Firefox Application will not start unless in PC Safe Mode

== Issue
==
I have another kind of problem with Firefox
== Description
==
A couple of days ago after seemingly working fine the day before Firefox suddenly decided to stop working. I seem to recall updating both my Adobe Flash and my Java on that day, and I'm also not 100% sure that I didn't change my Overclock settings too (but I think I did that and Firefox was still working)
Basically if I "start" Firefox from any location be it shortcut, direct executable or otherwise the application does not "run" I get the process but that is all. I have tried renaming to various combinations but still nothing appears to have any effect. Using the -profilemanager suffix in my shortcut / startmenu search and creating and using a new Profile has no effect either as does deletion, and Firefox Safe Mode shows the settings window but after choosing to open in safe mode nothing happens and I am left with the Firefox process hanging there doing nothing. I have tried multiple compatibility and administrator run settings but no effect.
I have uninstalled, reinstalled. Done full cleans deleting everything to do with Firefox and its Profiles. Uninstalled Flash and Java, and then Reinstalling FF. I have scoured the registy deleting anything obviously connected to Firefox, Mozilla and even Java to no effect (I have not cleaned out for Flash due to having multiple Adobe apps which I would prefer not to screw up.) I have downgraded from 3.6.3 to 3.6.2 and as far as 3.5.1 and then doing upgrade to the new 3.6.4. All with the help of my CCleaner to tie off any loose ends, but nothing seems to work. Can't restore pc to earlier date as I only remembered about it after I had already made too many changes.
The only time I can manage to run Firefox properly at all is when I am in Windows Safe Mode, I am sick of Google Chrome as it feels really slow and I also dislike Safari, Opera and Internet Explorer. I really do not know what else to do and would really appreciate some help so that I may use the only good browser that I have found again.

Firefox will only open in safe mode and other issues in Firefox 3.6.8
Rig / Set-up:
Win 7 (U.S.) / Ultimate 32bit
• P.O.S. Internet Explorer not installed…
• Firefox Default Browser
This Event:
1. Firefox will immediately close after opening 2 blank (Untitled) tabs and /or 2 (Untitled) windows.
2. Firefox will not open a 2nd time.
3. Firefox will only open in Safe-mode (.exe))
4. Firefox excruciating slow Start-Up
5. Firefox web –surfing unbearably slow
6. Firefox unpleasant web page hanging behavior
7. Firefox awful flash content behavior / Obnoxious Adobe Flash Player has always been and will always be crap.
The Cause:
Session Manager = Corruption …!!!
o This issue was created by faulty and inconsistent and flawed M$ Win 7 legacy software support for Hardware.
 The Keyboard / Hardware would generate a separate session manager event with the action/Web key.
 Firefox and/or TabMixPlus session manger were corrupted in the event process.
The Source:
A: Microsoft Windows 7 Ultimate32-US Version = substandard legacy device handling :
B: Hardware/Keyboard (shortcut) Customization Software Conflicts causing Corruptions of Firefox-Session Manger.
The Fix..!!!
I. Remove from Add and Remove Programs (Win7) Hardware/Keyboard Software “only”. ..Special note: Win 7 Updated- Hardware/Keyboard Device driver does not have to be removed...!!
II. Clean and remove all Instances of Keyboard software.
a. The “Best-est and Safest” Registry Cleaner is jv16 2010 Power Tools.
b. Restart Computer.
III. “If” available install an older version of your “Hardware/keyboard software” compatible with Win 7 that will allow some customization of Hardware/Keyboard-keys.
Confirm fix by:
1. Restart Firefox from Hardware/Keyboard key (shortcut).
2. Clean-up Internet crap and corrupted session managers...
3. Test Launch keyboard shortcut of Firefox.exe [“after” a clean-up of all internet crap]…
4. Test launch keyboard shortcut again / use Firefox extensively or normal use for any recurring bad web behavior.
If Corruption events occur again:
i. Use different and / or Older Keyboard “software” with win 7.
ii. Or you will have to wait for a Win 7 Hardware/Keyboard software update for keyboard installed.
Note:
“Do not use the hardware or keyboard shortcut-key for Web Browsing… Or else: // This Event (See Above): …Will Continue..!!!..”
And it is “not” a Firefox 3.6.8 issue.
So, look elsewhere.
Look @ the main culprits:
a. Substandard legacy device handling: Micro$oft Windows Operating System in combination / with.
b. Customization Software for your keyboard or other hardware that generates web functions and web sessions. / Hardware driver may not be the problem.
Add-on:
Flash Switcher Win / 1.0.2_
DownThemAll! / 1.1.10__
Personal Menu / 4.3.2__
Tab Mix Plus / 0.3.8.4__
Theme Font Size Changer / 0.2_
MR Tech Toolkit / 6.0.4__
Menu Editor / 1.2.6
It is with hope that this solution may help someone.?
Happy Foxing..!!!

