Even after uninstalling, reinstalling Firefox, the Firefox profile folder is empty, and I get the message "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 have followed all the directions I can find, on my computer and Firefox Support. Still, the same message comes up, and "firefox" is not shown in my Windows Task Manager.
What can I do?

Delete the profiles.ini file and let Firefox create a new default profile.

'''Safe Mode'''
You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox SafeMode is a diagnostic mode that disables extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes before starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
See:
'''[[Troubleshooting extensions and themes]]'''
'''[[Troubleshooting plugins]]'''
'''[[Basic Troubleshooting]]'''
If the problem does not occur in Safe-mode then disable all of your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You have to close and restart Firefox after each change via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.

Reinstall iTunes. Make sure you follow the instructions in this support document to the letter. http://support.apple.com/kb/HT1923.
You may have some problems because Apple has not certified that everything works with Windows 8 yet.

After removing malware Firefox is still broken even after uninstall/reinstall, yet other browsers have no problems with links opening multiple unwanted windows.

I removed malware from my new Windows 7 pro 64 bit PC. I have reinstalled Firefox multiple times to try and resolve the problem, even deleting the Mozilla folder from programs on the C drive. Whenever I click on a link on a webpage in Firefox, multiple unwanted tabs and windows open up making Firefox virtually unusable. Resetting Firefox doesn't help. I installed Chrome and do not get these popups. The malware must have caused some damage related to Firefox that will not allow Firefox to function normally even with a fresh install. I would prefer to use Firefox.
I don't recall the name of the malware.

The cause is most likely the preferences file in your profile folder. That file contains your personal settings, so it doesn't get deleted when you reinstall/update Firefox. The reset feature also retains your preferences file.
Instead of doing a mass delete of all your settings, you can try identify the culprits and reset them individually.
# In the [[Awesome Bar - Find your bookmarks, history and tabs when you type in the address bar|Location bar]], type '''about:config''' and press '''Enter'''. The about:config "''This might void your warranty!''" warning page may appear.
# Click '''I'll be careful, I promise!''', to continue to the about:config page.
# Click on the '''Status''' column, to sort your preferences by status, and group all the ''user set'' preferences together. They should appear in bold.
# If you see any preference that look suspicious, just '''right-click''' on it, and select '''Reset'''.
If you're still not sure which ones to reset, you can post most of them here easily. Go to '''Help > Troubleshooting Information''' then click '''Copy text to Clipboard'''. Open a reply to this post, and go to '''Edit > Paste''' to paste the info from your Troubleshooting Information page.

Had a problem with pc & when restarted i have been unable to open firefox even after uninstalling & reinstalling i am on windows vista

Why are some app icons hi-def in the App Store, then pixelated when downloaded? (Even after uninstall/reinstall)? Any way to fix this?

Just as an example, TSN. The icon always appears as hi-def/Retina display in the app store if you search for it or it asks you to update, then when it updates it goes back to being pixelated. I can see if it is an app-specific issue but there are other apps like Bank of America which do the same thing. I don't think it's because they haven't updated the icon because they have, it appears perfect when viewed in the App Store. Uninstall/reinstall did not fix this. Any help you can provide would be greatly appreciated! It may sound minor, but it makes all the difference visually!

How pixelated could the app look like? The only reason why the app icon could look pixelated, is if you are using the iPhone 4 or iPod Touch 4th generation. They obviously have an upscaled resolution, so the apps could not have been upscaled when downloading... I am not sure about this issue...
Like you said, it is a minor issue...

There are some compatibility issues between the latest Flash player and some Firefox add-ons or settings. Could you see whether anything in this article helps: [[Flash 11.3 doesn't load video in Firefox]].

At times when we try to open Firefox we get a message it is already running and have to restart comp . Why is this ?It happens with all users . Thank you

We have gone on our comp after a while and tried to open Firefox . When we do we get a message "Firefox is running close app or restart comp . " Now the thing is I was on it earlier and closed it with the close button . Then say checked mail , or looked at pictures on my comp . Then I would want to use the browser again and when I tried to access it I get that message . Rest assured it had been closed . This issue did not happen until I downloaded Firefox4 . We did not have this problem with the earlier versions of Firefox .

I am trying to download the the 3.6 version and keep getting a message which says corrupted image and not downloaded because of that.

I am a user of firefox but have the 2.0 version and am trying to update to the newer version.

Do you have OS X 10.3.9 or earlier? Firefox 3.6 requires at least OS X 10.4 and you get that error if trying to install it on an earlier version of OS X.
The last version of Firefox that works on OS X 10.2 - 10.3.9 is Firefox 2.0.0.20 available from ftp://ftp.mozilla.org/pub/mozilla.org/firefox/releases/2.0.0.20/mac/en-US/

HT1386 Sync iTunes problem: When I connect the iPhone to our iMac using a USB cord the phone chimes convulsively, the battery icon flashes, and I get a message in iTunes saying "iTunes could not connect to this phone. This device is no longer connected."

It is an iPhone 4s. It used to be set to sync wirelessy but that became annoying and I reset the phone so I could just sync it with the cord. Apparently that was a bad idea.

Hello robh53,
The following article provides some useful troubleshooting steps that can help get your iPhone to cooperate with iTunes.

Firefox always says using old version even after running the upgrade programme. Even after uninstalling & reinstalling? Why?

Every time I open Firefox the message "using old version" appears I have tried uninstalling the program and then reinstalling but no change, When I use Firefox as my browser a message appears to say you are using an old version of Firefox. This is just fustrating what can I do to correct?

Java is not installing into Firefox even after uninstall/reinstall

I need to take a test for a staffing company. They use Java to administer the test. My Firefox does not see Java even though it is installed in my computer. Neither does the test see Java. I have tried uninstalling and reinstalling, turned off my security, and even shut down my computer and restarted it. Any ideas how to get Java in? The testing company had the solution of try another computer.

Nope, still no go. Thanks!

After I close Firefox, if I try to re-open weithin about 1/2 hour, I get a message " Firefox is still running but not responding". How do I fix this?

The question is all there is!!

When I close Firefox by clicking on X in the upper right corner of Vista, Firebox doesn't close and the next time I click on FireFox I get a message that FF is still running but not responding. I use alt,ctlr,delete to use Task Manager to close FF. Why?

The details are in the question. Don't know what else to add.
