I can't open firefox or install it or do anything, I'm just asked to restart my computer. Please help me!

Something went wrong when I updated to firefox 4 yesterday, when I klick on the icon I am asked to restart the computer. I've done that like ten times now. And I can't uninstall it either, the same window pops up. What shall I do?

There's a version of Firefox here that is designed to work on removable USB storage. This might solve your problem: http://portableapps.com/apps/internet/firefox_portable

Recently I did an update and now can't open iTunes. I get a Runtime Error telling me C Runtime library loaded incorrectly. Please help?

Recently, I did an update on iTunes on my Acer laptop. Now I can't open iTunes & I get a Runtime Error telling me C Runtime library is loaded incorrectly. I have Windows 7 64-bit. Do I need to reinstall iTunes.

Hi sungoddess69,
Thanks for visiting Apple Support Communities.
To resolve this error, I recommend completely removing and reinstalling iTunes and all of its related components using these steps:
Check for .dll files
Go to C:\Program Files (x86)\iTunes and C:\Program Files\iTunes and look for .dll files.
If you find QTMovie.DLL, or any other .dll files, move them to the desktop.
Reboot your computer.
Note: Depending on your operating system, you may only have one of the listed paths.
Uninstall and reinstall iTunes
Uninstall iTunes and all of its related components.
Reboot your computer. If you can't uninstall a piece of Apple software, try using the Microsoft Program Install and Uninstall Utility.
Re-download and reinstall iTunes 11.1.4.
You can find the article with these steps and more information here:
iTunes 11.1.4 for Windows: Unable to install or open

When I turned my computer on in the morning it will not open firefox and now I have no way to go online except using a different computer. Help!!

When ever I click on it all it does is show the loading sign for a second and then nothing. I have tried starting it through start menu and still nothing.

I had the same problem as well and finally worked it out. Maybe it could be related.

FF should open now hopefully.
From there, if your issue is the same, one by one go through add-ons you want installed, making sure to restart after each one to find the one causing issues. If FF doesn't open again, go through the steps for clean install again and don't reinstall that add-on. Once found the culprit(s) and got FF going again without reinstalling those, go about restoring your profile data to get bookmarks and so back. Best to do that last so only have to copy files over once.
That is all I know on this. Really wish I could get an answer to why it is happening as the add-on causing me issues I use constantly, prefer it over others, yet now I can't because want FF to work. Hope this helped.

I can't open a pages document on my air that was saved from my desktop through my idisk - please help!!

Pages is installed on my lap stop, desk top but I guess not on my Air - how can I read that document until I am able to load pages into the AIR - I really need to see and change this document? Thanks.

It's a well known behavior which Jerrold and me described here some weeks ago.
I reported the bug to Apple but it seems that the engineers working upon the AppStore don't know the specs of the different kinds of iWork applications.
They are three kinds :
(1) applications resulting of the trial version + a bought registration code
(2) applications resulting of the instal thru a bought DVD
(3) applications bought thru the AppStore.
The appStore application is able to recognize the case 3.
Given what you wrote, it seems that it recognize case 2.
Given what Jerrold and me reported here, it doesn't recognize case 1.
In the first version, the app was fool enough to treat iWork '08 as bought 09 ones for a task
but make the difference for an other task.
This foolish thing (I'm listening Lester Young) was killed by the late update.
Of course, Jerrold's and my own versions are legal and up to date.

I have to re-start my laptop every time I open Firefox. It never completed the original updated and keeps wanting to restart my computer.

After reading all the other people who have the same issue, I guess as long as it runs when I do a restart, I'll just keep doing that until I see a fix for the problem...

Hello,
Did you try reinstalling Firefox? Download the latest version (33.0.2) for your operating system and language here:
* https://www.mozilla.org/en-US/firefox/all/
Uninstall Firefox in the Control Panel > Programs and Features. Then open Windows Explorer, and delete the folder:
* (32 bit Windows) C:\Program Files\Mozilla Firefox
* (64 bit Windows) C:\Program Files (x86)\Mozilla Firefox
And then reinstall Firefox.
Potentially unrelated: You are using an adblocker that hasn't been updated in over two years, try replacing it with something like [https://addons.mozilla.org/en-US/firefox/addon/adblock-plus/ Adblock Plus].

I can not open Firefox due to a virus. Can I un-install and then re-install Firefox and save my original setup and favorites

I can not open Firefox due to a virus.
When trying to open Firefox, the program directed the computer to shut down, and prevented me from going into Safe mode.
The virus only affected Firefox and rebooting in Safe.
The virus has been scrubbed, but I get the crash report every time I try to open Firefox. Can I install a new version of Firefox and still keep my bookmarks/ How can I rescue my bookmarks.
I am posting this from another computer location.

I used to have a slightly similar problem. Not the Virus problem, but the re-install of Firefox. The solution for this in the future would be for you to install and use FEBE Firefox Environment Backup Extension so you can fully back-up your settings, and other Addons, and Themes etc. that were within your FEBE backed up profile, so you can do the re-install of Firefox and then restore your saved profile that encompasses all of or most of what you presently don't want to loose. You could still do a FULL PROFILE FEBE, and re-install Firefox, and do a FULL PROFILE RESTORE, and if you might no longer have a virus problem after the restore. If so, your in good shape. I would find and run a good quality Anti-Virus scan, and if you wish to try to catch what you might have missed with the new scan I also suggest from www.IOBit.com that you add 2 programs that look to be better at catching problems than most other scan and repair utilities. The programs I suggest you add are called Advanced System Care - presently is version 5, and IOBit Malware Fighter, and one other. Their super powerful Smart Defrag that is faster than most Defrag programs and their is only one other Defrag program that comes close to it's power, and that is Diskepper, and you get Smart Defrag for free, and it's better, and faster than the others in my opinion. ASC Advanced System Care will clean your system and make it run faster specially if you have noticed it is slowing down for one reason or another , and it will do this with less resources than the other programs that you may already be using. The only thing they lack at present is an Anti-Virus portion which would add much more value to the already super programs. Good Luck. Let me know what you think after trying the noted programs. You should be very satisfied of the results.