My MacBook Core 2 Duo will not boot up. In safe mode I see keychain problems and Mach 1102.

My MacBook Core 2 Duo will not boot up. In safe mode I see keychain problems and Mach 1102 and it keeps circling through the same error. Also the screen is so faint (pressing the F1 and F2 keys don't do anything). I got this from a friend and he didn't have any of the original discs. Any suggestions? From what I've read it's a problem with a recent update. I've never had a Mac so I'm trying to learn and fix it.

I just had an issue like this. I was able to boot up with an external firewire drive, although it was a lot of trouble. I think doing an option boot finally worked; holding down the option key, I eventually got to see the firewire drive was bootable, and booted from it.
I put the thing in verbose boot mode (command - v , I think; but please look it up. I have no Mac books at work to check). In verbose mode, you could see that the hard drive could not mount; the OS tried to do fsck, but it failed around 2/3 of the way, and the CPU was halted.
I was occasionally able to boot normally, but never in safe or single user modes; these do a disk test first, which invariably failed.
I could see from the system and console logs when I managed to get the firewire boot going that there were repeated errors trying to access drive s03, the internal SATA drive. The logs on the SATA drive showed huges numbers of errors. At a wild guess, for some reason a lot of sectors went bad all at once. There had been a some erratic behavior before, but I'd put that down to the single processor G5 problems. (these were non video related, just freezes).
Applecare wanted me to carry the huge thing into the local Apple store, but I persuaded them to just send me a replacment hard drive, which they did. The new one works perfectly.

Firefox 4 will not start after upgrade to OS X 10.6.7 (from 10.6.6)

Was running FF 4.0RC1 successfully on OS X 10.6.6. Upgraded to 10.6.7 and FF would not start; had to force quit. Upgraded to FF 4.0RC2 and then 4.0; same thing is occurring. Reverted to FF 3.6 and it works fine under 10.6.7. Installed full upgrade of 10.6.7 to try to fix this; same problem: 4.0 will not start. Tried trashing Firefox application and restoring anew; same problem.

Since your other Mac running 10.5.8 is not affected, you know that your AirPort router is functioning correctly.
What changed on your Mac? This seems like a post for either the Mac OS X v10.6 Snow Leopard support area, or the support area for your model of Mac.
We normally handle questions about the AirPort Express, AirPort Extreme or Time Capsule in this area, but you can certainly wait to see if you receive a response here.

HP TouchSmart application will not start

We purchased an HP IQ 526 TouchSmart desktop with Windows Vista Home Premium 64-bit machine approximately two months ago. We use Clearwire to connect to the internet. About a month ago the HP TouchSmart applilcation stopped working. It will not start. Every time we try to start it we get the following error message:
HP TouchSmart Calendar has stopped working
A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.
Sometimes it says it's the HP TouchSmart Notes has stopped working or one of the other TouchSmart applications. I went to hp.com and updated all of the software for the TouchSmart application and Windows Vista. And I reguarly use Windows Update to ensure my OS is current with Microsoft security updates. I also updated the firmware. After these actions and rebooting many times the application would still not start. At this point I contacted HP customer support. We uninstalled HP TouchSmart, then reinstalled. This didn't work. I continue to see information events in the Windows Application Log almost every minute regarding HPTouchSmartCalendarNotes. They are typically the following messages over and over:
Reminder clock elapsed event is successfully fired.
CheckReminder() is executed successfully.
ShowReminder() is executed successfully.
After Fetching the XML nodes, checking for each node is done successfully in ShowReminder()
Events in Events.xml Before Showing Reminder<DataRoot></DataRoot>
I still have a case open with HP support and they said uinstalling the OS and reinstalling is likely the next step but I have to believe someone else has run into this issue or HP has a QFE for this issue. I really do not want to uninstall the OS and reinstall it. This has become very frustrating as the HP TouchSmart application is the primary reason we purchased the computer so my wife can manage our photos and music collection via the touch screen.
If anyone has seen this before or has a solution I would love to hear about it. We are considering taking the computer back if we can not resolve this issue.
On a related note and this might be a separate issue I continuously get HPTCS stopped working messages. I've searched the internet for what HPTCS.exe is and what is does but there is little to no information available.
Please let me know or if there is additional information I could provide that would be useful for troubleshooting.
Cheers,
G

