A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, maybe 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.

Firefox shows in task manager, but won't open

Firefox doesn't open, though it opens once in a while. It shows in task manager and takes up 50% CPU usage, and ending process and retrying doesn't work. Profile manager doesn't open either. There's no error message, and have restarted laptop (Windows XP) many times, but no results.
Help would be appreciated!

Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#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).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#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.

ITunes shows in Task Manager but doesn't run

I was having an issue where my iTunes would start and show as a process running in Windows Task Manager, however, the GUI interface would never show up. I could end the process, but restarting the application led me to the sam state I was in before; the process was there, but no iTunes.
I am running Windows XP Media Centre 2005 edition with rollup 2, 2Gb of RAM, AVG AntiVirus, all the latest MS patches and Windows Defender all up-to-date. Stopping all the anti virus and anti-malware programs didn't help. Reinstalling iTunes did nothing, and installing the stand-alone version of QuickTime did not work either.
I searched many an archived article to find the particular solution that worked for me, and I have linked to it below.

Hope this helps someone in the future. It was a very frustrating exercise, to say the least.

Firefox won't start, no error message, firefox.exe showing in Task Manager Processes

Firefox (v3.6.6 on Windows Vista) will not open. When the icon is clicked, the hourglass shows for a few seconds, goes away, and nothing else happens. There are no error messages. 'firefox.exe' shows on the Task Managers Processes tab. I also cannot open Firefox in SafeMode or with the ProfileManager.
I have tried restarting the computer, uninstalling and reinstalling firefox, deleting my firefox profile. I have tried all of these things multiple times in different orders with no results.
Please Help!

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!

FF shows on the task bar shows running on task manager but I can not maximize it

FF shows on the task bar shows running on task manager but I can not maximize it.

Can you try starting Firefox in Safe Mode. To do that, hold down SHIFT while you click the desktop shortcut or quick launch icon. Then click the '''Continue without making changes''' button.
If it works in that configuration, then one of your add-ons is the culprit.

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 starts, process shows in task manager, GUI doesn't appear.

Well I just installed windows 7 pro 64 bit. Installed firefox 3.6.13. Worked fine (Using my 8years old profile). Then in mean time SP1 finished installing. After reboot firefox doesn't work. Nor the profile manager (firefox -p) nor the safe mode (firefox -s) nor normal mode. All those make firefox process show up in task manager, but no GUI. Same goes for firefox 4 beta. All versions of 3.6.4 up (so all versions with plugin container) and 4 beta I can find and download behave the same. Even some 3.7 alpha 5 thingy. Only version that works without troubles is 3.5.x and 3.6 up to 3.6.3 I'm on atm. I totally don't get it why its happening. Same profile with 3.6.4+ and 4 beta works fine on my sis laptop on same windows, with same updates. Actually first time it happened was on 32bit version of windows 7 pro. Firefox 3.6.11 (there weren't any newer version out yet) just stopped to work with issues like above described after one of windows updates. Cant pin point which one now cuz it was months ago. My rig is E8200, 6GB DDR2 1066cl5 ram, Gigabyte Ep45-Ds3r, ati 4850. I cant point anything else than just some windows 7 pro update, hardware and plugin container incompatibility. 1 in a million chance that makes this happen and of course I'm the happy winner of firefox issues ^_^. For people asking to switch of plugins and testing other profile. If I downgrade to 3.5 or 3.6.3 change profile to naked new one, then upgrade to 3.6.4+ or 4 beta, and exactly same stuff happens: no GUI, firefox process in tasks with 10-20 threads, and 7-30MB loaded into memory (depending on version, mode used).

Well I write once again. This time I have solution to my problem. Its HDTunePro 4.5. I admit I do have an not so legit version, and it seems its loaded with some crap, or the HDTunePro itself is. Thing is, after reinstalling whole OS (Win 7 Pro 64bit). With everything: drivers, games, programs. Everything worked, ACDSee, FF4.0, and so on. Then after installing HDTune - magic: FF, ACDSee stopped to work the same way it was before. In a process of finding out what exactly is at fault here (cuz I did install few windows updates with HDTune) I found few things: First, installing that HDTune from its install file, makes FF, ACDSee not work (the loading issue with programs stuck in task manager). But whats funny HDTune itself have the same issue (15 day trial - doesnt boot up more than process in task manager). Patching it with that not so legit thingy makes HDTune work, but all other stuff not. So solution is simple, not using HDTune Pro, at least 4.5 non legit version (HAHA theres a lesson here to not pirate software). Or do a work around - make system restore point, install HDTune, patch it, change extension of exe file (so it will not be *.exe), restore OS to that restore point, change exe extension back to *.exe, done. After this HDTune and all other stuff works.