This issue can be caused by an extension or plugin that isn't working properly.
Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.

* [[Troubleshooting extensions and themes]]

Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
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.
You can initially skip the step to create a new profile, that may not necessary for this issue.

I can not open Firefox. Keep getting the error message "Failed to read the configuration file. Please contact your system administrator." What do I do?

I can not open Firefox. I keep getting the message "Failed to read the configuration file. Please contact your system administrator." I have tried uninstalling Firefox and then reinstalling it but without success. What should I do?

Which Fx version? When you uninstalled Fx, did you reboot computer before reinstall?
Also, check for / delete any leftover files in the Fx programs install folders, before reinstall?
Is your profile in the default location or custom location?
Have you tried creating a new, completely clean profile - to test (then make sure to select that profile to start Fx - from the Profile Manager)? (no addons or plugins installed).
Does the user acct (that Fx fails under) have access ("rights") to all locations - especially for Fx profiles location?

I can't open firefox. i can't send details regarding that to mozilla. i can't restart

it's regarding a problem occuring in Firefox in windows 7. I can't open Firefox in my windows 7 os. i can't restart. send no reports. i tried re installing. it doesn't solve my problem.. eager to here from you. i,m using firefox as my default browser from 2007 n this is 1st time experiencing such a problem..... plz help me....

Hi ragesh,
I'd try starting Firefox in [[Safe Mode]]. If you don't have the issue while all of your add-ons, extensions, and themes are disabled, you can try adding them back in one by one until you find the culprit. You should look at the [https://support.mozilla.org/en-US/kb/Troubleshooting-extensions-themes Extensions and Themes troubleshooting guide ] and the [[Troubleshooting plugins]] article as well.
Hopefully this helps!

Can't open Firefox or Thunderbird after Window 7 update

A Kapersky update and a Windows 7 update clashed and turned off the program. I completed a system restore to two days prior, installed the update successfully, then reinstalled all the Windows 7 updates, 13 of them. Now I can't open Firefox or Thunderbird. The Properties/settings say the the Windows XP update is incomaptible with them. I'm not running XP, so I changed the settings to read Windows 7 for both programs. Still cannot open either one.

you would plug your device into your computer and back it up so you don't loose anything on it. And then in itunes there is a button to click to restore your device. This will erase your device and reinstall ios to factory settings and then from there you can load your backup to your device. This has helped me with any problems i have had with ios7

I can't open Firefox no more, I try clicking on the icon but it doesn't even load anymore.

After some time I realized I can not open Firefox anymore.
I have always used Firefox as my default browser and I really like their features, it's the best browser for me, but for 2 weeks I haven't had the possibility to open it.
I have tried many ways, such as try to open new tab, or try to open new windows, or try to open new private session but none worked. It's impossible to load Firefox. I have been searching on different sites to finally resolve my problem but it didn't help me at all.
I also reinstalled it many times but the same problem.
Thanks in advance and any help will be welcomed.

sorry for the inconvenience caused to you. This may not be a problem with the fire fox instead this may be a problem with your computer.
Plz check your computer for virus mainly "Trojan". download an antivirus and run a full scan and also be updated to latest fire fox version.

Can only open firefox once, have to restart to open more than one browser. can't upload any pictures the box doesn't pop up, my browser settings are diff now

Firefox just changed out of nowhere. I can only open firefox once... I used to have atleast 2 browsers up using them both on different sites, but now I can't have but one firefox browser up (not tabs, but firefox pages) Also when I am trying to upload images on ebay or any other site nothing happens... nothing pops up. I click it over and over and nothing even pops up. This is exactly what happens with the firefox browser in my first question... I can click the firefox icon a million times and nothing comes up. My tabs are all gone and it doesn't show anything like I had before this all changed? Did I reset everything some how? I do not recall clicking anything to go back... I do remember clicking an update because it kept poping up so I did it and that is the last thing I remember before this happened! UGHHH!

As I asked previously are you able to have tabs open as a window by using the right clicking option ?
When you close Firefox you should use
*'''Firefox button -> File -> Exit '''
Are you doing that ?
I suspect what may be happening is Firefox is hanging as it closes down.
* see [[Firefox hangs or is not responding - How to fix#w_firefox-hangs-when-you-quit-it]]_firefox-hangs-when-you-quit-it
* this explains how to check & if necessary kill the process [["Firefox is already running but is not responding" error message - How to fix it#w_end-firefox-processes]]_end-firefox-processes
A related possible problem is that you may have built up many copies of the restore files. These are stored in the Firefox profile. The easiest method of finding the profile location istouse
*use '''Firefox button -> Help -> Troubleshooting Information -> [Show Folder]'''
*see [[Profiles - Where Firefox stores your bookmarks, passwords and other user data]]
You need to look for the files ''sessionstore.js'' and numbered duplicates of that. Delete them.
* see http://kb.mozillazine.org/Firefox_hangs#Multiple_sessionstore.js_files

I can't open firefox or install it or do anything, I'm just asked to restart my computer. Please help me!