Our machine was sent back to HP and they reformatted our hard drive and sent it back. Wow. Fantastic service. NOT!!!! I could have done that. Without debugging their own software to figure out why this was happening they reformatted the hard drive. I can only expect this problem will happen again since there must be a software update, etc... that is causing this behavior. I honestly do not know how to voice my disgust in their customer service. I have been a long time fan of HP and we basically only buy HP at work but this was the poorest display of customer service I have ever encountered. If your TouchSmart application stops working and the TouchSmart software updates do not resolve the problem you might as well pretend like you bought a normal computer without touch capabilities. Like buying an iPhone without it behaving like an iPhone.

In XP Mode on Windows 7, after installing application as like I would normally on an actual XP system, application will not start in windows XP mode itself.

Just did a clean install of windows 7. I then downloaded windows XP mode and Windows Virtual Mode. Everything ran flawlessly and everything is updated. I needed to Install a program called Dentrix 10.5 which can only be installed on Windows
XP for numerous reasons and one including it needing to use Microsoft .NET 1.0. I installed this program on Windows XP Mode as I would as if I were installing it with a computer with windows XP. The Install of the program went fine and completed.
Still being in Windows XP Mode I wanted to see how it would run. I hit Start Menu, All Programs, Startup Programs, and clicked on the Dentrix Application. Once I clicked it the time glass on the mouse was there for a few seconds and
then went away without the application starting up at all. One thing that I'm thinking is why after I clicked Start Menu, All programs, is why was Dentrix not in its own folder and instead in the Startup programs after All programs? Any Ideas how
to get the program to run? Like I said, I am trying to run the program in Windows XP Mode and not Windows 7 as I have found many Q's and A's on only how to do that. Also this is the second application which I downloaded and the first being Microsoft
Security Essentials so I know I don't have some virus from keeping from opening the Dentrix Application. Incase you are wondering the Microsoft Security Essentials opens and runs fine in Windows XP Mode. So Pretty Much My Main question is: Why
my application not starting up in Windows XP Mode? Any help is greatly appreciated!

Once I clicked it the time glass on the mouse was there for a few seconds and then went away without the application starting up at all.
A couple times a week I open Dentrix 11.0 in a virtual machine on Windows 7. I experience the same thing almost every time I open the VM. I must first get Windows to "reconnect" my network for me. Do this by opening Start | My Computer, and
double-click on the mapped network drive leading to the Dentrix data. After I can see the Dentrix data drive, Dentrix will be able to read it too and will open correctly.
In Dentrix, seeing nothing (or briefly seeing a hourglass and then seeing nothing) is a classic sign that either:
- The database files are marked as Read Only
- The program cannot access the data files (probably the folder it is pointed to does not contain any data).
- Or possibly the database path does not point to the right location where the data files are located
Open the folder where you installed the program files of Dentrix (probably c:\program files\dentrix\) and double-click to run EP.EXE. The database path will be revealed. You can "Browse" to the correct location, and "OK" through the dialog to
close them. Then try opening Dentrix again.
Should that not work, open Start | My Computer, and try to open the path (starting with the drive letter, then the folder structure you saw in EP.EXE).
By the way, if your path uses UNC (starting with two back-slashes and then the computer name of the server), you'll need to map a network drive and replace your path with a mapped drive path. (Map a drive in Start | My Computer | Tools | Map Network
Drive). Dentrix really doesn't like UNC paths.
Dentrix 10.5 can only be installed on Windows XP
Microsoft .NET 1.0
Just FYI, Microsoft .Net Framework 1.0 is required only for the "Time Clock" feature of Dentrix. Windows 7 already has .NET Framework features up to version 3.5 built in, and Time Clock (in my experience) works great under Windows 7 without installing
.NET 1.0.
Have you tried installing directly in Windows 7? I have a specific reason why I don't (I have a newer version of Dentrix installed on my Win 7 machine, and use the VM to go back to an older database occasionally - so I can't mix two different program versions
on the same machine). If you were to try installing this program under Windows 7 directly, Dentrix will launch the Microsoft .NET Framework install after the Dentrix install is completed. Just cancel out at that point (Windows will probably give you an "incompatibility"
error message anyway before allowing the install to go through) and I believe you can run it under Windows 7. That might eliminate the networking-through-the-VM issue. So, if you have no other reason not to install Dentrix on your Windows 7 machine directly,
I'd try it. You might be surprised and if it works, you'd save yourself some headache with connecting the to network through the virual machine.
Is why was Dentrix not in its own folder and instead in the Startup programs after All programs?
During the installation, on the Select Program Folder screen, you must have clicked the "Startup" option under Existing Folders. By default, "Dentrix" will be typed into the box at the top. If you simply clicked Next, it would have gone
to the correct location. The screen is a little confusing, because something in the list will be highlighted by default, but what is typed into the box at the top will actually be used.

