Firefox won't open unless i create new profile.

Well, basically firefox won't start unless i open the profile manager and create and/or use a newly created profile. However, if i try to open firefox again after closing it with the same mozilla profile it just won't start. The mouse will briefly display a loading symbol but nothing happens. Google chrome and internet explorer work just fine if that helps.

If you check the Windows task manager, is Firefox doing anything in the background, or just frozen?
You can use Ctrl+Shift+Esc to open the Task Manager, and check the Processes tab for firefox.exe. Sometimes Firefox will hang when shutting down, and then be prevented from restarting. Other times, it may hang starting up due to configuration issues. If you don't find firefox.exe at all, that could indicate a silent crash.

Firefox won`t open unless refreshed

Just this morning, at times Firefox 28 won`t open unless refreshed is pushed. Also, after refresh it still won`t open sometimes. Any ideas?

What do you mean with refreshed?
Do you need to click the Reload button on the location bar or do you need to start Firefox another time because Firefox closes without opening properly?
It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container 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 and the updater process.

Firefox won't open unless i close the one already open

firefox won't open i need to close the one that is already open. i have nothing running or left open in firefox.

I will only close the browser by using your suggestion, File > Exit, from today on, and see what happens. Thank you for your expedient reply.

Firefox won't open, I've deleted old profiles, deleted all Firefox files and gone through all fixes. It still won't run.

Firefox stopped working this morning. I've gone through the process of deleting the old profile and uninstalling Firefox, then reinstalling it. It worked for about 10 minutes then disappeared again. I've gone through the whole clean reinstall and new profile process but can't get Firefox to work at all. This is really frustrating as I've spend over an hour trying to sort it out.
What can I do now?

Rather a difficult question to attempt to answer, as you obviously have already tried the obvious solutions.
Often it is security software or Firewalls interfering especially after a Firefox update. Deleting program files is required when doing a clean reinstall and you may wish to use a clean profile but it is probably best to ensure Profiles are backed up and retained maybe just move the whole profile rather than deleting them because the information is often useful. The profile has your Bookmarks and passwords etc.

Where are you getting Firefox from, you should use the official site for instance
* http://www.mozilla.org/en-US/firefox/all/
Presumably you will be aware that supported Firefox software on Windows is a 32 bit application. That applies even when Windows 64 bit is used, as appears to be the case with the machine you posted from. I mention that in case you have been trying 64 bit builds.
What error messages are you getting ? anything in error logs ?

[SOLVED] Firefox won't open after restart..Until I updated everything

When I start my computer or reboot Firefox won't open unless I keep clicking the icon. I have it pinned to the task bar and it's set as default. when I click the icon it glows orange but then fades back to clear. sometimes as many as 15 - 20 times before it starts. I clean the temporary files every day with CCleaner. I'm not that computer smart but I haven't changed any settings and it was working perfectly until a few days ago. Once it opens I have o problems opening it and closing it
UPDATE:
I disabled the Facebook video call plug in updated all my Firefox stuff and it opened first try

Thank you Alice It took me two years to get Firefox looking exactly how I wanted it. I'm not very good with computers. I thought I would have to start over. The strange thing is there was no indication of a problem. It just wouldn't open. Skype kept crashing my computer so I followed their instructions on removing everything in the registry. I remembered something about Facebook video chat being through Skype so it just made sense to disable it. I didn't even know I had it until I updated the rest of the stuff. I don't know if that was it but Firefox is working and that's what matters.

Can't open firefox, get error message: The instruction at "0x00000000" referenced memory at "0x00000000". The memory could not be read". Firefox won't open at all, not in safe mode or anything. Tried uninstalling and reinstalling, no good, tried creating

Cant' open Firefox at all, not in safe mode either, tried creating new profile, cant' get in to do that, tried uninstalling and reinstalling, switching off and on, nothing works. Get error: "The instruction at "0x00000000" referenced memory at "0x00000000". The memory could not be read."
== This happened ==
Every time Firefox opened
== today. ==
== User Agent ==

The solution is easy.
Install "Malwarebytes' Anti-Malware" free edition and use it. This program found malware in your pc. After that clean this malware. Finally instal Firefox again and enyoy it because this installation is correct and clean. Regards.

Then it just sits there forever, spawning and killing new processes. Firefox never appears.
Any ideas?

