Firefox will not open i get mozilla crash reporter and nothing else

When I try to open Mozilla the crash reporter comes up. The restart firefox option does not work

Hold down the shift key when starting Firefox, this will put you in Safe Mode. If it starts ok then you have an extension or a plugin that is causing the problem. If this is the case then proceed here:

Please help resolve...

Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox and any leftover program files and then reinstall Firefox. Please follow these steps one by one:
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu) and confirm all upcoming messages.
#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.
Please report back to see if this helped you!

Firefox will not open, it gives me this cod and would not turn off, Error on switching in renew: NS_ERROR_UNEXPECTED, Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.getCharPref] id: none

I restored my computer to earlier time and I did an other restore but to latest time and since then every time I click on Firefox short cut this window comes up with the same cod and I can not turn it off unless turn off or restart my laptop, I did delete the Firefox few times and reinstalled it but did not change anything, still I get the same cod,
Error on switching in renew:
NS_ERROR_UNEXPECTED, Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.getCharPref]
id: none

Some how I solved my problem by opening a user account and downloading Firefox 4.0 beta and installing it, I did try it, worked fine, so I did close the user account and did go back to my own account(switched user), the main page that I had problem with Firefox which would not open, I dabble click on Firefox it start working again!! I hope that solves your problem too.

Firefox will not open, it goes right to crash reporter, and it will not open in safe mode(crash reporter again).

I added adblock, that seemed to work OK. The same day I was tracking down slow download speeds with my ISP and they had me go to, I think...I can't remember to well, the tools menu and erase cookies, passwords, etc. I don't remember what else was erased,
in order to "speed up my browser". Maybe I shouldn't have blindly done that. Anyway, when I tried to start Firefox it just goes straight to the crash reporter. It opens fine under Admin and other users.

Uninstalling and reinstalling Firefox doesn't usually solve anything, because most problems are contained in the profile.

Firefox will not open just say it has crased and to send a report.

I downloaded AVG 2011 and now Fire Fox will not run it says that it has crashed and sends a report, it will not open at all.

Have you tried clearing the cache? See suggestions in this article --> https://support.mozilla.org/en-US/kb/websites-dont-load-troubleshoot-and-fix-errors
The latest version of Firefox is 13.0.1; it appears that you are using Firefox 12.

Firefox will not open certain websites, unless I close and restart the browser. Anyone hear of this ?

Some webpages, for example newegg.com, will not open at all. But if I close ff and then restart ff - newegg.com will load up almost instantly. Yahoo's pages have problems as well - especially if there is a video with a news article. Many times - there simply wont even be a placeholder. I will read the article - and then realize there should be a video accompanying it - I'll have to view in IE - which I hate.

I can press ctrl for a new tab but otherwise a new tab does not open. I actually need help regarding this new Synch which apparently will be in Firefox automatically in an upcoming version so I am asking how that will synch with people who use LastPass-of course because I use this very successfully and really am not eager to change the set up that I have in place at this time.
I have read through endless FAQ trying to find anyone else who has this question or concern but have found nothing. Can you please tell me how that service will get along with LastPass which does basically the same thing as Synch-it is probably spelled wrong as it looks wrong to me but if I click back to where this issue began, I will lose all of this question so please respond for the upcoming service synch.

Firefox crashed now when I try to open it get Mozilla Crash Reporter

''Duplicate post, continue here - [https://support.mozilla.com/en-US/questions/788208]''
Firefox crashed unexpectedly. ow when I try to open it all I get is a Crash Reporter box. Dont have a location bar to enter a crash ID.

Try a clean (re)install:
* Download a fresh Firefox copy and save the file to the desktop.
* http://www.mozilla.com/firefox/all.html
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data if you uninstall the current version.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
* It may not be necessary to create a new profile, so first try if it works with your current profile and if not then create a new profile.
Your current bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Firefox will not open any webpage - including google, youtube and firefox help.

Firefox won't open anything. This includes support.mozilla.com - I am currently using my back-up browser, Internet Explorer.
Firefox is enabled to access the internet, and browser cookies are not blocked.
All it says every time I try to open any webpage is 'Firefox can't establish a connection to the server at [address of site].' and 'Unable to connect.'

