Firefox keeps switching into Safe Mode, necessitating restart

Firefox keeps switching into Safe Mode, necessitating Mac restart to get my extensions back. I'm fed up! -- I keep having to shut down umpteen apps to restart.
Thanks for any insight,

Can you give a description of what you call "Safe Mode" From my reading, the "Safe Mode" is something added on by a specific tool used to Jailbreak an iPhone. Unless you are talking about something different.

Firefox abruptly switched into safe mode. How do it return it to normal mode?

I use Firefox with Google Search as my home page. Today (12/3/10) I closed the page and was informed that Firefox was not running in safe mode and all my preferences--bookmarks etc.--were not available. I managed to restore bookmarks and other features by following directions on a screen that gave me those choices. However the Firefox
icon has disappeared from my opening screen and I cannot figure out how to restore it. Firefox is still listed on my menu as in safe mode. If I bring up the home page and try to right click to create a new icon, I get a screen that tells me how to restore (or delete) those preferences I have already restored.

Thanks for the suggestions, but I could not make them work. The easiest route for me turned out to be uninstalling the program, keeping my preferences intact and reinstalling the browser. Seems to work fine now. Icon was restored and when I deleted the "Firefox (safe mode)" from the menu, it was instantly replaced by the name of the browser in normal mode.
I still don't know why or how this happened, but the solution above seems to be satisfactory and it didn't take too long.

Firefox has gone into safe mode. what happened and how do i fix it?

when i loaded firefox it went into safe mode and now firefox is useless

How do you know it is in Safe Mode?
Normally closing Firefox - Firefox button>Exit or File>Exit - and waiting a few seconds before re-opening should put you back into Normal Mode.
If not, check with Task Manager and close Firefox if it is still running.
Please sign in when you report back on progress. You may need to do some troubleshooting. Full system details would help.

Mountain Lion (upgrade from Snow leopard) Have to go into safe mode then restart in order to get to login screen.

I have reciently upgraded to ML from SL and I have to boot into safe mode then restart in order to login to the syatem I have inplugged all peripherials, removed all startup programs and uninstalled or disabled any software that was not important.
Any help would be appreciated thanks in advance.

What happens if you don't boot in safe mode first?

Keeps booting into safe mode ..

I just tried to install the newest version of Lion and it didnt install successfully and now it boots up in safe mode every time. Please help I'm a new mac user and this is not a good first experience for me..
Oh and when I actually boot it into safe mode myself, it says no hardware installled on the wifi.

What happens if you boot up holding command-r keys into your Recovery Volume.
The screen should give you these choices...
Restore from TM backup
Reinstall Mac OS X
Get help online
Disk Utility
First run Disk Utility Repair Disk, if you get errors run until no errors reported or reports "the disk cannot be fixed". Then, choose Reinstall OS X. This will be an install "in place" and shouldn't effect any of your own data or settings.

Firefox keeps crashing outside safe mode (resetting, uninstalling-reinstalling, & disabling all add-ons do not help)

I have actually been having this issue for over a year now with the previous versions. The browser always crashes right after I start it, but it seems work well in safety mode. I have tried resetting the Firefox, disabling all the add-ons in safety mode, and reinstalling the application, but none of these methods seem to work. Here are the crash reports I have after I installed the newest version tonight:

Seems the crash reason is "EXCEPTION_ACCESS_VIOLATION_READ," whatever it means...

I can't lock Firefox into safe mode on You Tube.

I use Firefox 24 and have followed all the directions given to me by You Tube in order to lock the website into safe mode on the firefox browser. It works until I close firefox. Once I open it again it doesn't remember the setting and goes back to normal mode. It is supposed to be locked in for that browser until someone logs in under my google account and changes it back. I can lock it in Chrome and IE with no problems. I am about uninstall FIrefox...please help!

Hello Ammonthomas, if you started Firefox in Safe Mode, it will remain in Safe Mode until Firefox is completely closed.
i think an option is to make the site you want (You Tube) one (or the only) homepage and set firefox shortcut to open in safe mode : right-click the firefox shortcut > properties > target > change the target to : "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode
'''BUT''' firefox with that, always start in safe mode (you lose the normal mode) !!!!
why do you want to run You Tube in safe mode ?
where is the you tube video to lock the site in safe mode ?
thank you

Cannot log on to firefox home and can't get into safe mode

Thanks for the effort but it doesn't help me.
I have the same problem that the progress bar stops at 1/4 the it reboots in the normal way..but the big difference between me and the other user is that i am stucked at the apple boot logo and i can't access to my computer and right now i really need it.

I don't really know how to do and it seems that this problem haven't been solved yet by other people.
This remembers me windows world.
Miss steve J.
Anyway, if anyone has some ideas please tell me.

When I open Firefox, my computer goes into safe mode. How do I fix this problem?

When I open Firefox to do some browsing, my computer goes into safe mode. When I close Firefox browser, then it goes back to normal. I know there has to be a simple fix, but I have not found it.

