Cant start firefox. Uninstall and reinstall don't help

It seems I got a virus that stopped firefox from opening and created ad pop ups on explorer everytime I open a new window. No software detects and corrects the virus so I restored the computer to before the infection but firefox still won't open even after I uninstalled and reinstalled it. I prefer not to use explorer for web browsing. How do I get firefox to open again?

hello SherryHB, please try to run a full scan of your system with alternative security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] and [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] which are specialised in removing adware and browser hijackers...

Firefox crashes several minutes after opening every time I use it. I think Firefox was updated shortly before this started. Uninstalling and reinstalling have not helped. Updating all plug-ins has also had no effect. Would appreciate help fixing this.

Browser starts out working normally but within a few minutes it freezes, stops responing and I have to close it using Task Manager. When I open Task Manager, it shows two Firefox programs running with different icons even though I only opened one window.

iTunes saves out a new copy of the entire library file every time a change is made to the library. This is not new behavior.
The slowdowns I have seen like this have ususally been caused by:
A virus
or
Some anti-virus software is incorrectly interpreting the rewriting of the file and is causing a problem.
Either way, you should definitely update your anti-virus software and definitions to the latest, and run a full scan of your system. If that does not help, you may want to recreate your iTunes library.

Taken at face value, you're having trouble with a QuickTime program file there.
Let's try something relatively simple first. Restart the PC. Now head into your Uninstall a program control panel, select "QuickTime" and then click "Repair".
Does the repair go through okay? If so, are you able to launch iTunes and/or Safari now?

Firefox opens three sided frame when you open it. Uninstalling and reinstalling didn't help.

Firefox 5 cannot load properly. When it loads, it opens a blank frame with three sides showing (left, bottom, right). I say the frame is blank because it shows the blank desktop color inside the frame. Uninstall and reinstall was not successful.
No crash id available as I cannot get an interface.
Using Windows 7 Pro 64-bit. Toshiba laptop.
I have a screenshot available if there is somewhere to post it.
Other browser applications work with no problems.

-> Start Firefox in Safe Mode by Holding down SHIFT key while Starting Firefox
-> As an alternative method, press '''Win + R''' keys and enter one of the following in the Windows Run box:
firefox -safe-mode
OR
"C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode
-> Firefox Safe Mode window will appear -> DON'T SELECT ANY OPTIONS, just click '''Continue in Safe Mode'''
Check and tell if its working.

Hello,
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.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

I cannot get Firefox to come up. It says it is running but cannot find it. I have uninstalled and reinstalled. Please help.

When I try to bring Firefox up it does not show that it is. If I shut my computer down it will come up the first time and as long as I leave it open it is okay. When I log out it does not come back up the next time. I am not having trouble with Chrome or Explorer.

The Firefox Home app for iOS is not the Firefox browser but rather for to synce with your desktop Firefox to have your Firefox desktop history, bookmarks and open tabs on your iPhone/iPad.

We have no plans to release the full Firefox browser for iOS. The iOS SDK agreement requires apps to use Apple's own JavaScript engine (or none at all, like Opera Mini which downloads pre-rendered pages from Opera's servers and cannot run JavaScript code in the client). Because of this, we have no supported way to distribute Firefox's rendering and JavaScript engine to iPhone users.

That's the error messages I get when I try to open the New installed iTunes 11.1.4. Right now there is no iTunes on any of my PCs. Installed but will not open. Please Help.Thanks.

Can someone please direct me how to properly uninstall and reinstall???

I had a previous post as well but I just want a fresh start on uninstalling and reinstalling. When I followed the steps and then opened itunes it had my previous library there even after I deleted the itunes folder from program files.
I've had Itunes forever now and it's been fine. With this last upgrade, it's created some problems. Half of my new playlists created have disappeared. The music is still there in the library, just the playlists are gone which was enough to fill a 60 gb ipod. Itunes now reads at the bottom I have 1022 GB of music - my hard drive is 250gb so that's obviously incorrect. My iphone will not recognize my calendar or my contacts in Office 2003 with all updates - so basically it's hosed. Someone had given me a link to uninstall it which I did. I restarted. Then I uninstalled apple mobile something or other and restarted. Then I deleted the itunes folder from program files emptied recycle bin and then restarted. I then proceeded to re-download and install itunes. I went through the hour process of uninstall and restart then install. I get everything finished and open itunes expecting to see a fresh clean slate and it's exactly the same. What did I do wrong since I followed these instructions at the bottom for uninstalling http://docs.info.apple.com/article.html?artnum=305845
I need help. I figure at this point I'll take my losses with my playlists I have spent years building just to have everything working again. I appreciate any help you can give.

Connect to any computer that has iTunes loaded. The following will work for everything EXCEPT music that was obtained from some place other than the iTunes Music Store. If that is your situation, post back before you proceed.
Restore, if iTunes will let you. Everything except the password will be restored. Connect via cable to the computer that you use for sync. Be forewarned that it takes a long time. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here.
If things go wrong and you lose your apps, music, movies, etc. this is "Plan B."

