Firefox won't open until Task Manager is opened, why?

Recently I have noticed a slight problem with my Firefox browser. Upon closing when I attempt to re open (shortcut: ctrl + alt + f), it just sits there. It doesn't even appear to be registering that its trying to open. If I try to open again it does nothing & will only fully open & show the running Firefox windows when I open Task Manager. It doesn't happen all the time although its been an off & on occurrence over the past few days now. Is this happening because of the shortcut key? Or is there another problem why it wont start until Task Manager is opened?

[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.

Firefox won't open when prompted the first time. Says "Not Responding". I have to hit cntrl/alt/del then try starting again. Sometimes multiple times.

Sounds like a "hang at exit" problem. There are several possible causes for that error. See:
* How to stop the running Firefox process
** In Task Manager, does firefox.exe show in the '''Processes''' tab?
** See: http://kb.mozillazine.org/Kill_application
* What may cause Firefox to hang at exit
** http://support.mozilla.com/en-US/kb/Firefox+hangs (see "Hang at exit" section)
** http://kb.mozillazine.org/Firefox_hangs
** https://support.mozilla.com/en-US/kb/Firefox+is+already+running+but+is+not+responding
* You may need to try Firefox Safe Mode
** You may need to use '''Safe Mode''' to locate the problem: http://support.mozilla.com/en-US/kb/Safe+Mode
**Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes '''before''' starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
** If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it by enabling '''one at a time''' until the problem reappears. '''You MUST close and restart Firefox after EACH change''' via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.

Firefox won't open on WIndows vista & it has worked for years.

Used task manager, closed firefox.exe & restarted, worked twice & I disabled Norton Toolbar. Now firefox won't open. I uninstalled firefox and redownloaded it & still won't open. Search for the Profile Manager doesn't show anything.
I did download an HP update yesterday. I am using windows explorer for this since I have toahve that on my computer to access some citrix programs

Right mouse click the iTunes icon and select "Run as Administrator"

Firefox won't open...error message - "your firefox profile cannot be loaded. . It may be missing or inaccessible." Please help. I have unistalled & reinstalle

Firefox won't open for me. I keep getting the errors listed below:
"your firefox profile cannot be loaded. . It may be missing or inaccessible."
"Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."
Nothing is running. I've killed all the firefox processes, restarted, uninstalled and reinstalled.
What can I do?
Thanks

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\ 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

Firefox won't open, says profile may be missing or inaccessable, help pages not helpful

Firefox won't open at all. I get a "Profile Missing" window saying "it may be missing or inaccessable". This morning my connection quit mid-reset while it said it was going through everything and not to turn it off, since then it refuses to open. I tried everything I could think of. Tonight I managed to open an ancient IE and am here now, tried as much of the "Help Pages" suggestions as the site sent me to (none were what my computer has even though I'm running XP), but nothing fixed the problem. I removed Firefox and then re-installed, twice, it still won't open.
HELP!

I can find NO "profiles.ini" file anywhere. When I open the "default library" there are none of the files you say should be there.
I have tried a whole new download to update, it won't open because there is no profile.
I tried removing the program and re-downloading, still won't open.
I am not tech savvy enough to do much of the messing around you are suggesting. I need someone to help!
Also - this site is about the least "user friendly" site I've had to deal with in ages!
I should have been able to reply to the email, but you didn't allow that, too.
I need someone to somehow walk me through what to do. HELP!

Firefox won't open from the taskbar or desktop - what do I do

Firefox won't open. I uninstalled it and downloaded a new one. When I tried running it I was asked to close Firefox. As I did not have it running, I could't close it. All other programmes were closed. I also have the mozilla email which is still working.

Hello Gigi,
Thank you for providing so much detail about the issue you are experiencing with the iTunes app after upgrading to iOS 7.
The first thing I recommend is quitting and relaunching the applications on your iPhone:
Double-click the Home button.
Swipe left or right until you have located the app you wish to close.
Swipe the app up to close it.
You can find the full article here:
iOS: Force an app to close
http://support.apple.com/kb/ht5137
If you are still seeing the same issue after quitting and relaunching the iTunes app, I recommend restarting your phone and then resetting if it's still not working:
Restarting your device
Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider.
Press and hold the Sleep/Wake button until the Apple logo appears.
Note: Reset your device only if you are unable to restart it.
Resetting your device
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
You can find the full article here:
iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting
http://support.apple.com/kb/ht1430
If the issue persists, the last thing I recommend is backing up and restoring your iPhone:

I changed my setting to private browsing and now firefox won't open. Any ideas?

I changed my setting to private browsing and now firefox won't open. Any ideas?

In what way did it not open? Was the Firefox icon on the task bar?
Did you get any error messages? Did the computer show Firefox
as running?