Check that you do not run Firefox in compatibility mode or with a reduced screen resolution.
You can check that in the "Compatibility" tab in the Properties via the right-click context menu of the Firefox desktop shortcut.<br />
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.

How to boot T42 into safe mode

Hi all, first post.
I have a T42 with Firefox 4 installed that is giving me trouble. I want to be able to boot into safe mode to help troubleshoot the problem.
I have tried to rebbot and use the F8 key but it does not work. I have tried the F11 key and the Access IBM button and both bring me to the Rescue and Recovery login which asks for a password. I don't have the password as I did not set it up. I read on the forums that I could delete and reinstall R&R and that would reset the password.
I uninstalled R&R with rapid restore from the add/rmove programs panel (sorry, I don't remember which version). I have not tried to reinstall anything yet. When I reboot I still get the R&R ogin asking for a password. This leaves me with several questions.
How do I get around R&R, do I need to uninstall something else?
Is there a simpler way to just reset the password?
How do I find out what version of R&R with RR I had and what should I replace it with. Apparently 4.23 may not be my best option. I assume the original Windows backup partition will still be there. I din not have any backups of my own.
Finally, I just need to get into safe mode. Is there an easier way.
Many thanks for any help!

Try using the msconfig utility's boot tab to turn on the Safe boot checkbox, then restart.
On Windows 7, I can just tap Windows+R, then type msconfig and press Enter. I think in XP, you might see a Run option somewhere on the start menu. Or if you can get into the Task Manager (press Ctrl+Shift+Esc ?), select File > New Task (Run) ... Or even just browse for msconfig in C:\Windows\System32
It sounds like maybe someone has set up a BIOS password -- this may be irrelevant to getting into safe mode.Or if there is a separate R&R password I never noticed, that should be irrelevant to Windows, too.

CFP-2110 will only boot into safe mode + communication error?

Hello all,
I have a new cFP-2110 and I'm trying to configure it. I'm using Realtime 8.0, Fieldpoint drivers 5.1.2 on WIndows XP. My host computer versions match the FP controller software version and the safe-mode dip switch is in the 'off' position.
I even re-formatted the controller memory (like someone suggested in a different thread) but I keep getting the same thing: Connected - Safe Mode (Improper Installation)
Attached is a screen shot of the error I get when I try to 'find devices.' I have a good ethernet connection (although I have a yellow blinking LED on the RJ45 of the controller but not the green). I know this because I can reboot the controller from the host - It just always reboots into safe-mode. Does anybody have any suggestions for me?
Thanks - Paul

cFP-2110 error.JPG ‏365 KB

I finally found the problem and thought I'd share in case anyone else has similar issues:
In troubleshooting I wanted to eliminate network communication errors so I decided to connect directly to my host PC. I got a crossover ethernet cable and connected straight to my host PC's ethernet card. I had to log in as administrator on the host in order to change it's IP address to a static address. Then I re-formatted the FP controller, re-assigned it's IP and finally re-installed the RT and FP drivers. Finally - I had a normal connection!
This made me wonder if it was being directly connected to the host or being logged in as an administrator that was the fix. So I went to a second host PC, logged in as administrator (leaving it as a normal network connection), reformatted my second controller and re-installed the software - and hot damn - it worked!
Moral of this story is - be logged in as admin. before attempting to install any software...

Windows 7 fails to go into safe mode. Stuck at classpnp.sys

Hi, I wanted to go into safe mode on windows 7 but it kept stopping at classpnp.sys . After reading a few threads I read about using Msconfig and checking the safe mode option under "Boot". It still keeps staying at classpnp.sys and when I hit F8 and hit "Last Known Good Configuration (advanced)" it seems to be able to get trough and it says it's actually loading up safe mode but then it changes to a black screen and does not change from that screen. I would appreciate and information you guys have that could solve this problem. If any of you know a command I could type in cmd to bring up the msconfig while in repair mode I could fix it because all I need to do is untick "Safe mode on startup"

