Firefox won't start on first click

Everytime I try to open Firefox by simply double clicking on it, it won't work. In order to make it open I double click on it many times. I always get a couple of Firefox windows but not the exact same quantity as the times I double clicked on it. Help please.

Hello,
Your Firefox profile may have an issue that is preventing Firefox from opening as quickly as it has before.
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your bookmarks, history, passwords, cookies, and other essential information.
'''''Note:''' After resetting Firefox, you will lose any extensions, toolbar customizations, and some preferences.'' See the [[Reset Firefox – easily fix most problems]] article for more information.
To Reset Firefox:
# Open the Troubleshooting Information page using one of these methods:
#*Click the menu button [[Image:New Fx Menu]], click help [[Image:Help-29]] and select ''Troubleshooting Information''. A new tab containing your troubleshooting information should open.
#*If you're unable to access the Help menu, type '''about:support''' in your address bar to bring up the Troubleshooting Information page.
#At the top right corner of the page, you should see a button that says "Reset Firefox" that looks like this: [[Image:Button reset]]. Click on it.
#Firefox will close and reset. After it is done, Firefox will show a window with the information that is imported.
#Click Finish and Firefox will reopen.
Did this fix the problem? Please report back to us!
Thank you.

*Help > Restart with Add-ons Disabled
Another possible cause is security software (firewall,anti-virus) 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 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 on first click. I have a Windows 7 PC.

With both the last version and this new Firefox 8, Firefox will not open on the first click on the taskbar, second, third, fourth, or when I click on the desktop icon. It suddenly opens after about the 7th click and I get 5 to 7 start pages. It used to open after the one click on the icon on the taskbar. I have a Windows 7 PC.

Firefox won't start when double-clicked or when clicked on from the Start menu - but other programs say it IS running.

When I go to the START Menu to start up Firefox - *or* double-click the Firefox icon on the desktop - the program will *not* start. Yet if I try to do something that may interfere with Firefox, it says to close Firefox down because it's running.... which it isn't. Even going into the Task Manager through *control-alt-delete* shows plainly that Firefox is not running... I downloaded a game through Mediabox.com to watch a movie, that may have started the problem.

No - I get the message basically saying "Can't run program while Firefox is running. Please close down Firefox & try again".
I rebooted my computer and it all works now - but that's weird it was happening before. Kinda weirded out that it happened at all.
To avoid that happening again, I still wanna know what to do to avoid it or fix it for next time. Thanks

HI I have a problem with my Firefox, recently my fire fox won't start after I click on its Icon

Exe in "target" as shown in the following picture, then press "Ok" 3- Open Firefox, and then choose "options" from the list of "tools" 4- Select the tab "general", and in the list "when Firefox starts" then select "show my homepage" and in the box "homepage" then enter any other link and then press "OK"

Firefox won't start. Everytime I end the process/close the last window, it keeps getting stuck at about 2500k memory in the task manager. (continued)

Firefox won't start. Everytime I end the process/close the last window, it keeps getting stuck at about 2500k memory in the task manager. The only way I have to fix it is to change some kind of compability settings or try and access it in a new way, and every time it crashes/closed/computer blue screens that setting will no longer work.
That is a short term solution, but eventually I'll run out of ways to access firefox successfully. I've tried many solutions, and some worked, but only once. I have yet to find a permanent solution for this problem.

First please update your plugins to make sure you are up to date. Shockwave Flash player has a newer version 16. In order to better manage the memory that Firefox uses please see these troubleshooting steps: [https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-ram Firefox Uses too much RAM]
You also mentioned that Firefox crashes, we're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.
#Enter ''about:crashes'' in the Firefox address bar and press Enter. A Submitted Crash Reports list will appear, similar to the one shown below.
#Copy the '''5''' most recent Report IDs that start with '''bp-''' and then go back to your forum question and paste those IDs into the "Post a Reply" box.
''' Note:''' If a recent Report ID does not start with '''bp-''' click on it and select '''Submit'''.
(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)

Firefox won't start, there is no error message and it is not already running.

Hi,
When I try to click on firefox, the little wait icon appears and then disappears. Nothing opens, not even safe mode. I've looked at the "Firefox won't start and there is no error message" help section and looked at my task manager processes. It seems that when I click firefox, it briefly appears on my processes and then disappears. This happened yesterday while I was in the middle of using it. At the same time, my Skype also crashed, which makes me think the two are correlated. The two programs still don't work. The only way that I can open firefox is if I install it all over again with the "launch firefox now" option checked at the end. When I have a firefox window open, I can open other firefox windows just fine. When I close it, nothing opens. Thanks for your help.

1) Start Task Manager
2) Open Processes (make the description area large enough to see)
3) look for a description that says ''firefox''
4) Select it and press End Process
'''Now Firefox should work properly.'''

Firefox update failed, so I re-installed. Now firefox won't start up at all?