hello Singyt, the bug report associated to this kind of crash indicates that it might be a malware related issue.
your crash report also shows a file named "urixalog.dll", which doesn't turn up any search hits on google, which is also slightly suspicious. could you search for that file on your pc and upload it to a site like virustotal.com in order to analyze it.
please do a full scan of your system with the security software already in place and/or a different tool like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes].
[[Troubleshoot Firefox issues caused by malware]]
edit: the bug report also suggests that a monitoring program named spector pro/360/... which essentially acts like malware, might cause the issue. in case you have that installed please remove it. otherwise [https://support.mozilla.org/en-US/kb/Firefox%20crashes%20when%20you%20open%20it#w_backdoor-ulrbot-c here] would be a removal guide for urixalog.dll

Firefox will not open even in the safe mode

Started with the addition of beta 4 where gmail would not open and it froze firefox. Added whatever the new addition was yesterday (3/14/11) and then firefox would not even open. Tried safe mode but it still will not open. Error message below

Do a clean (re-)install:
* Download a fresh Firefox copy and save the file to the desktop.
* http://www.mozilla.com/firefox/all-beta.html
* 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.
Create a new profile exclusively for the Firefox 4 version and create a desktop shortcut with -P "profile" appended to the target to launch that profile.

I upgraded to FF 3.6.10 and now FF will not run at all. (Safe Mode will.)

I upgraded to FF 3.6.10. I have tried opening/starting FF from the Start Menu, from the Desktop FF Icon, and from the Program Folders Mozilla folder.
When I try to run FF, it will not start. In the Task Manager, FF shows up in the list of Processes -- for 1 second or less, and then disappears.
FF Safe Mode, however, will run.

If you do not have the original install DVDs, use the Aperture Trial installer instead:
Try if this download link for the trial version still works: if yes, you can unlock it with your serial number:

For about a week now, Firefox will not start unless I re-install it, then it works for about a day and does the same thing. I have gone through all of the fixes

I am on the current Firefox version. I am running Windows 7 Professional with all current updates, and I run McAfee. As stated, I have tried all of the possible fixes your site discusses and have made sure McAfee is setup to allow Firefox full access. I am not sure what to do. Doing a reinstall fixes it for 12 to 24 hours. There is no message, just does not start and there does not seem to be a process running.

Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox and any leftover program files and then reinstall Firefox. Please follow these steps one by one:
#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) and confirm all upcoming messages.
#Now, uninstall Firefox by following the steps mentioned in the [[Uninstall Firefox from your computer#w_uninstall-firefox|Uninstall Firefox]] article.
'''IMPORTANT:''' On Windows, the uninstaller has the option to remove your personal data and settings. Make sure that you do '''not''' check this option; otherwise all of your bookmarks, passwords, extensions, user customizations and other Firefox [[Profiles|user profile data]] will be removed from your computer.
After uninstalling Firefox on Windows, delete the "Mozilla Firefox" program folder, located by default in one of these locations:
* '''(On 32-bit Windows)''' ''C:\Program Files\Mozilla Firefox''
* '''(On 64-bit Windows)''' ''C:\Program Files (x86)\Mozilla Firefox''
#Go to the Windows Start menu and click on "Computer".
#In the Explorer window that opens, double click Local Disk (C:) to open the C:\ drive.
#Find the "Program Files (x86)" folder or "Program Files" folder.
#* On 32-bit Windows, double-click the '''Program Files''' folder to open it.
#* On 64-bit Windows, you will see a "Program Files (x86)" folder AND a "Program Files" folder. Open the '''Program Files (x86)''' folder.
#Look for a '''Mozilla Firefox''' folder. If you find one, right-click it and select ''Delete'' and confirm that you want to move the folder to the Recycle Bin.
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.
Please report back to see if this helped you!

Firefox will not start unless reboot has been done. If start is attempted, Firefox gets hung up, cannot close or log off from Windows.

I can start Firefox when I have just rebooted. If I close Firefox and come back later and try to restart Firefox, it tries to start but never does. A Control/Alt/Delete shows that it is running, but it does not load the screen. I cannot turn Firefox off or log off from Windows.

