Applications Panel is blank even after complete uninstall and reinstall.

I have a client who is having an odd issue. His applications panel under options is completely blank. He is having issues with opening downloaded files and viewing videos in the browser window. I have uninstalled firefox, removed his profile, removed all folders associated with firefox. Removed the mozilla/firefox folders in the appdata folders. Followed the instructions for resetting download actions here: http://kb.mozillazine.org/File_types_and_download_actions#Resetting_download_actions and here: http://kb.mozillazine.org/Download_Actions_list_is_empty . I have also reset firefox using the troubleshooting tools.
Nothing seems to work except for running Firefox under a new windows profile which is an unacceptable solution.
Is there anything else I can try. My client said he used to use MozBackup to backup/restore his FF profile and settings. I have searched for issues relating to that program but turned up nothing.

Sorry, I seemed to have overlooked that in the second link.
If there are any extensions (I don't see any in the System Details you copied over - if that is the case then please skip down to the next section), you can try [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] to see if that fixes it. Safe mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes). If the dialog appears fine in Safe Mode, please follow the article [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] - if you have a lot of extensions it might be better to disable half of the extensions to see if that fixes the problem (if it does, the problematic extension is in the half you disabled, otherwise it is in the half that is still enabled).
Since Firefox works fine in a new profile, an alternative could be to transfer all of the important data (bookmarks, passwords, etc.) to the new profile. Please see [[Back up and restore information in Firefox profiles]], or [[Recovering important data from an old profile]] for more information on what to transfer. Be sure not to copy over the ''mimeTypes.rdf'' file in case that file corrupts the new profile.
You can set that new profile to always run by checking "Use the selected profile without asking at startup" in the profile manager. Please see [[Use the Profile Manager to create and remove Firefox profiles]] if you are not sure how to access this feature.

Firefox states it is already running yet won't open even after I uninstalled and reinstalled

Hi,
I was having problems with Mozilla when I'd go to Facebook it would show the page but within seconds I would get check6 (can't remember the rest) error page.
So I went to help, restart Firefox. It was at this for about an hour and I knew there was a problem so chose to end process in task manager.
Since then I haven't been able to open Firefox:
"Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system".
I uninstalled Firefox using Revo Uninstaller and deleted all leftover files, restarted my computer and installed Firefox, but the problem still remains.
I tried looking through previous questions and noticed I do no have a profile folder which may be needed to delete a lock file....
Any help much appreciated! thanks

I had this problem yesterday, actually. You can solve it, but you will lose all firefox data you didn't back up. Then again, because you already tried uninstalling and reinstalling, I assume this isn't an issue.
Assuming you've installed windows on the C drive:
Go to C://Users/yourname/AppData
If you cant find it, go to your display settings (I hope I translated this correct; I use the Dutch version of Windows) and make sure that hidden files and filders are not being... well, hidden. Shocking plottwist, I know.
If all goes well, you should now see three folders named Local, Localrow and Roaming.
Now go to Roaming > Mozilla > Firefox and delete everything thats in there. Now you have an empty FireFox folder, which will force Firefox to start up as if it was never installed before.
Done! :)
P.S. Now that you have a fresh new install, save yourself a lot of future pain and install [https://addons.mozilla.org/firefox/addon/xmarks-sync Xmarks] for your bookmarks and [https://addons.mozilla.org/firefox/addon/lastpass-password-manager LastPass] for your passwords. These add-ons will keep your data safely on their servers, where it is yours to backup and download anywhere in the world.
Also, if you have about three milion add-ons and personas/themes and you don't want to hunt hem down again everytime you reïnstall Windows or buy a new system, get [https://addons.mozilla.org/firefox/addon/febe FEBE] to save a copy of them for you. And if you really want to backup like a pro, install [https://www.dropbox.com/ DropBox] (not an addon) and tell FEBE to store its files there, so you can still retrieve them if your house happens to burn down.
Xmarks, LastPass and FEBE: the holy trinity of Firefox backups :P

