Firefox 12 crashes my OSX 10.7.4 system, even when Firefox is running in Safe Mode

Firefox 12 crashes unexpectedly. The whole OSX system hangs for unknown behaviors, i.e. opening new tab, selecting link, refreshing page, changing tab. It is non-specific or non-apparent. I also have frequent spinning color disks...sometimes they don't go away and the next mouse click hangs the system necessitating a hard reset.
My configuration:
Macbook Air, OSX 10.7.4, Firefox 12
I have one add-in: One Password 3.8.19. I have disabled this by running Firefox in safe mode but this has not helped.
My typical open application set is: Outlook 2011, Mail and Firefox (with multiple pinned app tabs). Sometimes I have VMWare Fusion 4.1.2 open running a Windows 7 VM but this is not correlated to the crashes.
I was using Trend Micro Smart Surfing for Mac and thought this might be the cause so I stopped running it. This had no positive impact so I conclude that it was not part of the problem.
My system knows it has crashed since following a hard reset, it reopens my previously open windows but no crash report is created or offered.
Safari does not crash the system.

I originally posted that, if you are able to run in Firefox [[Safe Mode]] but disabling your single Firefox extension doesn't help, the problem could be hardware acceleration, which you can turn off in your Firefox [[Options window - Advanced panel|Advanced preferences]], General tab. Ref: [[Troubleshooting extensions and themes]]
However, after re-reading your post, you said that the problem still occurs in Firefox Safe Mode. If Firefox is crashing or closing unexpectedly, there are some possible solutions here:

The only other suggestion would be to go through the [[Basic Troubleshooting]] steps.

I have windows 7 operating system - I just downloaded firefox but it is running in "safe mode" rather than normal mode can you teach me how to fix this please?
== This happened ==
Every time Firefox opened
== I downloaded it and first used it

Do you get the [[Safe mode]] start window?

Firefox keeps crashing. Even when i start it in safe mode

I have a Windows 7 64bit computer working with firefox for a long time. Yesterday they think they opened some SPAM message, firefox crashed and isn't working any more. I have performed all actions mentioned below without any succes:
- Firefox does the same starting in safe mode. Removed the profiles and created a new one without importing any settings. same problem
- Removed Firefox, removed all folders, removed all Firefox links in registry. Reinstalled firefox, same problem
- Removed java and flash, firefox still crashes
- created a new user account in Windows, logged on, still the same problem.
- Scanned the computer with Norman Security Suite, McAffee Stinger, Malwarebytes, Superantispyware, TrendMicro Housecall. Except for cookies, nothing was found.
- Windows System restore wasn't configured so unfortunately no restore points available.
User was really happy with Firefox and really doesn't want to use another browser, but now she has to.
Reinstalling the OS isn't really an option, to much settings, software and connections to other devices in the network.
Can Anyone please help????

We're sorry to hear that Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.
#Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
#In that text field, enter %APPDATA% and press Enter. An explorer window should open.
#From that explorer window, double-click on the ''Mozilla'' folder, then double-click on ''Firefox'' and then on ''Crash reports''. Double-click on ''submitted''.
#Now, you should see a list of files that contain reports. Go to ''View'' > ''Arrange Icons by'' > ''Modified'' to get the most recent files at the top of the window.
#Open the most recent 5 files with a text editor and copy the IDs.
#Paste each ID into the reply window on the forums.
Thanks in advance!

Had to start Firefox in safe mode cause it kept crashing after i deleted the file. Now Fire fox Crashes every time I open it and I have to put it in safe mode just to use it, also it's not syncing with my iPad.

If you use Norton software, try disabling your Norton extensions. As of last week, there were severe compatibility issues with Firefox 24.

Firefox only runs in compatibility mode

I have Windows 7 Home Premium 64bit,
I have been running Firefox without any problems, however, today when using it it suddenly crashed and I was unable to start again.
It would display a menu with choices whether to run in safe-mode and some other options, but I would not be able to start in safe mode, because, while displaying the options, "windows is trying to solve the problem" message appears freezing firefox and the only way out is to end the program.
However, If I choose to launch firefox in compatibility mode with XP sp3, I can use it without any visible problems.
The only changes I've done is updating Java yesterday, but there weren't any issues right after the update.
How could I fix this?
/I need the latest Java to run some applications (chess in particular) that requires the latest version/
I don't have anything in the crash log from today

There's nothing from the past week in the crash logs.
However, the problem is now solved.
I disabled Java updater process and removed it from startup. Soon after I was offered to install Firefox version 15. Then I tried to install it, but got a message that it is impossible to do because Firefox is still running and must be closed, that happened several times despite killing the process in task manager.
However in some time the installation managed to start and succeed. Afterwards I didn't have any issues running Firefox in normal mode.
I am unsure whether it was disabling Java updater or upgrading Firefox that solved the problem, but either way it's fixed and good.
Thank you guys for replying though.

