Firefox won't open in Windows 7 Ultimate.

I recently switched to a new computer with a Windows 7 Ultimate 64-bit OS. I set up an internet connection and IE worked fine. I went to download Firefox and the installation went through without a problem. At the end of the installation I checked the box to start firefox and nothing happened. I went to the icon on my desktop, double clicked, same thing. I changed the compatibility and I tried starting it in safe mode, same result. When I click on it, a process pops up in Task Manager for a second and then it goes away. The process has a *32 at the end of it though which is something I've never seen before. I've uninstalled and reinstalled and rebooted countless times, and nothing's worked. I tried renaming the folder in Program Files from "Mozilla Firefox" to just "Mozilla" and that didn't work either. Help!

I removed opentext nfs solo v14 (hummingbird) it is just worked.

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"

I used Computer Associates ver.7.0.0.117 to clear temp files and cache. Firefox won't open a window since though it shows in processes.

System: Toshiba Portege M750, Vista 32-bit SP2,4GB RAM
I've been using Firefox up until last night when I shut down. This morning I did a cache cleaning using CA Internet Security Suite, ver 7.0.0.117. Firefox will not open a window, though it does show in the Processes list of Task Manager.
I've uninstalled and reinstalled ver 6 from the web twice with the same results.
Firefox has had a tendency to hang (never finding a new website, i.e. busy icon revolves endlessly) when left open over several hybernation cycles.

'''Kill Application'''
In Task Manager, does '''firefox.exe''' show in the '''Processes''' tab?
See: '''[http://kb.mozillazine.org/Kill_application Kill Application]'''
'''Causes and solutions for Firefox hanging at exit:'''
'''[[Firefox hangs]]'''
'''[http://kb.mozillazine.org/Firefox_hangs#Hang_at_exit Firefox hangs at exit (Mozillazine article)]'''
'''[[Firefox is already running but is not responding]]'''
'''Safe Mode'''
You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox SafeMode 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.
See:
'''[[Troubleshooting extensions and themes]]'''
'''[[Troubleshooting plugins]]'''
'''[[Basic Troubleshooting]]'''
If the problem does not occur in Safe-mode then disable all of your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You have to 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 new windows or upload video

Firefox is starting to get on my nerves with this one. The program will be working fine and then suddenly stop opening new windows. For example, I'll take a quiz and want to upload my results to facebook. I'll click the button and instead of opening a new window for facebook, it does nothing. Another example: I'm taking an online course and if I click to upload a file, instead of opening a window, it does nothing. When I click the red X to close firefox, nothing happens. Also, the minimize, restore, and close window buttons no longer respond. I have to open my task manager and manually stop the process. I notice when I reopen the program, it offers to restore all of my tabs as well as windows that mysteriously never opened before. This has been going on for about a week now and it really is annoying. I also notice when this happens that firefox seems to be taking up an unusual amount of RAM on my computer. What gives?
I am using the most recent version of Firefox on a Dell PC and running the most recent version of Windows 7.

Hi JuMaGa86,
Thank you for your question. This sounds like a performance issue, please try these troubleshooting steps [[Firefox uses too much memory (RAM) - How to fix]]
Then clear your cache and run the browser for a while to see if the performance improves. We look forward to your reply!

Firefox won't open new windows as maximized

I'm running Firefox 31 on Windows 7, and in the program properties I've set it to run "maximized". When I open a new browser window using either the desktop or start menu shortcuts or "File > New Window" in the browser itself, it opens maximized just as it should. However, when I click a link that's programmed to open in a new window, the new window consistently opens as "normal window" rather than "maximized". I find this incredibly irritating.
This problem did not occur at all back when I was using Firefox 28.
I have not been able to find any way to correct it in the settings or options, nor have I been able to find any remedies in the form of add-ons. Does anyone know how to fix this?

Well that looks easy enough.
Will toolbar customizations be the ''only'' thing I'll lose if I delete my localstore?

Firefox won't open in Windows 8.1 after latest update failed to install

Latest update for firefox failed to install.
Now, when I try to open firefox, I get the hourglass circle and then....Nothing. Check the processes and it is showing as a background process, but not doing anything. No error message, no crash alert.
So, I uninstalled firefox. Download the installer. Open the installer and...nothing. Again the process is there but nothing is happening.
Tried killing all processes and rebooting and trying the re-install. Still nothing.
The only thing I haven't checked is Nortons Firewall but I thought I might as well ask while I am at work if there is anything else I should check.
Was working fine until this update failed. On Win8.1

I would try restoring preferences: Restore preferences | Dreamweaver CS4, CS5, CS5.5
If that doesn't work, a Clean and Reinstall might do it...
Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6

Firefox won't open new windows when I click "File" and "New Window". can you help me?

My question is just as it reads above. My computer is windows 7. I've never run into this before.

This issue can be caused by an extension that isn't working properly.
Start Firefox in [[Safe Mode]] to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.

Firefox Won't Open a New Window

I'm setting up my new iMac and installed Firefox as my internet browser. If I close all the browser windows, it won't open another window even by clicking on File>New Window or using keyboard shortcuts. I have to close the program entirely and reopen it to be able to open a window. Any ideas?

Hello and Welcome to Apple Discussions.
Have you trying removing and re-installing Firefox?

BTW this forum is for the much older iMac (Flat Panel) models

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 =)!
Cheers

What does nsAppShell: Event Window mean? Firefox won't open for me at times and I need to restart.

When I return to my computer, Firefox won't open from the "standby" mode. It gives me the message saying "Firefox is already running, but not responding" and I need to log out or restart. Firefox is not running as far as I know. When I restart, a message comes up asking if I want to close "nsAppShell: Event Window". Once I end this process, it restarts my computer and everything is fine. This is very frustrating and happens all the time. What is "nsAppShell: Event Window"?

The OP asked this question 9 months ago and 850 other people have this problem. Why hasn't Firefox Support answered this question or commented?

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.

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.

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
Kris

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!