''locking as a duplicate of https://support.mozilla.org/en-US/questions/969557''
So I ran firefox, and it was updating. While updating, firefox crashed for no apparent reason so I had to close it. Afterwards, every time I tried to start up firefox, it gave me the update failed error, followed by a crash less than a second later. I followed some instructions, uninstalling and re-installing firefox (without removing personal data), but now firefox won't start up at all!
Now what?

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 won't start (not even in Safe Mode) on Windows 7 x64

I am Running Windows 7 x64 and Firefox 3.6.15.
Since the day before yesterday I am unable to start Firefox. Even in Safe Mode it just won't start.
I click the Firefox icon, the mouse cursor changes to indicate the computer is doing something. After 3 seconds or so the mouse cursor again changes back to its default state. Nothing else happens.
The Task Manager in Windows shows me that an instance of firefox.exe is running, but I see no Firefox window.
Then if I again click to open Firefox, another firefox.exe instance starts, but again I see no Firefox window.
There isn't even a warning about one instance of Firefox already running.
What I have tried:
I have uninstalled Firefox, removed all the Firefox files and folders from c:\users\username\AppData\Local and Roamning. I re-downloaded the 3.6.15 installation package and re-installed.
No change.

I have the same problem.
The only Firefox version working is the 64bit nightly build 6.0a1. No 32Bit version of Firefox works!. Chrome, Safari and Internet Explorer all work well.
Another Problem I have in this context is, that the Firefox Installer hangs in the tidy up step - even for the nightly 64Bit version. I have to kill the setup.exe process but the Installation seems to be completed.
Before my change to Win7 64Bit I had OpenText NFS Solo 14 installed on a 32Bit Windows7 and no Problems.
Is there a solution for this problem without uninstalling OpenText NFS Solo 14?
I need the NFS Server at work.

Firefox won't start; no error message; profile manager also won't start. What can I do?

Suddenly, firefox won't start. I get no error message--it just won't open. System restore to a month before the problem did not help.
From the suggestions on this page: http://support.mozilla.com/en-US/kb/Firefox%20will%20not%20start... I did not recently install add-ons or clean the registry, so I think it may be a profile problem. But profile manager will not open--only a tiny window with a white rectangle and no text.
I would like to not lose all my bookmarks. And I would like to continue using Firefox.
What can I do?

dmcritchie, thank you for your reply!
Before I received your response, I tried something that seems to have worked. I used Chrome to go to the Firefox website and downloaded Firefox (without uninstalling it first) and went through the installation process again. For some reason, this worked, even though I already had the latest version of Firefox, and I can now open Firefox successfully.
If it stops working again, I will try your suggestion. In the meantime, thank you much!

Firefox won't start after windows update

After windows Updated my computer Firefox won't start. I tried a clean reinstall two times, won't work. When I tried to start the firefox the first time after booting my computer it comes with the following message.

I do not see much about coloum 14, but I am guessing this file is stored somewhere and its corrupt. Update.xul suggests that it is the update file. Do you still have this in your downloads folder? There are two places for update and for a clean reinstall:
[http://www.mozilla.org/en-US/firefox/new/] in a private window will give you a new install or you can choose from here: [https://www.mozilla.org/en-US/firefox/all/]
This is what the file should look like; [http://hg.mozilla.org/mozilla-central/log/7a2edc5171e6/toolkit/mozapps/extensions/content/update.xul] If you can copy and paste that file from a working browser we can see the issue, but it will just look the same as the error.
if you can replace the contents of the file locally with what it should look like it will fix the error, but who knows if there are other errors. May be best to delete the updater and save all the profile folder contents.

After reboot firefox won't start. runs in task manager, but won't pop up. reset, safe mode and uninstall/re-install won't help. ok if no reboot.

win7 Pro. has been running firefox ok. but lately with 25 and now 26, the firefox won't start. I can see firefox is running in task manager. but it just won't pop up.
if I download it again and install it, it will run, but every time I reboot the system, it just won't run again.
try: reset, safe mode, uninstall & reinstall, new/clean profile, none of those work.

There may be a corrupted file on Firefox.<br>
Please attempt to perform a clean reinstall. <sup>[https://support.mozilla.org/en-US/kb/forum-response-clean-reinstall (More Details)]</sup> This is different than a regular uninstall.
If a clean reinstall does not fix the issue, please try starting your operating system in safe mode.<br>
To do so, please do the following:
#Ensure that your computer is shut down completely
#Press the power button
#Tap the <code>F8</code> key repeatedly before the Windows logo and startup screen is displayed
#Select Safe Mode With Networking for the advanced startup options list
Please report back with the results of both solutions.

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 won't start after an update. Firefox help says check virtualization settings. What is virtualization settings and where do you check them and for what? I have Windows XP

Firefox won't start after downloading update. I've reinstalled Firefox, still won't start. Help says check virtualization settings. What and where are virtualization settings? I have Windows XP.

This might be Zone Alarm since it provides virtualization. Please try the instructions to turn off virtualization in the following support question

Firefox won't start on windows 7. Used to word when it was on version 18. I have different windows 7 machine it works fine on that.
