Firefox doesn't open when I click the icon

I've tried all the suggestions such as reinstalling, removing profiles, reseting PC. my Chrome and IE also dont open.
Any help is much appriciated...

hello madoded, if no other browsers start either then it might be a problem deep in your system that we cannot address with standard firefox troubleshooting procedures.
however, you can try the following: first please make sure that your security software isn't blocking your browsers. since such issues can also be caused by malware, also run a full scan of your system with the security software already in place and different tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes], [http://www.microsoft.com/security/scanner/default.aspx microsoft safety scanner] & [http://www.kaspersky.com/security-scan kaspersky security scan].

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 suddenly not open when I click the icon, even though I have used Firefox on this computer for several months with no issues.

I have always used Firefox with no problems but suddenly the window will not even open when I click the Firefox icon. No error windows appear either.

Hi pkuhne-
I am not sure why your Firefox stopped working all of a sudden. I would recommend uninstalling and then re-installing Firefox.
1) Get new download: http://www.mozilla.org/en-US/firefox/new/
2) Uninstall your current Firefox version.
3) Do not remove personal data when you uninstall the current version.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
4) 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.
Your bookmarks and other profile data are stored elsewhere in the Firefox Profile 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.
Hope that helps

Firefox will not launch when I click the icon, it worked okay previously

A week ago firefox began taking a long time to launch sometimes requireing reclicking the icon.
Now it will not launch at all.
I get no error messages, nothing happens when I click the icon.
HELP

A possible cause is security software (firewall) that 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 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 doesn't always open when I click the icon

I am running Windows 7, and was running Firefox 6. I just upgraded to 8. Regardless of the version of Firefox, however, there are times when I click the Firefox icon to start it (or try to open from a program list), yet a window doesn't open.
Judging by the task manager, it's actually running - there is just no visible window. Sometimes I can get it to start by "opening" it and ending the process in the task manager a few times, but sometimes I have to completely restart my computer to get Firefox to actually open.

Try to close Firefox via "File > Exit" if you are currently doing that by clicking the close X on the title bar.

Firefox was working, then when I clicked the icon to open, it said it needed to restart to complete a previous installation. After restart, it will not start at all, goes straight to crash report in regular and safe mode.

The only recent changes to the PC are:
Ran latest Microsoft updates.
Installed Halo2, F1 and TinTin games (all purchased from store, installed off original CD)
Installed DirectX
Installed Microsoft Games for Windows Live and reditributable
Installed Visual C++ 2005 redistributable.
Have tried new installation of FF, won't install, repeats dialog about needing to restart to complete a previous installation (see question above)

Why does it take 7-42 minutes for Firefox 4 to open once I click the icon? (I have timed it, yes.)

I'm writing this on ie, which I HATE, because since I installed F4, it will not start up in a reasonable time. I did all the basic troubleshooting, uninstalled and re-installed it, checked the options, etc but nothing works. Everything elso on my computer works instantly, except F4. What's up with that and am I going to have to go back to using the hated ie all the time?

It sounds to me like the installation didn't perform correctly.
What I suggest you do is to go to Add/Remove Programs and uninstall it, but don't checkmark the option to remove your bookmarks, customizations etc.
Before you do that though, go to [http://www.mozilla.com/en-US/firefox/fx/?ref=logo Download Firefox 4.0] and download a fresh installation file.
After you uninstall the existing installation, reboot.
It's also wise to disable your AV before installing again. If you've got AVG, this is particularly difficult because it doesn't have an Exit option. Instead, you have to open MSCONFIG and remove the checkmark from '''AVG Watchdog '''which disables everything. Any changes to MSCONFIG requires a reboot I regret to say.

Firefox window doesn't open when you click the Firefox icon.

I have tried solving the problem with the solution you offered but it still doesn't work.
I cant find those the Virtual Browsing feature in my security software...

Hi,
You can try to access the support forum/online support of the security software. For many of the common configurations please see [https://support.mozilla.org/en-US/kb/Firewalls this].
[http://kb.mozillazine.org/Firewalls AV/Firewalls Configuration]
You may also want to check if Firefox is executable via its icon in the [http://kb.mozillazine.org/Installation_directory installation directory].

Firefox home page doesn't open when I click on Firefox. Have to go to File and click on New Window to get into Start Page.

Firefox doesn't open when I click on it. I have to click on New Window under File to get my bookmarks and a search page
== This happened ==
Every time Firefox opened
== No way to know. Nothing new has been done to Firefox.

If you close Firefox, then start Firefox in Safe Mode, does the problem still occur? For instructions on starting in Safe Mode, see [[Safe Mode]].
BTW, you really should upgrade to the latest version. See [[Updating Firefox]]

Firefox won't open when I click on the icon. I've tried uninstalling so that I can reinstall, but it says I have to close firefox (which isn't open), so I'm stuck.

The problem: Firefox won't open when I click on the program.
Solutions tried: #1) I tried to uninstall the program so that I can download it again, but the screen shows the message "firefox must be clsoed.. to proceed with installation". However, firefox is not open.
#2) I tried to download firefox, thinking that possibly it would update and solve the problem. However, I get the same error message that "firefox must be clsoed.. to proceed with installation" Problem is that firefox is not open.
I've done a screen shot, so you can see that I do not have the firefox browser open.

Thanks for the reply. I tried repairing the permissions (as well as several other things like deleting the Finder preferences file), but no dice.
Given that the problem cropped up right after updating OS X on two separate machines, it's looking to me like it's just a bug that needs squashing at this point.

Firefox does not load up, open up when I click the icon, or when I go to firefox using the start menu.

I downloaded firefox 4 and used it for a few days and then it ceased to open up when I clicked the icon or went through the start menu. I uninstalled and reinstalled it and it still does not open.

Have you tried opening in Safe Mode - Hold down the Shift key as you double click.
Your Ask Toolbar is a known problem.
If Safe Mode works you can work your way through this -

Have you tried: click Firefox button > New Tab > New Window '''''OR''''' CTRL+N '''''OR''''' File > New Window (if using the Menu Bar)
Once open, Firefox locks the Profile that is in use and you can not open another window with that Firefox version and Profile combination using the Windows Desktop icon or the Windows Programs list.
