backup/restore files I need to use from the ones I backed up.
I believe that the "recovery.bak" is vital, because it contains the tab/page names I was viewing.
I would greatly appreciate whoever would help me in this, especially if they can teach me the proper methods to follow if this ever happens again (which most likely will!)

You can look at this post in this MozillaZine forum thread about inspecting a sessionstore file and possibly extract URLs.

You can open the Browser Console (Firefox/Tools > Web Developer).

Our firefox crashes as it starts up. Can't find any solutions that work on your website. Have to have firefox for business purposes. Please help!

Hello,
We have used Firefox for years. We have Mac 10.6.8 and Firefox 11.0. It has been working fine until today. I have no idea what could have messed it up. Now every time we try to start it up an error box appears announcing that the application has crashed. My computer has already sent you quite a few error reports. I have to have Firefox for business purposes. Would appreciate help as soon as possible.
Thank you,
Nikol Jones

Please do the following:
Visit www.getfirefox.com in safari, download and install Firefox 17.0.1. Try to open Firefox. If that doesn't work, follow these instructions:
#Open the Finder by clicking the smiley face icon in the dock.
#Navigate to the following directory: ''~ / Library / Application Support / Firefox / Crash reports / submitted''.
#Now, you should see a list of files that contain reports. Click the gear icon in the toolbar (or open the ''View'' menu), then select ''Arrange by'' > ''Creation date'' 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 into the reply window on the forums.
Thanks in advance!

Firefox crashing before download finishes and showing unknown time remaining

whenever i want to direct download through firefox, it says unknown time remaining but it still downloads then firefox crashes out of nowhere

It is possible that anti-virus software is corrupting downloaded files or is interfering otherwise.
Try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.
See:

Firefox crashes before it can start up, can't even get to safe mode.

Hello,
Firefox automatically downloaded and installed an update this morning and now it won't start at all. I've tried starting in safe mode (shift-clicking to start), but I can't even get through there. It's just crash after crash after crash and I'm quickly losing patience.

After doing more digging, I found that updating my version of RoboForm was the fix. At least so far... we'll see how long it lasts!
If you're running RoboForm and can't get in, try to update RoboForm from IE, then try again.

Firefox crashes before it can be open, just started today and have no idea how to fix it.

I was using Firefox when it first crashed, now when I try to restart it the Motzilla Crash Reporter window opens. I have no idea how to fix this. I tried to follow directions on-line (I'm not very computer savvy) but my signature/ID what ever is c27da8ef-4370-4963-9c18-cb5d52100726

Firefox crashes everytime I start it and Trend Mirco Pops up with a Malicious URL

Every time I start firefox it hangs or locks up with Not Responding. I've tried it in safe mode but still have problems. Also just before the program hangs my Trend Micro window pops up and says that it blocked a threat. http://convertnews.ru/kernal/index.php. These problems only started a two weeks ago. I've run multiple virus scans and which don't come up with any problems. I can't get a crash ID because it never asks to report the crash. This problem is happening on ALL my computer, laptop, home computer, work computer. Everyone that uses Firefox. I've disabled the add-ons but still the problem persists. Usually it happens when I first start up Firefox for the first time of the day. Getting really tired of these problems.

Try renaming the folder "Elements Organizer" and "Online Services". These folder are present at C:\Users\<current user>\AppData\Roaming\Adobe. After renaming these folders, application should launch without crashing.

I by mistake chose to insall the weather app for Firefox on Apple iMac. I cannot uninstal from add ons since firefox crashes before then. Unable to use Firefox in safe mode. Help!

Basically I recently installed Firefox 3.6 on my Mac Laptop, only 3-4 months old, so latest Sea Leopard OSX System whatever
Anyway once installed I decide to have a theme, then add some add on applications. This seems to be the problem
When I first tried to run it all the apps opened home pages and I kept trying to close them as they did
Next time I got less pages but then I could not access the Tools>AddOns menu before the Firefox browser crashed
What seems to be happening is that the Weather app takes forever to load, my Apple Mac goes into the circle (thinking) mode which means I cannot activate any menus or move my mouse. Then by the time I try and type in say google in the blank www URL address the browser crashed. I have tried going into safe mode using the Option but makes no difference
If I can somehow instal the irksome weather app or get access to the Tool >Add ons menu and uninstall each of the several apps I have daftly installed I know I can get a solution
Any help or suggestions appreciated since I still think Firefox is cool:-). its the apps or some of them that suck!

Maybe you did't understand my previous statement. There are no crashes in FF 3.6, There is no previous evidence FF 14 was ever here, I completely uninstalled all trace of Firefox, no app data, no preferences, no cache. I will upgrade to FF14 so I can send IDs,
so here ya go.