I want my old iTunes back, I am sick of uninstalling and reinstalling this new version. I just need my apps for my new iPhone6

how can I just get my old itunes back. I am not going to continue uninstalling and reinstalling the new version. I had it on my computer, and for some reason it crashed and I started this commotion. I have uninstalled and reinstalled with the help of Fix It and advice from many people. Every time I get a new error. Sick to death of it. I only need it to sync my apps to my phone and to use iCloud.
If anyone can get me back to some other version that I can use, I would really appreciate it.
I have Windows 7 on my PC

If you really want to roll back to 11.4 uninstall all iTunes/Apple components, restore the pre-upgrade version of the library as described inEmpty/corrupt iTunes library after upgrade/crash, then download and install from one of these direct links:
iTunes 11.4.0.18 for Windows (32-bit) - iTunesSetup.exe (2014-09-09)
iTunes 11.4.0.18 for Windows (64-bit) - iTunes64Setup.exe (2014-09-09)
If you have trouble uninstalling or reinstalling see Troubleshooting issues with iTunes for Windows updates. The same tip should help you get iTunes 12 installed properly if you want to give it a try.

Hello Susan.
It's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] (don't forget to select ''Disable all add-ons'' when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and themes and [https://support.mozilla.com/en-US/kb/Troubleshooting+plugins this one] for plugins.
If you need support for one of your add-ons, you'll have to contact its author.
If the problem is not disappears when all add-ons are disabled, please tell me, so we can work from there.

When I try to start Firefox, I get a message that it is already running but not responding and I can't run another Firefox at the same time. I uninstalled and reinstalled. No change. Tried various other suggestions. Help!!

When I try to start Firefox, I get a message that it is already running, but not responding and that I should close it before trying to run another Firefox. But I cannot find a way to close Firefox program that is not running as far as I can see. I tried uninstalling and reinstalling Firefox, but that did not work. I've tried various other things, but no luck. I thought programs should stop when the computer is turned off, but that didn't work either.

How are you opening the Profile Manager?

Sounds that Firefox is still or already running.<br />

Firefox 3.6.8 will not start. I have to go to safe start, click reset to default, ok, then the shutdown box appears, I click cancel and it will open. I have rest profile, uninstalled and reinstalled, clicked alll he boxes on safe start, tried an older version need help. in English
== This happened ==
Every time Firefox opened
== either after I last updated to 3.6.6 or .7 or reset my inernet exploerer values to default

I had same problem where Firefox 3.6.8 would not start or open. Spent many hours trying different things to fix it. Uninstall of previous version and reinstall did not make any difference. Finally, after uninstalling Firefox, I searched for Firefox folders and files on my computer, deleted and removed all Firefox folders and files - deleted anything and everything related to Firefox so that it will be as if I was going to download Firefox for the first time ever. Then, using another browser, I downloaded Firefox 3.6.8 and installed it. It could be that some Add-Ons or something else from the older version of Firefox or profile was interfering with the new one. It was easier to delete remove everything and install all over again clean than to figure out which part was causing the problem.
Keep in mind, when you delete all Firefox folders and files from your computer, you are deleting all your bookmarks and all your Add-ons. If you want to keep those bookmarks, you might want to save the URLs someplace safe to bookmark them again before deleting them. You need to re-install the Add-ons also. Upon installation, it asks if you want to import bookmarks and settings from another browser or settings you might have. I imported them from my other browser. Now, Firefox works. I also installed up-to-date Add-ons.
I hope this helps. Always keep more than one browser functioning on your computer, just in case one fails.

I have firefox 3.6 installed in my laptop but for past few days i have been unable to start it, I uninstalled firefox once and reinstalled it but nothing positive haapened.

I am using windows 7. As I mentioned in the question that firefox has stopped working for last few days though chrome is working fine but as i prefer firefox so i need help. I tried all sort of permutation like uninstalling and reinstalling it and then installing the other versions but nothing worked.

I have already tried removing firefox from my firewall. Even when I do that, my firewall doesn't detect firefox and prompt me to add it. And when I manually add it, it still doesn't work anyways. I've already tried the link as well, but it has been unhelpful. :/
I'm not sure if it matters, but a few weeks before this, I did download Microsoft Security Essentials.

HT1923 i couldn't open itunes so it suggested i uninstall and reinstall. when i go to reinstall a message comes up that i don't have sufficient privileges to start system services.

i found that i couldn't open itunes on my home computer so the website suggested i uninstall and reinstall the program. i uninstalled it then tried to reinstall and an error box comes up that says to verify i have sufficient privileges to start system services. I'm not sure what this means or how to fix it so i can finish the installation process.

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall move on to the next item)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

I selected "update all" to update my apps, entered my ID and they all went to "waiting" and none of them started updating. Tried shutting down (several times), it was plugged in, I closed all open apps...tried uninstalling and reinstalling 1 app and it still is waiting? Thoughts?

See if any of these suggestions help you. They have worked for others in the past but YMMV.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
Make sure that you do not have a stalled download in iTunes - a song or podcast .... if you have a download in there that did not finish, complete that one first. Only one thing can download at a time on the iPad so that could be what is causing the problem.
If that doesn't work - sign out of your account, restart the iPad and then sign in again.
Settings>iTunes & App Store>Apple ID. Tap your ID and sign out. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Go back to Settings>iTunes & App Store>Sign in and then try to update again. Tap one waiting icon only if necessary to start the download stream.
You can also try deleting the waiting icons - tap and hold down on an icon until it wiggles - the tap the X on the icon to delete it. Then try to download again.
You can try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your device settings again.... All of the settings in the settings app will have to be re-entered.
If all else fails, download the updates or the apps in iTunes on your computer and then sync the content to your iPad.
