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. 
Please attempt to perform a clean reinstall. [https://support.mozilla.org/en-US/kb/forum-response-clean-reinstall (More Details)] 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. 
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.

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.

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.

ITunes 11.1 running in Task Manager but does NOT Open

I have looked areound and no one seems to be having this problem (that I can tell).
My problem started when I upgraded to iTunes 11.1 running Windows 8. When I tried to open iTunes, it never opens but if I open the Task Manager I can see it running (32-bit) with a couple other Apple programs. I have downloaded with both Firefox and Chrome.
I have tried the following things:
Completely uninstalled iTunes following the steps outline by Apple (included checking all folders for files). Same thing happened when I re-installed.
Tried to install as the Administrator.
Tried to run using Windows 7 compatibility
Refreshed my computer (erases and resets everything minus personal files) and installed iTunes 11.1 before anything. Did not work.
Once or twice it would open but as soon as I closed and tried to re-open iTunes, same thing. Never opens but running in Task Manager.
I have no idea what to do next and am running iTunes 11.1 on an OLD desktop that is not sustainable.
Thanks in advance.

Firefox wont start up or launch even right after disabling add ons but lauches once it's in safe mode, already uninstalled and reinstalled and still the same.

i dont know if this matters but here's my computer specs:

please need your help on this.

You can try to disable hardware acceleration in Firefox.

You need to close and restart Firefox after toggling this setting.

New Upgrade has Itunes running in Task Manager but not starting...

I know this is an issue that has been addressed on many other forums as I have been searching for the answer since I downloaded ITunes 8*.
The install seems to work but when I start it up it does nothing. The Task Manager shows it as running in Processes but that is it.
I have already tried the "msconfig" fix. The "corrupt library" fix and I have already confirmed that my firewall isn't stopping it.
Please help it seems that I may be stuck at Version 7.43 for awhile.

odd combination of symptoms you've got there. the "flash" of the license screen usually suggests malware ... but the persistence of itunes.exe in Task Manager suggests dodgy configuration files, or security software interferences.
will go with the latter "persistence" symptom first. if you've got Norton Internet Security 2005 on the PC, first try the Lorraine M technique:
Lorraine M: NIS/itunes problem rectified
... but if NIS 2005 isn't a factor, let's check on this possibility:
iTunes for Windows doesn't open after upgrading
(may not be back to check on this for a while. i've got about a 100-reply-notification backlog, and i'm going to have to get some sleep before attending to that.)

I updated win7 and now I cant see ff. I have reinstalled it 5 times now. It shows it is running in task manager but it is not visible on the desk top.

I installed win7 ultimate and then ff. ff worked fine until I installed win7 service pack 1 and all the other updates it recommended. I click to open ff and nothing happens. I look in task manager and it shows it is running. It is not visible on the screen or in the task bar. I have reinstalled a fresh download of it 5 times. I even tried the beta version but still the same problem. I can use explorer and chrome ok but not ff.

The "System Tray" is located at the very bottom right of your screen and is a list of most/all running applications that will show in this list.
For your SysFader issue, this "may" be the problem:
1 Find the "My Computer" desktop icon and right-click it. A pull-down menu will appear. Select "Properties."
2 Click on the "Advanced" tab. This will load a new page of options.
3 Select the "Visual Effects" tab at the top of the window and deselect "Animate Windows when minimizing and maximizing," "Fade or slide menus into view," "Fade or slide Tool Tips into view" and "Fade out Menu items after checking."
4 Click "OK." This will remove most if not all of the Sysfader effects, at the same time correcting related errors that used to come up during opening a new file or program.

Firefox process starts & is running in Task Manager but browser doesn't load-no errror msg, just nothing?

-Re-installs don't help, either saving profile or complete uninstall (all registry items removed and profile, other directories deleted).
-Sometimes loads browser, once after starting 'plugin-container.exe' process first - but could of been an accident...

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 is running in task manager, but browser does not open.

this happened after most recent update v 27. gateway running win8, worked everyday before this update, does not work now.

Sounds good.
Since you know how to move bookmarks, you probably could move other relevant data if you wish (details on what is in the different file: [[Recovering important data from an old profile]]).
If you discover problems with the new profile after shutting down and restarting Windows, there could be some external process running that is causing this problem (whether injecting an add-on or modifying a file).

My Firefox won't quit and gives a "not responding" message after I use Google Mail. I have tried starting in "safe" mode and the problem still occurs.

I have an issue where Firefox wont' quit and gives a "not responding" message after I have been using Google Mail. It works fine when I am not using that program. I have tried Safe Mode and the problem still happens when I go to Google Mail, so it is not connected with add-ons, extensions, etc.