This happened to me because I tried to install Fallout 3 too. I tried doing the c:\windows\system32\drivers\classpnp.sys to classpnp.old but then it just stops at the one before and goes on to say windows is starting in safe mode but then it shuts off and restarts.
Glad to hear tat Fallout 3 is still being played.
Firstly there are a few things that I have discovered. Classpnp.sys causes a few problems with the system. As I don't know what your system or brand of computer you are using, I'm not sure exactly what advice to give. However it should work a little something like this. When you start your computer you will see the brand name of the company who built the system (ie. Acer, HP, Compaq etc) Press either alt + F10 or alt + F11.
This will bring you to a recovery type menu. From here you can do a system restore you will loose any un-backed up data. This trick will restore your systems factory defaults systems. I have not been able to try this myself yet.
Also depending on your what OS you are using you could try and and get a hold of either the Vista or Windows 7 recovery disks.
You can download them from here:
http://neosmart.net/blog/2008/windows-vista-recovery-disc-download/
You will need a burning software as recovery disks need to be on disk so you can boot it up during windows start up.
Use this software: ImgBurn
http://www.imgburn.com/
Its free and is very effective (I can see this having more use with other iso files of mine)
Again I have been unable to try this myself.
And the last option short of formatting the drive is to use another piece of software called Ubuntu 9.10 Desktop.
This is freeware that needs to be downloaded (http://www.ubuntu.com/) and then burnt on to a disk using the ImgBurn mentioned above.
Put the disk into the drive and but it up during windows start up.
You also need to download a replacement classpnp.sys file. You get this from http://www.hotfile123.com/index.php?q=classpnp+sys
(I also haven't tested this file yet but there other options on the site)
While using Ubuntu find the classpnp.sys (C:\windows\system32\drivers\classpnp.sys) rename this to classpnp.bak
Copy the recently downloaded version of the classpnp.sys to replace the old one.
Exit and restart. The computer may lag a bit but should eventually boot into safe mode.
Sadly I haven't been able to try this yet either.
Although none of this helps with getting fallout 3 to install any easier.
I will post with my progress and with what works in the near future. Hope any else can do the same.
Good luck.

Why is firefox 13.1 in safe-mode slow running on windows 2008 R2?

Issue I connect to a large company support site and it takes forever to down load the site information.
I do not have this problem with IE.

The problem exists in normal and safe mode. I switched to safe-mode after reading an issue about firefox being slow when to much memory was grabbed by add-ons. So I have the problem in normal and safe-mode. Changing the proxy setting did not help. Thank you to all for the suggestions. Note my windows 2008 R2 is a 64 bit platform.

Will not boot normally, but will boot into Safe Mode... what now?

Hey y'all, I've got an iBook G4—purchased in 2003—that's had its hard drive replaced (due to the OE one failing) and that's on its second battery (which will need replacing soon unless I can't get this resolved, then it's new computer time... ugh).
Last night I left it open and on and probably had a couple of sites open in tabs in Safari, as well as Mail and iChat open (Preview might've been open, too).
When I went back to it this morning it wouldn't come off the black screen (I don't have it set to sleep), and I thought it was because it's dry here and I must've discharged into it through the trackpad (though I've always felt it before), which freezes it, a problem that's happened before and that's normally resolved with a restart. Confirmed it was, indeed, frozen by turning the number lock on and off (which turns the light for it at the top of the keyboard on and off).
Powered it down by holding the power button. On restart it wouldn't go beyond the black screen. Tried it a couple of times, same problem. Things were pretty warm, so I let it sit for a while. Went back to it and it would freeze on the gray apple screen with the progress "gear" freezing after a few seconds of whirling about. Managed to get to the UN/PW screen once, but it froze after entering my UN and PW. Now it freezes on the apple/gear screen every time.
I used the Hardware Test CD to check things and all the hardware tests showed up fine. Booted it into Safe Mode and ran Cocktail. Rebooted, no joy.
Booted again into Safe Mode and backed it up onto an external HDD using CCC. I had done a clone a few weeks ago, but I wanted my most recent emails, etc.
Used Disk Utility to repair permissions. No change. Attempted to boot from my cloned disk image. No go. Repaired some permissions on that drive and tried again. No joy.
The thing "works" in Safe Mode, but I cannot get it to boot into things normally.
Seeing as it was online, is it possible that I picked up some corrupted font that's causing these problems? Got that idea from other stuff I've read online regarding iBook G4 start-up issues and this: http://support.apple.com/kb/HT1564?viewlocale=en_US
Any other ideas?

Gents, truly, thank you.
In safe mode I couldn't disable the Airport card as it was already off and the hardware was "not found". No biggy. I simply pulled it. Booted up normally without a problem several times.
I swapped in a known-good Airport card from another iBook G4 and put this one's in that iBook. That computer wouldn't start and this one started up no problem (and I'm posting from it).
Weird that it would go bad like that, but it did. It's nice to know what the problem is and that the fix is easy. I'm glad I didn't go through any restore or wipe and install procedures.
So, again... THANK YOU!

ITunes causes VAIO laptops to go into Safe mode

Hi, when I open iTunes on my Sony Vaio laptop (Windows 7) everything on the screen changes appears to be in Safe mode. Then it acts like its syncing with my iPod Touch but nothing gets downloaded - some music got removed from my Touch.
Any help would be appreciated.
Thank you,

I have no problems, thankfully. I have Firefox on another computer and somehow FF went into "safe mode." I noticed that it ran faster, with no affect on what I do with the browser, which is nothing fancy. Therefore, I decided to put FF on this computer into "safe mode," too.
I had to ask how to do it because the instructions are not evident where mention of using it to fix problems occurs under 'help.' Why talk about using something without telling how to get to it. Very frustrating! Had it been done, I would not have had to bother folks here. Perhaps bring this omission to the attention of the "powers that be."