Firefox won't do the Master Password thing on mynew laptop. I have to eneter P/W's on each site i vist. it has worked fine on my PC, but even after i uninstall and reinstall Firefox, it still doesn't work.

i used to run the Norton password feature (it came w/ the new laptop) but now that i switched to McAfee, it doesn't recognize when i go to different sites. I've set up everything in the Mozilla menu (Tools, Options, Security, etc). it doesn't ask me of it want it to remember the password when log into Yahoo/Google/Facebook/etc)
i really like this feature and would like to figre out how to make it work. it works fine on my PC, by the way, just not on my laptop

I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

New itunes wont run in windows 7 64 bit even after full uninstall and reinstall

after the new itunes 2.2 came out i have been unable to get it to open or run i have fully uninstalled all elements and reinstalled and still it wont run

it just ask permision to run program then
... that's interesting. Is that one of those User Account Control type messages?
I'd like to see that screen if possible, stew. Could you take a screenshot of that permission message screen (Hold down Alt and press the PrtSc key), paste it into a Paint document (or similar image editor), and save the file. Then reply here, click the wee camera icon, do a Choose file, browse to the file, click "Open file", then click "Insert Image".

Firefox keeps telling me to upgrade. Even after complete uninstall and installing the newest version. Also, each time I restart my desktop I have to acknowledge about 12 add-ons. After that all works fine. Even when I restart Firefox.

I already tried uninstalling all add ons and then reinstall them again. Can the problem be related to the Siphon add on (which I no longer use)?

You posted your troubleshooting information in another thread ([[/questions/907656]]) that seems to indicate that you use or have used that profile folder with a lot of Firefox versions and are overriding the compatibility check (extensions.checkCompatibility.12.0).
You need to use a separate profile for each Firefox version if you want to use multiple Firefox versions.

Firefox will not start up even after I uninstalled and reinstalled.

I even did a system restore to back before the problem started in case it was a OS problem. I did notice a firfox safemode file in system startup which was not the location I installed to. There are icons on my desktop and start menu. I recently switched to Panda Secuity so I uninstalled that and switched back to System Mechanic [used for several years, worked fine with Firefox] to see if it made a difference, it did not. Any help or suggestions greatly apprciated.

One of your add-ons might be the culprit. Try running Firefox in [[Safe Mode]]. If that solves the problem, see [[Troubleshooting extensions and themes]] and possibly [[Troubleshooting plugins]]

Images are not loading/not loading completely, persona previews no longer works with scrollover - even after complete uninstall/reinstall, but images work in IE - suggestions on how to fix this??

Images on websites often do not load or load incorrectly/incompletely load even after refreshing page and clearing caches. Often have to "clear recent history" 5 or 6 times within a single firefox session to get working links, images, completely loaded pages. The persona previews no longer do an "automatic preview" with a scroll over and now i no longer even get an image on the page to scroll over (images are just NOT THERE). I have done the safe mode test, have updated everything suggested, have checked all add ons as suggested in the troubleshooting guide and NOTHING shows as being a problem. I even did a complete uninstall and reinstall and it is STILL not working. Worried that it was an issue with my computer, i checked the pages in IE, and they worked PERFECTLY. I am uncertain what to do now. It started as a problem once or twice a week, and now it is EVERY time i bring up Firefox. Help?

the second article did offer a suggestion that SEEMS to have helped ::crosses fingers:: - an about:config, resetting of the preferences for images. we'll see how long it lasts. THANK YOU SO MUCH for the suggestion, the article wasn't one i'd found while searching for troubleshooting info.
Java script is enabled, but the persona's stuff still isn't working. dang it. WELL, one thing seems to work now, at least. thank you.

After successful installation of iTunes 10.6.1, iTunes will not open. Tried complete uninstall and reinstall, still not working. Cannot sync iPad or access iTunes at all. Any suggestions?

After successfully installing the iTunes upgrade to 10.6.1, Now I cannot open and access itunes. I have tried a complete uninstall and reinstall and it is still not working. I have looked through many support communities for answers. I added an iPad 2 almost a year ago and all was fine until my upgrade to the "cloud services" and upgrade to new version. I have been without iTunes on my PC for a month. Any suggestions on how to resolve this issue?