Firefox won't start, profile manager won't start, but firefox.exe shows in processes list (task manager)

Firefox will not start, even though it is listed in my processes in task manager. Can't get profile manager to start either.
I have tried the following to no avail:
- try to start FF in Safe Mode, doesn't load
- started Windows Vista in Safe Mode, FF still does not load
- turned off Kaspersky AV, FF still does not load
- uninstalled FF, cleaned out user/####/AppData/Mozilla/Firefox folder, as well as ProgramFiles/Mozilla/Firefox folder, and cleaned our Registry manually from all references to Firefox. Downloaded FF 3.6.3, installed. still does not load
- whatever i seem to do, does not fix the problem. When I try to start Firefox, no window appears. I can see the process starting in my task manager. I can "end process" and try to start the program again by double-clicking program icon. Process starts in task manager, but no app window appears.
I am frustrated and have just wasted 2+hours of my night trying to get this to work. Downloaded Google Chrome, unless there is a fix for FF (which I would prefer to use), i will have to switch to Chrome.
I can't pinpoint when this trouble started, but may have been after a recent Windows Update. I already did a System Restore to a restore point about 5 days ago (the oldest one available to me, and I believe that was before the FF trouble started). This has not helped either.
I have run a full virus scan with Kaspersky and a Full scan with Windows Defender. Nothing came up.
Anyone else been able to find a solution to this?

I found a way to make it work somehow but not really fixing the error... one day when I got really pissed off because FF just won't open, I clicked the icon and killed the enter button, then multiple FF windows appeared. I tried to open it with just a single hit of the enter or double clicking but it won't work anymore, but repeatedly clicking the enter button (mine works with just 3 hits, sometimes 6) seem to open it. And until now, I have no technical explanation for this.

Everytime i try to open my Firefox i get a window that pops up asking me which browser i want to use to open it. After choosing Firefox it asks to run a C:/Program Files (x86)/Mozilla Firefox/firefox.exe.

Every time i try to open my Firefox i get a window that pops up asking me which browser i want to use to open it. After choosing Firefox it asks to run a C:/Program Files (x86)/Mozilla Firefox/firefox.exe. But my search bar says file:///C:/Program Files (x86)/Mozilla Firefox/firefox.exe. Never seen anything like this, half tempted to stop using Mozilla for this sole fact. PLEASE someone help me.

Same error message, I disabled tab mix and made sure I only have the newest version of Java, restarted firefox, now it seems to be fine no error yet on Pogo games or pictures upload to ebay which were the biggest problems besides hanging. I had also had disabled AVG secure search yesterday but that did not solve the issue. Now I will try to add back in AVG search...I have very few adds ons, also the note embedded about re- installing a toolbar went away, my old one did not work with FF4, so I installed Yahoo toolbar but the message still did not go away until I applied this fix. Hopes this helps someone..

When I start Firefox, the process starts running but no browser window appears.

Recently, I tried to start up Firefox and no browser appeared. Not sure of what to do, I uninstalled Firefox and installed the latest version. I have still have the same problem. The process appears to be running in the task manager, but no browser window ever comes up. I'm running Windows 7 Ultimate (operating system is up to date minus two security updates). I believe that I installed v9.0.1. Any help would be greatly appreciated.

I have the same problem - every time I close firefox (using either the red x or by selecting file ---> exit) the program appears to close normally, but the firefox.exe *32 process continues to run. If I try to re-open firefox normally I get a message that the program is still running and I need to go into task manager and manually kill the process.
I could also kill the process from the command prompt, but both of those methods are slow and annoying. This issue has only been occurring for the last 24 hours or so; to the best of my knowledge I haven't downloaded any new software or updated any plug-ins that would have caused a switch from firefox's normal awesomeness. Norton doesn't show any new viruses or other nastiness on my computer.
I'm running 64 bit Windows 7 Home Premium edition.

Firefox will not start, will not open in safe mode, and still will not work after clean reinstall, Mac/OSX

One moment I was using Firefox the same as I always have. The only difference was that I changed the preferences to erase history when quitting Firefox. When trying to open the program again, it is immediately unresponsive. I attempted opening it in safe mode and a window will appear but never load, and Firefox remains unresponsive. I could not reset Firefox either. I deleted the application and re-downloaded Firefox, but it changed nothing. I am in OSX 10.7.4. Can anyone help?

Hello chillman4130, try to create a new profile(in case that you profile is corrupted), go (with closed firefox...... it is anyway) to /Applications/Utilities > Open the Terminal application > in the Terminal application, enter the following:
* /Applications/Firefox.app/Contents/MacOS/firefox-bin -p
Press Return
the above opens Profile Manager, if the profile manager open then see : [https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles#w_creating-a-profile Creating a profile]
then see: [https://support.mozilla.org/en-US/kb/Recovering%20important%20data%20from%20an%20old%20profile Recovering important data from an old profile]
