Firefox won't open/run on extended desktop/multi monitors

Firefox will not boot and run successfully in any extended screen/desktop mode--only when using the local laptop screen itself.
I wiped an older version, but even the installation sequence ran like cold molasses in... Had to drag windows to cause them to refresh, so I could see what options to click. Windows did not appear responsive to mouse clicks. They were, but took minutes to respond.
Finally, I tried a Windows key-P and chose Disconnect Projector--and there was Firefox. But back at extended display, Firefox refuses to run.

Try to disable hardware acceleration.

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.

Firefox only opens on my extended desktop.

I run a smart board in my classroom through my MacBook Pro. When I open Firebok, I can only get Firefox to open on the extended desktop. It will not open on my main screen. The only time i can get Firefox on my main screen is to disable the extended desktop or drag it over to the main desktop.

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:

Firefox won't open/connect tp the internet. Explorer opens and connects. Windows firewall turned off. No other antivirus program running. Happened when I downloaded new Firefox update.

I had the same problem when i dl-ed a new anti-virus softward, but what I did help me reconnect Firefox again!
Here is what I did,
Go to open firefox browser-->option-->advanced-->network-->settings-->and change it to auto-detect proxy settings for this network!
It worked for you, hope it will work for you too =)!

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.

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.

After updating to latest version, Firefox won't open

I am running Windows 7. After updating to the latest version, Firefox won't open. I get a notice when I try to open Firefox saying "Couldn't load XPCOM. Is there a way I can undo the update so I can get Firefox to open. It's my favorite browser...I'm having to use another browser to ask my question.

Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 23: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you lose personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

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.

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 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 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.

Firefox won't open because it says it is already open when it ain't

Firefox won't open because it says it is already open. It appears Firefox is operating in the background. Tried to remove it but we get the same message to log out of Firefox. For 10 years we have been using McAfee with all features but it does not detect any virus or malaware etc. It appears it might be a malaware problem but even using all the latest Microsoft fixes hasn't helped. We used Vista Business Professional with all the latest service packs updated. We use the latest version of Firefox as of up to around 3 weeks or so ago when this issue first appeared.

I suspect you need more expert help but here are a few things you can try.
If you can't open Firefox(double click on Firefox desktop icon) try Safe Mode - Hold down the Shift Key as you double click on the icon>don't check anything on the page that opens>continue. If Firefox opens and works in this safe mode go to Add-ons> Extensions and look for "Ask". Then look at Add-ons >Plug-ins and again look for "Ask" . Remove, delete,disable any Asks. If you do remove any, close Firefox. And try again in Normal Mode.
The Ask website has detailed instructions for removal but you need to find it on your computer and have your computer in working order.
If there is no sign of Ask and Firefox is working well in Safe Mode you should work your way through this -
https://support.mozilla.com/en-US/kb/Troubleshooting%20extensions%20and%20themes
Eventually you might need to grapple with About:Config and even your Windows Registry but I would recommend a complete uninstall and re-install before that. Unfortunately that often doesn't work.
That all sounds very daunting but taken step-by-step you might get lucky early.

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

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!