In order to test the problem, I think my suggestion is better; at least as a first try. Without Firefox running and without ~/.mozilla; no misconfiguration should prevent Firefox to run. The options you suggest will try to disable any problematic configuration. It can be usefull if you need to start Firefox to fix a configuration problem; but as a firt try renaming the ~/.mozilla is better because you are sure that Firefox can't read anything that can hurt it. Only after having figured out that a bad ~/.mozilla is the cause of the problem, we can try to fix the configuration (or restart with a new configuration).

Firefox won't open a new tab. It opens links on a new tab but if I try to open a new tab manually it does nothing. It was fine yesterday but not today.

That can a problem with the Ask<i></i>.com toolbar (Tools > Add-ons > Extensions)

Thanks for your help. I had tried starting Firefox in safe-mode before I posted this request, but it did not work. I tried to restore the system to an earlier version, but that made everything worse. Two accounts were unusable and one sort of worked, so I reloaded the operating system and now firefox works, for how long, I don't know. But thanks again for your suggestion.

I downloaded Firefox 4 and it won't open unless I open Thunderbird first.

Thank you. I noticed that the file on my computer was not as large as it was supposed to be, so I downloaded it first thing this morning and was able to open and install it. Thanks for the help to all.

After upgrade to mavericks: time machine keeps asking for my back up disk and won't open unless i plug in the disk. any solutions?

after upgrade to mavericks: time machine keeps asking for my back up disk and won't open unless i plug in the disk. any solutions?
before the upgrade, i could open time machine without the need for having the back up disk plugged in.

Ok. I got it to work, sort of....
As I mentioned before I tried the "disk password" and the "Time capsule Password" options to see if I can start the back up again or start a new backup. Neither worked. So I tried the firmware down grade, but like you said that did not work. I then decided to try the "Account password" option and I have never used this option before becasue it states that if there is data on the drive it would not be acessable after creating an account. Since I wiped out the disk that was nno problem. When I created the new account and choose the drive it asked for the user name and password. I entered the info for the new account I just created(FYI this has nothing to do with your login username and password), bingo! It worked!
Now I have two partitions on the TC disk. The old one and now the new account. I am guessing this is to be used if I have multiple computers, which I don't.
I any case, I am going to wipe out everything again and try again to do a backup the way I had it before.

Firefox won't open following update. Can't open Profile Mgr, even when using entire directory path in cmd line

I'm running Firefox on a Windows 7 machine. Firefox won't open following the latest update. I've read the help articles and it seems like I need to create a new profile because my settings have likely been corrupted. I'm unable to open Profile Mgr, even when using entire directory path in cmd line. I've tried the following commands in the command line:
firefox -p
"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -p
Nothing happens with either command.
I'm also running Norton Internet Security. I read a help article Re Virtual Browsing features possibly causing a problem. The article said to check the virtualization setting in the internet security software and to clear the virtual cache. I went thru all of the settings menus in Norton Internet Security version 21.6.0.32 and I didn't see anything that looked like 'virtualization" settings, so I assumed that this doesn't apply to me.
If you have any ideas, I'd sure appreaciate your expertise!!

hello arcandl, when firefox isn't launching after you double-click on the shortcut this is sometimes also a sign of malware being active on a system.
you might want to try running a scan with some different other security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] and [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] which are specialised in removing adware and browser hijackers.

Did you delete the profiles.ini file?
*http://kb.mozillazine.org/profiles.ini_file
You can use this button to go to the currently used Firefox profile folder:
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
*Windows: %AppData%\Mozilla\Firefox\<br>C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\
*Linux: ~/.mozilla/firefox/
*Mac: ~/Library/Application Support/Firefox/
You can use one of these to make Firefox create/use a new default profile:
*Delete the profiles.ini file to force Firefox to create a new default profile
*Use the Profile Manager to create a new profile
*Use "Choose Folder" when you create a new profile to select the location of a lost profile and recover this profile

Updated to 4.0 version and when it loaded I got 4 identical icons on my desktop. I went back in time on my computer and now Firefox won't open.

Updated to 4.0 version and when it finished loading I got 4 identical Firefox icons on my desktop. I went back in time on my computer to go back to an order version and Firefox won't open or is very slow to open.

Do a clean (re-)install:
* Download a fresh Firefox copy and save the file to the desktop.
* Firefox 4.0: http://www.mozilla.com/firefox/all.html
* Firefox 3.6.x: http://www.mozilla.com/en-US/firefox/all-older.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 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.