After upgrading, sometimes your firewall will not recognize the new Firefox version and, therefore, not allow it to access the internet. To remedy that situation,
#you must remove Firefox from your firewall's allowed applications list,
#then restart firefox, go to a website, the firewall will detect the new Firefox version and
#then give the necessary permissions for your firewall to allow Firefox access to the internet

Firefox will not open at all on macbook pro and then crashes mac entirely.

My firefox wont open when I've clicked the icon, though there is a little blue light underneath it. I've installed and re-installed it and still not working. When I do click the icon in the dock my entire macbook freezes and I have to manually restart it. I'm afraid my knowledge of stuff like this is exceedingly limited, I've read through numerous problem solving posts but I just don't understand the instructions others have given. This has previously happened to my firefox and i renamed the .exe(?) file and that made it work but I can't remember how I did it/can't find the post that helped me. I'm sorry to be so basic but I don't know anymore and want my browser working again!

You won't want Firefox to be a .exe file, thats for windows. Make sure its extension is .app. You can do this by going to Finder>Applications>Firefox>the right click and click the "Get Info" button. Then, about halfway down will be the file name with the extension. Change it to Firefox.app if it is not already like that.
Also, you can check out this [https://support.mozilla.org/en-US/kb/firefox-keeps-crashing-startup support article] if this doesn't help.
Have a great day!!

Firefox will not open on my mac; crashes whole system when I try to open!

Firefox crashes my whole system when opening for my Mac 10.5.8

Unfortunately, Firefox 4 requires either MacOS X 10.5 or 10.6. For 10.4, you can run Firefox 3.6 from here:

Firefox will not open when I click the icon and windows task manger indicates firefox is running.

I can't open firefox. I click the icon, my cursor shows Firefox is loading, then nothing happens, the screen remains the same.

Hi Iekard.
Press CTRL+SHIFT+ESC to see if the firefox.exe process is running. If it is, terminate it and try to run Firefox again.
If that doesn't help, try running Firefox in safe mode. If it works like that, maybe it'll work again in normal mode.

Firefox will not open because of this error message...[JavaScript Application] Error on switching in renew: NS_ERROR_UNEXPECTED, Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.getCharPref]

when this error box opens the only way to close it is to shut the firefox process

Some how I solved my problem by opening a user account and downloading Firefox 4.0 beta and installing it, I did try it, worked fine, so I did close the user account and did go back to my own account(switched user), the main page that I had problem with Firefox which would not open, I dabble click on Firefox it start working again!! I hope that solves your problem too.

Firefox will not open at all. I only get the Mozilla Crash Reporter over and over.

After updating yesterday, Firefox will not open. I repeatedly get the Mozilla Crash Reporter. I've scanned my computer for malware, I've tried to open it in safe mode (it won't), I've completely uninstalled and reinstalled Mozilla, but nothing works. Each time I reinstall, I still get the Mozilla Crash Reporter. The program will not open at all.
I ran my crash ID. Here is the info: bp-eff196eb-ed21-45ee-83c6-e0fc42130123

hello, this crash is caused by Websense Endpoint security software that is running on the system. please try to install all the updates for this program that are available...

Please help - Firefox will not open. library - applications - and no firefox is listed to get to my profile manager. . What's next?

firefox has been running slower. When this happens I'll reboot my computer and this speeds up firefox. When I restarted the computer firefox would not open. Just the spinning wheel with no access to the tools.
After I force quit - it says ignore or notify/report to apple. I tried sending a report, and it ques up the box with details, system config, etc... but when I click on send - it will not let me send one - I've never been unable to send a report before.
I uninstalled, then reinstalled. Upon opening I get the spinning wheel and nothing happens - I need to force quit. I see on this mozilla help site that I need to update my profile manager. I followed these instructions - Finding your profile without opening Firefox Open Finder and go to your home folder. Note: your home folder is usually the name of your Mac user account From your home folder open /Library/, then /Application Support/, then /Firefox/, then /Profiles/. Your profile folder is within this folder. but when I got to library - application support - there is no firefox listed.

You can do a disk check with the chkdsk.exe program.
If you run the chkdsk.exe program from a cmd.exe Command window then you can read the response from the chkdsk.exe program.
Open a cmd.exe window: 
Start > Run: cmd.exe <press Enter>
At the command prompt (>) type or Copy&Paste: chkdsk.exe /f /r <press Enter> (put a space before /f and /r)
If you get something like: Would you like to schedule this volume to be checked the next time the system restarts? y/n then answer the question with "Y" and close all programs and reboot the computer.
A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.