I have windows 7 and my firefox client will not open, but it shows in task manager with 108k memory. Whats going on with my firefox?

As stated on the question I have windows 7 and meet all the requirements. But when i launch firefox It wont start, but it shows in task manager with 108k memory.

Got the exact same problem aswell, finally fed up with it now as i just started up firefox and 14 new windows opened because of this bug, luckily my computer can handle them but someone with a slower processor it would have been a nightmare, needs fixing ASAP.
Reverting back to 3.6.3 until this issue is solved. (link for anyone wanting to do the same below)

Multiple instances of firefox in task manager but FF doesn't open

- Windows XP SP3 (up to date with all critical updates)
- FireFox 25.0.1 (Note: Originally I had version 31 but a few days ago that stopped working)
- Norton Security Suite (the comcast version) up to date
- I have IE6 and Chrome 37 as backup browsers (Note: when FF stopped working, IE8 had also stopped working - page would open, only one system process, but page would never load)
Ran the following scans:
- SUPERAntiSpyware Free Edition
- Malwarebytes Anti-Malware
- Ad-Aware Antivirus
- Spybot-S&D Start Center
Found a few non-critical yet potential infections (nothing too crazy)
Symptom persists as follows:
- fresh boot of computer
- open task manager (no instances of FF)
- open firefox - process appears in task manager and immediately goes to 50%
(nothing opens and nothing listed in Applications)
- open a second instance of firefox - 2nd process appears in task manager
(still nothing opens and neither instance appears in Applications
(the two instances continue to run at a cumulative 50% CPU usage - one might be 15% and the other running at 35% - or both running at 25% each)
- open a third instance of firefox
(still nothing opens, and all three instances show in task manager processes and cumulatively run at 50% - example:15 +15 + 20 or 10 + 15 + 25)
Troubleshooting:
restored a drive image from May 2014
- Note: Dec 2013 I had done a complete FRESH new install of Windows XP in prep for EOL and installed all updates, including SP3, so the image I chose from May was only 5 months old, but I chose that one because of some of the other programs I had installed that month and didn't want to go through that again
- Note #2: I have drive image run a monthly PQI backup of my C: drive and my R: drive) I have two hard drives 300G each whereas C: drive is OS only and R: drive is all my downloads, my documents, my photos, etc)
- after the image restored, I tried to open FF and IE8, neither app was problematic. FF auto updated from what version, I don't know, but it was on 31 when I realized the problem was BACK. Also ran some WIN critical updates, and IE8 stopped working too!
uninstalled IE8 (rolled back to IE6 and now IE works - but obviously I can not live with IE6 - I need to update that!) uninstalled FF31 (and deleted all temp and profile account folders) and installed a brand new copy of FF25 - whereas I immediately force stopped autoupdater and deleted the update files so I could remain on FF25.
Now FF25 will open only on the second instance of the process (the first will always go to 50% CPU, the second will open and run between 0 and 10 CPU, and only one application in Applications)
- I have learned that I can kill the 50% process using task manager or process explorer and total CPU usage will drop down to 0% - 10%
I can open many many tabs without any problems, and I can right click a link to open a new window and all is good, BUT if I use the desktop ICON, the quick launch ICON or the START > Programs > Icon, then the NEXT process will go to 50% and no second window will open
I have seen dozens of forums that have reported similar memory issues, but none have been resolved.
Can you help me? I don't want to upgrade IE6 to IE8 just yet, but I will not use it for anything but testing until I can upgrade. Note: besides being painfully slow, I have been switching to Chrome, but I have never enjoyed Chrome.... I am using FF right now to ask for help.
Any suggestions?

I have the "techie" answer for all of you. According to the tier 2 support at Norton Help Desk, the latest live update from Norton "utilizes Visual Studio 2012 which enables SSE2 instructions" and my processor can not handle that.
He said they are "working on a solution" and offered to reply back on Wednesday / Thursday this week if a solution could be found...

Firefox opens in task manager but does not display.