I too have only recently encountered this problem. I have been able to burn disks before but it keeps making all these weird sounds. It might be a hardware problem but the fact that everything else that uses a disk works I doubt it.

Today, 01/23/2014, I tried updating iTunes, as I got a messsage that update was available. The update did not download correctly I got the message to uninstall iTunes and reinstall it.

Try reinstalling the program fo fix. then I got the message, iTunes was not installed correctly. Please reinstall iTunes. Error 7 (windows error 126) I have had iTunes since I purchased the iphone in 2012. I have only updated the product since then until today when I did the uninstall ans reinstall as stated in above directions. I am not sure what is different now. please help

I had this problem as well but found the soultion on another post from turingtest2 - it worked for me:
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
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or by right-clicking the downloaded installer and selectingRun as Administrator.

Firefox stopped working and won't install after I uninstall and reinstall.

Firefox stopped working one day. It would not load anything. I followed the directions and completely uninstalled and then reinstalled Firefox. It goes through the process and then says Firefox will load momentarily. It never does. Also, what do you have against hiring people to answer questions in person?

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Just installed itunes but when i try to open it this error message pops up: "apple application required" then it suggests uninstalling and reinstalling which i've done a few times but nothing works

When you say you have tried everything, it would help if you told us what you have tried to avoid duplication.
When you installed iTunes did you get any error messages?
Anyway, on the face of it it may be worth trying a separate install of Apple application support.
Uninstall iTunes again. Now open Apple Software update, assuming it is working.
It should offer to download iTunes. Don't do it yet, go to the Tools menu and select Download only.
Then download iTunes. Then go to the tools menu again and select Open download folder and you should see a collection of six files.
Before going on, can you get to this stage OK?
One further thing I would like you to check, are you ahving any problems with Windows updates? Could you check in Windows Update to see if there are any failures.

Previously running CS4 won't open, even after script clean and reinstall

I can't get in!....
Seems like a license issue.
After trying all (7) of the fixes in kb405970 recommended by Adobe tech support, I was unable to get access to my previously working CS4 Production Suite products. I removed the entire program and ran CS4 Clean Script for Macintosh, then reinstalled Production Suite.
Now, when I try to get into any of the products, i get a registration screen that accepts my VALID and REGISTERED (from the Adobe Registration site) CS4 Prod Suite serial number, and NOTHING happens. No programs open.I can't get any response from Adobe tech support for the last 10 days. Case has been open since October 18. I'm just diving into asking for help in a forum.
HELP! Please

After restore , uninstall, and reinstall, firefox still crashes on startup on Mac

I had about 20-30 tabs open, but that has never been an issue. Firefox was slow to load an active page, and suggested restore. I clicked restore and tried to reopen firefox. the main page came up and then crashed. I tried again and it crashed again. I opened in safe mode, and it crashed. I uninstalled from the app folder, opened opera to download and reinstall, and it still crashed. That was two days ago. I cleaned everything off the computer related to firefox in the spotlight search, and uninstalled and reinstalled. It opened for a little longer, and crashed again.

How can i restore my e-mails (especially a saved message file) after i uninstall and reinstall

I have picked up some kind of bug in my e-mail program. I have used malwarebyte and Norton and I think it is cleared up. the problem is that I now cannot send e-mails. Comcast tells me the problem is in thunderbird and I should uninstall and reinstall. I have a "saved message file" I do not want to lose. where is this file and how can I save it. thanks.

Please tell comcast from me that they are idiots.
The suggestion to uninstall and reinstall is about as likely to fix your issue as dropping the device in the bath.
So lets look at this. I assume you get some sort of error message, what is it? Exactly please.
Personally I would be putting money on Nortons being the issue as it has a very long standing habit of making mail sending and receiving difficult.
Check in the Nortons firewall that Thunderbird has full access to the internet. Automatic is not enough. Then disable all email scanning ion Nortons, reboot your computer and try sending again. Any better? A new error message?

Applications Panel is blank even after complete uninstall and reinstall.
