Firefox freezes upon startup, cannot change any settings

Since yesterday my Firefox will not open anymore.
It started with a problem concerning all my browsers; I could open them, click inside them, but whenever I'd start typing anything, they would freeze. I'd get a 'Not Responding' message and I'd have to close the programmes. However, a restart fixed this for Chrome and IE. Firefox got worse after that; whenever I open it now it won't even load, I immediately get a 'Not Responding' message and I'm forced to close the programme. I've tried uninstalling and reinstalling.
All support articles here suggest clearing cache and all that, but I can't do anything because it just immediately freezes.

There are two things you can try. But first, holding down the shift key
starts Firefox in Safe Mode. This disables all your add-ons and some
settings. If the browser works find in safe mode, then the problem could
be an add-on. But first do this. Go to '''''[https://www.mozilla.org Mozilla.org]'''''
to download the latest version of Firefox. DO NOT UPDATE. Get the full
installer. After you download the installer, remove Firefox using the
windows uninstaller. Then run the FF installer you just got. You will
not lose much of anything. Now try FF normally. If you still have problems,
then you will need to reset the browser. This will remove ALL ADD-ONS,
and reset ALL SETTINGS to their default settings. If the problem is
gone, then it was one of the add-ons. Re-install your add-ons only a
few at a time. Close FF, and restart after each group. Good Luck.
===================================
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. <br>
'''Note''': ''This will cause you to lose any Extensions and some Preferences.''
*Open websites will not be saved in Firefox versions lower than 25.
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.

Firefox freezes upon startup; forced reset everytime.

Hello, all,
I'm currently running Firefox 25.0.1 on Windows 7 Home Premium SP1 on a Dell XPS 8300, 64 bit OS. Recently, everytime I start up Firefox, it freezes automatically without my clicking anything. I'm then forced to hold down the shift key, while clicking the Firefox icon, in order to reset the browser. I've uninstalled/reinstalled it a few times, but the problem persists. I believe it might be a script issue, but can't be certain. This scenario plays out everytime I start my computer, which really puzzles me that I need to fix it everytime. Any ideas?
Thanks,
Lefky

Just downloaded Firefox 6.0 and have restarted 4 plus times, but it continues to hang while launching. I cannot open new windows, change any settings, or do anything but Force Quit. I'm on Mac OSX 10.5.8. How do I get past this hang?

Long story short: Simply get CC for teams. At 500 bucks a year it's a steal and those 5 licenses in the base package (or was it 10 even?) cover all your computers, at least the 3 ones you mentioned. For system requirements refer to the individual product pages.

You can find the connection settings in Tools > Options > Advanced : Network : Connection<br />
If you do not need to use a proxy to connect to internet then select "No Proxy"
See "Firefox connection settings":

My iPhone safair says it cannot open because it is not connected to the internet. What do I do? I do not believe I changed any settings. I have turned the phone off but this did not work.

Safari cannot open because the iPhone is not connected to internet. I do not believe I have changed any settings. I have turned off the phone and then on, but this did not work. Help?

For Safari to work, you need either Wi-Fi or cellular data.
Are you connected to a Wi-Fi hotspot?
If not is Settings > Mobile/Cellular > Mobile/Cellular Data: ON

I am in Singapore and have a Starhub prepaid SIM card. I cannot access wifi although it is visible on my network list. Do you now if I have to change any settings?

Hi, I am in Singapore and have a Starhub prepaid SIM card. I am a Verizon (US) customer but want to access WiFi. My device shows being connected but I cannot access wifi. Do you know if I have to change any settings to access wifi on a SIM card?

hi, this thread already deals with the issue:
How can I prevent getting calls from number that are not in my address book?

TS3276 I suddenly cannot send e-mail messages. It takes hours to send. I haven't changed any settings.

My mail does not let me send messages. It can take hours for it to be sent. I have not changed any settings, it just suddenly started yesterday.

Hi there Bahtat67,
If I understand correctly you can send mail without issue, but you cannot receive new email. I would recommend you use these steps specifically from the following article, named:
Get help with Mail on iPhone, iPad, and iPod touch
Restart your iOS device.
Delete the affected email account from your device.
Tap Settings > Mail, Contacts, Calendars.
Tap the affected email account.
Tap Delete Account.
Add your account again.
Thank you for using Apple Support Communities.
Take care,
Sterling

I have a MacBook Pro, it recently started freezing upon startup. It would get to a blue screen and just sit there. I've tried booting in safemode to run disk repair and still doesnt help. If I do manage to get past the blue screen, it still freezes

My mac keeps freezing upon startup. It will get to the blue screen and promptly freeze. If I manage to get past the blue screen, and open up youtube on google chrome, it will freeze before it loads youtube. I've tried safeboot and disk repair, nothing seems to work. I even tried to factory reset it but it wont connect to my internet when I reboot with power + option.. any ideas?

This can be used to boot the machine and delelte enough files to get it to boot normally.
.Create a data recovery/undelete external boot drive
Read about storage drive so you can store your extra stuff.
Most commonly used backup methods
Also here to see how a full boot drive slows the machine down
Why is my computer slow?

I just updated to 5.7 and the exported files are blurry. I compared the ones I exported before the change and they are fine. I have not change any settings.

I don't understand your last paragraph.
"The home page also has a full bar ..." What does "full bar" mean? " ... instead of the tray it had before." What does "tray" mean?
Anyway, you might try Settings > General > Reset > Reset Home Screen Layout
I guess that cannot make things any worse.

I cannot change any user account icons

I cannot change any user account icons. Under the Default icons it says "No Items". Any new users are set up with a tennis ball with no other options. In the initial set up, there were a lot of choices. Now they're gone. It there a missing file?