This morning my Firefox stopped working and I had to end task. Afterwards when trying to restart Firefox the firefox process will open under task manager but nothing displays on the screen. I've tried ending all firefox processes and restarting my pc. I also tried creating a new profile under the firefox,exe -manageprofile command. When I created the new profile and ran under it I had the exact same problem. I tried running under safe mode and I get the pop up telling me that mozila is running under safe mode with the check box's for clearing settings but there is still no window displayed and when clicking continue in safe mode the pop up box goes away and I'm left with nothing once again. I tried running the firefox setup freshly downloaded in an attempt to repair the setup of sorts but this had no effect.
I also did a short search of the forum for any soloutions but so far haven't found anything. If anyone could suggest some more things to try before I do a complete wipe of Firefox using CCleaner.
Also in the event I use CCleaner I'd like to back up my bookmarks first so if anyone knows a start parameter to back up bookmarks or even what file the bookmarks are stored (already found a forum topic on the saved passwords file) in and if copying that file into a new installation will work please let me know.
Regards to any one who can assist.

I had this problem for a couple weeks as well and it was extremely frustrating considering we use firefox for all our company tasks. Here is the solution:
First of all if you have no bookmarks you want to save, then go directly to step 7. If you want to save your bookmarks first, then follow these steps.
1. Shut down the computer
2. Reboot and open firefox
3. Go to Task Manager, right click firefox.exe, and click END PROCESS TREE
4. WAIT 30 SECONDS! Then Double-click the shortcut to try and open firefox again
5.Repeat steps 3 and 4 until firefox finally opens (trust me, eventually it will)
6. Once it finally opens, backup your bookmarks,
7. Download a copy of firefox from there website
8. Uninstall from programs menu and make sure to check the box REMOVE ALL COMPONENTS
9. install the new copy and BOOM! it works
If it doesn't work, you're an idiot. If you don't want to reinstall firefox, then you're out of luck. Good Luck!

To find lost bookmarks your help says to click on empty space on toolbar to get task manager, but when I click on empty space I don't get task manager.

when i installed latest version of firefox my home page went away and also I lost my bookmarks. Now when I click on the bookmarks tab I get yahoo. I tried your help and it says to click on empty space on toolbar to get to task manager, but I've clicked on all the empty space and no task manager comes up. How do I recover my lost bookmarks?????

This can be caused by a problem with the file places.sqlite that stores the bookmarks and the history.

James,
Thank you for the information. I did what you said but it is still not working. My apple box works with my wifi so I think the wife was disconnected and I can't figure out where to go to set up the wifi pass word for the apple box. Any hits would be appreciated if not my next step is to ship back the box to apple.
Thanks,

Firefox will not launch, but shows in task manager, after updating graphics drivers to AMD's 13.1.

Hi,
After updating to the AMD 13.1 drivers, on my 5770, Firefox will not launch; it does, however, show in the task manager. I should note that it will start in Windows safe mode; when I had it open in safe mode, I used that time to disable all plugins, add-ons, extensions, and created a new profile. This did not help. I also tried launching Firefox in to its safe mode, and had no luck with this either.
I experienced this problem once before, when trying to update to a previous version. I believe I was moving from 12.1 to 12.4, but I'm not 100% sure of that. Ultimately, my solution then was to retrograde back to my previous driver. The steps mentioned in the previous paragraph did not help at that time, not did a complete reinstall.
15 years of computer repair experience, and this has me baffled.
Thank you to anyone who might be able to help.
Possibly relevant specs.
Windows 7 Ultimate x64
AMD Phenom II x4
6BG Ram
AMD 5770 graphics, running Catalyst 13.1

By any chance, did you disable Firefox's use of hardware graphics acceleration? To avoid a round-trip through Windows Safe Mode, you could try adding these to your prefs.js file while Firefox is closed.
To quickly open the folder with the correct prefs.js file, you can use
Help > Troubleshooting Information > "Show Folder" button
Because Firefox may overwrite change to this file at shutdown, you should edit it after closing Firefox and allowing a few moments for Firefox to finish updates to the files.
These are the preferences I think are most relevant:
user_pref("gfx.content.azure.enabled", false);
user_pref("gfx.direct2d.disabled", true);
Does that make any difference?

I run firefox, it shows in task manager, but nothing on screen, i run it again get it on screen but nothing happens its dead