Am told firefox is already running , but task manager doesn't show it

am told firefox is already running , but task manager doesn't show it. I installed Firefox 3.6.10 on a new computer (win 7 home premium), deleted the profile given and copied my old profile in its place (win vista premium). I get the above message and am told to close the existing process, or restart the system. Can't close and restarting doesn't help. Please solve this for me, i so don't want to use Internet Explorer

g'day people... a dude called "moopenguin32" showed me the way... alleluia
1. Copy your Firefox shortcut (what you click on to open Firefox) to the Desktop.
2. Right-click on it and click on Properties.
3. Go to the end of the text in the "Target" field. The end will say: firefox.exe"
4. Enter a space followed by: -profilemanager
5. The end result will look something like this: "C:\Program Files\Mozilla Firefox\firefox.exe" -profilemanager
6. Click OK to save the settings.
7. Double-click on the shortcut you just changed.
8. Delete the profile listed. It shouldn't matter that you're deleting it because you're trying to restore a profile anyways. You should have the profile you're trying to restore saved elsewhere.
9. Close the profile manager.
10. Start Firefox using your regular shortcut. Firefox should open properly. Close Firefox.
11. Now to restore your profile, open the profile folder you have backed up and copy the contents of it rather than the actual folder.
12. Go to your existing Firefox profile and open it.
13. Delete the contents of the existing Firefox profile.
14. Paste the contents of the Firefox profile that you're trying to restore (the one you copied in step 11).
15. Open Firefox and everything should be there (including your extensions).

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.

Tried to use Restore to return to pre-Firefox4 but now Firefox won't open and won't uninstall.

After trying to maneuver the new Firefox 4.0 for a while and giving up, I wanted to go back to the 3.6.1.6 version. I used the Restore feature to try to go back to the pre-Firefox 4.0 dowload. Since then, Firefox won't open. I have tried to uninstall Firefox 3.6.1.6, which is listed in my installed programs in the Control Panel, but it doesn't do anything. At this point I don't know what to do. I want to re-instate the 3.6.1.6 version on my computer. Thanks.

You're in a bit of a pickle here because you can't use System Restore to revert to 3.6.16. You probably now have version 1.9.2.x which is in part, files which were not removed when you installed FF4
What you can try and do is use System Resore to undo the last restoration which should take you back to 4.0 again. If that fails, see this article: http://kb.mozillazine.org/Uninstalling_firefox
If the undo restoration is successful, do the following to revert to 3.6.16
Go to [http://www.mozilla.com/en-US/firefox/all-older.html Download Firefox v3.6.16] and download it to the desktop. If necessary, download the file with IE8 and choose to save it to your desktop when you see the prompt.
Then go to Add/Remove Programs, scroll down to Mozilla Firefox and remove it, choosing to keep your bookmarks, customizations etc., (don't checkmark the box).
Then reboot and delete the folder called '''Mozilla Firefox''' at this location: ''C:\Program Files\Mozilla Firefox''
Finally run the installation file you downloaded to the desktop earlier.
Your bookmarks, customizations etc., are maintained in a different location and will become available to you again once you complete the installation.

Firefox won't open links from Mac Mail

Like everyone else Apple Mail links will not open in Firefox if it is already open. Clicking a link brings FF to the front but no page loads. Links work if FF is not open. Links work if command is pressed whilst clicking the link (opens in new tab in background).
Problem occurred after 32.0.2 update, it appeared to briefly resolve itself after 32.0.3 update, but stopped (I think) on next reboot.
Have monkeyed around for ages with different combinations of default browser and rebooting.
Will abandon FF and go back to Safari if this isn't sorted soon - shame.

I just want to link to these earlier threads so you don't get a lot of duplicate suggestions that have already been covered there:
* [https://support.mozilla.org/questions/1018542 Firefox won't open email links after update to version 32]
* [https://support.mozilla.org/questions/1023202 No tab opens when I click on a link if any Firefox window is already open]
(There might be others, but those are the ones I've seen)
Work is proceeding on [https://bugzilla.mozilla.org/show_bug.cgi?id=1017595 Bug #1017595 – Links from external applications sometimes fail to open when Firefox is hidden] but as you can tell from the title, this is focused on the problem of Firefox not coming out of hiding from the dock or coming out of hiding but not loading the page. If this also occurs when Firefox is not hidden at all, there may be a secondary issue. But hopefully solving the one will solve the other. Unfortunately, I don't know whether it will be in time for Firefox 33.

Mac won't open pages in browsers. Chrome and Firefox won't open any pages - Safari will only open a selected few.

I've had some strange browser issues, with Conduit being added to Chrome (which I've tried to remove via the browser settings). Chrome will open my Gmail account but no ther pages. Firefox won't open anything. Safari opens a few pages (this forum thankfully) but is very selective.
Google is returning results to me via Google.es rather than Google.co.uk
I can use all browsers freely on other devices on home network (although Google.es has popped up on my iPhone now). I've run anti-virus software which hasn't picked up any problems. I've tried uninstalling Chrome and Firefox, but am unable to do so.
Any help or guidance would be really, really appreciated.
I'm running the most recent version of Mavericks on 2012 iMac.

Hi,
First of all click Safari/Reset Safari, next click Safari/Preferences/Extensions and turn off extensions. The re-test
If the problem persists, try using safari in safe mode:

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).