Yes the missing user icons is unexplained and nothing I've tried has resolved it.
It seems to have occurred as part of the 10.8.2 update for me.
No user shows any of the default or custom user icons available in the users system preference. All the Apple icons are present in the /Library/User Icons folder as well as custom icons but they do not appear within the system's panel period. No icons appear there. You are able to add icons to it -per user. Any done in this manner are saved in that user's preferences so this does not affect the system level. I have tried removing preferences. I have tried removing the icons and adding them back including as root but all changes are applied to the user only. I have run Diskwarrior, repaired permissions, etc. And nothing changes this.
I cloned the image to another laptop, deleted all preferences from main library, restarted, logged in expecting it to be a preference issue. Still no user pictures shown for default user. In case the original users were corrupt, I created a new user and logged in with it. It was given one of the OSX pictures randomly chosen by the system. I logged in as user and still no pictures are shown. Tried to do a reinstall of 10.8.2 combo update and system refuses saying I cannot be done. Booted from recovery partition and it allowed an internet recovery.
No change. Took a brand new laptop and used user migration to copy the users over to it with all settings. Broke that system as well. Repeated creating new users, etc and no change. This is really annoying. I can repeat migrating users only and then partial settings to try to narrow it down but its time consuming.

'System Preferences' gets hanged. Not able to change any settings.

I'm not able to change my wallpaper. Main issue is as soon as I open 'System Preferences', the window opens but I'm not able to click on anything. Not able to change any settings. Tried restarting but no help.
Please help.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Boot in safe mode and log in to the account with the problem. First, disconnect all wired peripherals except keyboard, mouse, and monitor, if applicable, and remove all aftermarket expansion cards. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including your login items.
Launch the application(s) and test. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode.)

Calendar last emailed reminders 12th June - suddenly stopped doing that, but I haven't changed any settings.

Windows Vista Home basic - Firefox 4.01. I use Calendar to remind me of my work schedule by email. Suddenly stopped notifications after 12/6/11. As far as I can see I have not downloaded any updates, nor changed any settings/preferences either in Windows or Firefox. Help please. Thanks in advance.

I have the same issue. It began with my 3GS some time around september-october I believe. I purchased an iPhone 4 in November and it does the exact same thing. I did restore my iPhone 4 to a backup from my 3GS when I got it. I have the latest versions of iTunes/iOS. Ok now my iTunes library is on my laptop with 32-bit Windows 7 Pro. I have moved my library from a machine running 32-bit windows xp pro to the laptop running 32-bit windows 7 pro. So I'm wondering if possibly either restoring from a backup, or moving my library has had anything to do with it. Just trying to figure this out...
Apple. ***!?!? Get on this. I am an avid podcast listener and I sync daily to keep my podcasts fresh. I already have to physically connect my iPhone to the computer because iOS doesn't support wireless syncing. But now on top of that I have to hit cancel or apply after EVERY TIME I sync my iPhone. Not the biggest deal in the world. But a huge inconvenience and annoyance. Apple usually prides themselves on the fact that their products "just work". Well Apple, my iPhone 4 DOES NOT "just work".

Workgroup Manager cannot edit any settings

Authenticating correctly even local but in Workgroup Manager I cannot edit any settings, has anyone ran into this I can't find any help for this issue.

We have this problem often.
It happens when we either change an IP address on a NIC, or when we unplug a network cable etc.
I'm not sure what the proper way to resolve the issue is, but this is what we do.
1. Log in a Root
2. Load Disk Utility and run Repair Permissions
3. Reboot the server (there has to be another option for this?)
4. Log in again and load the Workgroup Manager. Everything should be okay.
If anyone knows a more elegant way to handle this, please post the info as it doesn't seem that great having to do these steps everytime a slight configuration change is made.

I have an Iphone 4s from my work. Until 2 days ago, my iphone would notify me when I got an email or text. Now it does not notify me at all and some times it does not ring at all either. I have not changed any settings at all.

My iphone just randomly stopped notifying me when I got an email, text or voicemail. Sometimes it will not even ring. I confirmed that the volume is turned on and I have not changed any settings at all. My software is up to date. In my job I need to know when I get an email without having to constantly activate the screen or open the email icon.
Does anyone have any suggestions to fix this problem?

First, is the Mute switch activated?
Mute switch is above the volume buttons on the left side of iPhone.
If you see red/orange color the the mute is ON.
Also check Settings > Sounds > for New mail, Text Tone, etc.. have sound entries?
If that's not the case try
Reset: Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. Note: You will not lose any data

Do I need to change any settings to connect my mac book pro to my tv?

Do I need to change any settings on my mac book pro to connect to my tv

Almost certainly, yes. Did you want to know which settings?
Exactly what settings you would need to change, where, and to what would depend on many factors, including at least the following:
* what model MBP you have (which will tell us the connector available),
* what version of Mac OS X it runs (which will tell us the settings available),
* what sort of TV you have (resolution, what connectors it offers, how they are switched, etc.),
* what connecting facilities you have (like wires or an AppleTV),
* how you want to use the TV (primary screen, secondary screen, mirror screen, sole screen),
* whether you want to play audio through the TV,
and even
* where the TV is located with respect to the MBP.
Simple case: New enough MBP to have HDMI output, running a recent OS X, TV new enough to have an available HDMI input, an HDMI cable on hand, using the TV as a secondary screen, and you don't care about how the screen positions relate or where the audio plays. You might be able to get away with default settings on the computer, but you'll still probably have to switch the TV to the HDMI input, and you'll have to drag windows onto the new screen.