Firefox crashes - will not start at all

If I try and start Firefox all I get is the Mozilla Crash Reporter, if I try and restart Fireofox from the Crash Reporter screen all I get presented with is the Mozila Crash Reporter again. If I try and submit a crash report the Crash Reporter states "there was a problem submitting your report", hence no crash ID available.
The issue started when I updated my old, maybe version 5, Firefox with version 9, since then I have been unable to start Firefox.
I have tried unistalling Firefox, including deleting personal settings, and restarting the PC in between deleting Firefox and attempting to reinstall it. None of this works. Firefox will also not start in safe mode.
Mozilla Crash Reporter details added to the below Troubleshooting Information info box.

Does Firefox start if you boot Windows in Safe mode (press F8 on the boot window)?

Firefox 4 will not start on Windows 7 64bit

I just upgraded my installation of FF3 to FF4 and the installation seemed to go off without a hitch.
I left the "Launch Firefox now" button ticked and hit finish. Then nothing...
I can see that the process is being started (from Task Manager), but it doesn't do anything. There is no safe mode option available for me to try and restart it, so my only option is to kill it.
I have tried installing normally, advanced, "Run as administror", restaring my PC; none of these worked. Every time the process starts, but nothing happends. Not even a task bar windows comes up.
In the end I had to download (in Internet Explorer, yuk!) an older version of Firefox (3) and reinstall using this. This at least made it work again, but I still can't get FF4 working!
I updated it on my other personal PC and it worked fine (all addons the same, but older hardware).
In case it's relevant, I have heard of some annoyances with hardware acceleration and if I could get to the option to turn it off I would.
My particular hardware is:
Processor: Intel(R) Core(TM) i7 CPU X980 @ 3.33GHz
Memory: 12288MB RAM DDR3-1600MHz
Hard Drive: RevoDrive X2 240GB
Video Card: NVIDIA GeForce GTX 580 SLI
Monitor: LG M237WDP 1920*1080
Sound Card: M237WDP-1 (NVIDIA High Definition Audio)
Operating System: Windows 7 Ultimate 64-bit (6.1, Build 7600) (7600.win7_gdr.101026-1503)
Motherboard: Asus Rampage III Extreme
All drivers are up-to-date, bar my OS which is fully up-to-date bar having SP1 installed. No other application are having problems.
Any help would be greatly appreciated.
Thanks.

Solved it!
It was a dodgy version of Firebug (1.6.2) running, which would kill the disable/update process. It was killing something on the first run that would corrupt my Firefox.
How I fixed it:
* Download the latest Firefox
* Install Firefox 4 (as Standard) in-place upgrade
* Before finishing, un-tick the "Run Firefox Now" button
* Hit Finish
* Find Firefox in the Start Menu and hold Shift and click the executable (safe mode)
* Leave everything disabled
* You should now have a working Firefox!
Remove/update your add-ons as needed. I only had to upgrade Firebug in safe mode to get it working.
Odd how the check for updates completely broke this Firefox, wonder what was so bad about Firebug.
Hope this helps at least one other person! The "Run in Safe Mode" option is so hard to discover now when your browser is broken!

Firefox 5 will not start with Zone Alarm Ver 10.0.240.000

Firefox updated yesterday and now it will no longer start, it looks like the probem may be with Zone Alarm Forcefield. Does anyone have any ideas how to get Firefox 5 to tun under Zone Alarm Extreme Security? Thanks

Hi,
I'm running Win7 x64 with ZoneAlarm Extreme Security 10.0.241.000
I had the same problem with Firefox 4. After turning off ForceField Toolbar, it started working fine.
Then I updated to Firefox 5 and it wouldn't start, instead it was showing an error message from ZA...
I searched mozilla support and followed the instructions here: http://kb.mozillazine.org/Browser_will_not_start_up
on the topic"Firefox does not start after updating with ZoneAlarm ForceField enabled".
The correct instructions for this ZA version should be: "'''Internet '''-> '''Web Security '''-> '''Settings''', and click '''Clear Virtual Data'''"
After that I could open Firefox again! Then I realized it was still version 4...
I installed the update, and everything went smooth. Checked again if Forcefield toolbar was inactive (it was) and opened a few pages, closed Firefox and opened again. After a while it wouldn't open...
AGAIN the "Clear Virtual Data" did the trick...
This time I clicked on '''Settings '''(next to "Clear Virtual Data") -> '''Advanced Settings''', and turned off "'''Enable Virtualization'''".
Until ZA get a fix for this, either we turn it off or clear virtual data every few moves...
Working fine.
Best regards

Firefox 32 will not start after a download.

If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.
*Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