I just installed Firefox on a new HP 600-1120 with Windows 7 and it is only running in "safe" mode. Why? How do I get it to run in "regular" mode? How does "safe" mode differ?

Use the Toshiba recovery disk or the Toshiba HDD recovery option.
If you dont have the Toshiba Recovery disk try the HDD recovery:
http://aps2.toshiba-tro.de/kb0/HTD1303440001R01.htm
This works only if the recovery image files from Toshiba are still on the HDD:
If you installed the system using another disk as Toshiba recovery disk, this recovery option will not work.

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 slow wireless but fast wired. No issues running IE wireless. Tried system restore, fact. reset, turned off accl, disabled addons, run in safe mode.....

So i have an HP e118dx running on windows 8.1 with very little software on it. Currently running FF 37.0.1 and in wireless mode it always hangs up, runs slow, or times out. When plugged in it runs just fine. Can get on net using IE via wireless and no issues. So it seems to be something specific to FF on the wireless side. Thought it might have been my wireless card but running IE just fine seems to rule that out.
Have already tried system restore a few times, factory reset, turn off hardware accel., run in safe mode(FF), disabled add ons and nothing seems to help. If i have tabs open while wired, then go wireless and refresh the pages or browse on the already open pages i tend to get a couple minutes of trouble free experience before it slows to a halt again.
To recap....FF on wireless=slow and wired=fast. No difference when using IE wireless---always fast.

Not sure what you mean by # of connections being made. Not sure if that means tabs open, or folks using the actual wireless network. A while back when i was going through this with the isp i got a crash coarse on how to go into the modem and check a bunch of different stuff, as well as reset things. When looking in there only 1 or 2 computers showed on the network. The network is password protected......i guess protected only to the extent that a pswrd can. Not certain if someone nefariously connected somehow.....didn't show up when looking for users on the network though.
The first bullet point......Not sure how to do any of that so i'd say no.
Second bullet point......Yes, did lots of clearing temp files, caches, history, etc. along with systems restores and factory resets. although not exactly sure what you mean by dns cache. Might have done this but don't recall specifically seeing that.
Third bullet point.....It doesn't make any difference on this end whether its on no proxy, auto proxy, manual proxy. While i have no idea what all this stuff does/affects performance i played with it on all different settings and nothing changed here. Put it back to no proxy.
The thing is even when my wireless FF is acting up other devices in the home can be on the wireless with no issues. Think the other devices are using Chrome and some phone wifi hookup. Keep in mind if i switch to IE on the same device with FF windows open the IE will run just fine. At any given time there should only be 1-4 devices on the network so i'm guessing that shouldn't overload anything. Besides none of the other devices ever seem to come into this issue.
There always seems to be some issue that pops up after updates. Can't ever just leave working things alone.

After upgrading to v4 Firefox always start in Safe Mode. How to avoid this?

When I start Firefox, this Safe Mode windows always shows:
[http://imageshack.us/m/593/9760/firefoxsavemode.jpg http://imageshack.us/m/593/9760/firefoxsavemode.jpg]
There is no option for Normal mode and I can't use Firefox 4 normally.
Any ideas?

See [[Firefox is stuck in Safe Mode]]

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.

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.

When I open Firefox outside of the safe mode I get a continous sound of a the "Pac Man" game over my speakers

Firefox 3.6 is running in safe mode . How do i change this.

I want to delete Firefox 3.6 and try Firefox 4 beta. Firefox 3.6 is running in safe mode and i am unable to delete i. I do not want to have both Firefox 3.6 and Firefox 4 beta on my computer at the same time.

So irritating when the window is mis-positioned. Two suggestions:
'''-- New window method --'''
(1) With the Firefox icon active, press Alt+Spacebar and then the letter x to maximize. The Firefox window should appear full screen.
(2) Copy the following line of script code to the clipboard:
<br>newwin=window.open(window.location.href);newwin.moveTo(0,0);
(3) Press Ctrl+Shift+k to open the web console.
(4) Press Ctrl+v to paste the line of code then press Enter to run it. A new copy of the same page should open in a window positioned at the top left of the screen.
(5) Switch back to the maximized window and close it. Firefox should remember the new window's position.
'''-- Rename file method --'''
Note: this will reset all your toolbars to their default settings as well as clearing the last window position.
(1) With the Firefox icon active, press Alt+Spacebar and then the letter x to maximize. The Firefox window should appear full screen.
(2) Open your personal settings (AKA Firefox profile) folder
Help > Troubleshooting Information > "Show Folder" button
(3) Switch back to Firefox and exit the program (e.g., Firefox > Exit or File > Exit)
(4) Wait a few moments for Firefox to finish updating files in your settings folder, then rename '''localstore.rdf''' to something else, like localstore-bad.rdf or localstore.old.
(5) You're done here. You can close this window and restart Firefox.
