New Firefox 6.0 will not install, says "close Firefox" when not open

I'm trying to install Firefox 6.0. It will not run and keeps telling me to "close Firefox" even though I do not have it running. Does it see itself running? Is there a glitch?

Must be the "hang at exit" problem. <br /><br />

I have tried uninstalling and reinstalling Firefox several times. Every time I try to open Firefox I get an error message saying "Close Firefox"," A copy of Firefox is already open. Only one copy of Firefox can be open at a time."

I uninstall Firefox, then reinstall Firefox, try to open Firefox, and get an error message in a popup box saying,
"Close Firefox"
"A copy of Firefox is already open. Only one copy of Firefox can be open at a time."

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Why does Flash install completion close tabs when re-opening Safari?

Here is a link to the last time this was brought to the attention of the Adobe team on 9/11/2014: Safari Browser Tab Cleared After Flash Installation
Is this something that will be fixed soon or does Adobe just not care? It can be very time consuming to track down tabs that were left open for various reasons. Please fix this and have Safari re-open with tabs that were open before a Flash player update.

It's something that we're aware of, but it's not trivial to solve. It's definitely on our radar, and we apologize for the inconvenience.

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.

Firefox will not open, and I can't uninstall/reinstall because it says "close Firefox first"

After running Ccleaner today (and it asked me to "close Firefox or the internet cache will not be cleared", but Firefox was closed or so I think), I can't open Firefox at all; double-clicking the Firefox icon on the desktop does nothing, and no other way works. I thought of doing an uninstall/reinstall but it says "close Firefox first" - but for me it is truly closed.

See if you can Force Quit things holding CMD+Option+esc keys.

When i try to update to firefox 3.6 it says close firefox but its not running

when i try to update my firefox to firefox 3.6 it will get to installation wizard and it will say close firefox but it isint running and im getting tired of it i need help

If you have problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox program and save the DMG file to the desktop
* Firefox 5.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Trash the current Firefox application to do a clean (re-)install
* Install the new version that you have downloaded
Your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks and other personal data.

Try this...
Triple click anywhere in the line below to select it and press Ctrl+C to copy it.
cmd /k netsh winsock reset
Press the WinLogoKey+R to open the run dialog, then Ctrl+V to paste, then press enter/return.
You should get something similar to this:
Reboot the computer and the problem should be resolved.
If it doesn't work then perhaps a full tear down and rebuild of iTunes will fix things. See Troubleshooting issues with iTunes for Windows updates for details.

Hi
And without info - it's near to impossibly to help. Try my general troubleshooting note:
Troubleshooting note
When iMovie doesn't work as intended this can be due to a lot of reasons
iMovie Pref files got corrupted - trash it/they and iMovie makes new and error free one's
problem in iMovie Cache folder - trash Cache.mov and Cache.plist
Creating a new User-Account and log into this
This forces iMovie to create all pref. and cache files new and error free
Event or Project got corrupted - try to make a copy and repair
a Codec is used that doesn't work (even though iMovie and/or iDVD tries to / they fail in the end)
version miss match of QuickTime Player / iMovie / iDVD
preferences are wrong - Repair Preferences
other hard disk problem - Repair Hard Disk (Disk Util tool - but start Mac from ext HD or DVD)
External hard disks - MUST BE - Mac OS Extended (hfs) formatted to work with Video
( UNIX/DOS/FAT32/Mac OS Exchange - works for most other things - but not for Video )
USB-flash-memories - usually do not work
Net-work connected hard disks - usually do not work (most often not fast enough and WRONGLY FORMATTES as DOS etc)
iPhoto Library got problems - let iPhoto select another one or repair it. Re-build this first then try to re-start iMovie. When iMovie starts-up it first look trough this iPhoto library and if faulty it all Halt’s.
This You do by
First - close iPhoto
Secondly - on start up of iPhoto - Keep {cmd and alt-keys down}
Thirdly - now select all five options presented
THEN - WAIT a long long time (>20 hours are not strange)
free space on Start-Up (Mac OS) hard disk to low (<1Gb) - I never go under 25Gb free space for SD-Video (4-5 times more for HD)
external devices interferes - turn off Mac - disconnect all of them and - Start up again and re-try
GarageBand fix - start GB - play a few notes - Close it again and now try iMovie
Screen must be set to million-colors
Third-party plug-ins doesn't work OK
Run "Cache Out X", clear out all caches and restarts the Mac
Let Your Mac be turned on during one night. At about midnight there is a set of maintenance programs that runs and tidying up. This might help
Turn off Your Mac - and disconnect Mains - for about 20-30 minutes - at least this resets the FireWire port.
In QuickTime - DivX, 3ivx codec, Flip4Mac, Perian etc - might be problematic - temporarily move them out and re-try
(I deleted the file "3ivxVideoCodec.component" located in Mac HD/Library/Quicktime and this resolved my issue.)

I solved the problem by removing the file: 3ivxVideoCodec.component. after that, up-dated iMovie runs ok.
Last resort: Trash all of iMovie and re-install it

No, it does not. It transfers purchases from the iDevice to the computer. The computer must be authorized for the Apple ID that the content was acquired with.

Are they selected to sync? Is Manually Manage content on the device selected?

What does that have to do with syncing content to the device? FYI, nothing.

When i was updating i phone version 4 from Itunes. It got stuck in middle of updating, after uninstall the version3. But new version was not installed. Now itunes is not detecting the iphone and iphone is also not working and showing connection cable with itunes. Pls help..

Check your system for possible Malware. But you have to do it in WIndows Safe Mode.
(Do not use your own Anti-virus to SCAN)
Start your computer in "Safe mode with networking", go to this link download a free version of Malwarebyte.
http://www.malwarebytes.org/products/malwarebytes_free
Install and perform update immediately, then do a full SCAN. Remove malware if it indeed finds any. Restart computer to regular windows to let Malwarebyte complete the removal.
To start your computer in safe mode
Press and hold the F8 key as your computer starts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you'll need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.
On the Advanced Boot Options screen, use the arrow keys to highlight the "safe mode with networking" option, and then press Enter. Log on to your computer with a user account that has administrator rights.
When your computer is in safe mode, you'll see the words Safe Mode in the corners of your screen. To exit safe mode, restart your computer and let Windows start normally.

Can not install the latest firefox. It tells me that its running so i can not install it. Mean while it's closed. I have check everything that i can to make sure it is closed but still have the same issue.

Cant not install the latest Firefox.

Do a clean (re)install and delete the Firefox program folder.
* Download a fresh Firefox copy and save the file to the desktop.
* Firefox 8.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Uninstall your current Firefox version.
* Do not remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.
* Remove the Firefox program folder before installing that newly downloaded 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.
Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

I cannot open Firefox so decided to try and uninstall and reinstall, when the uninstall or install wizard starts I keep getting "Firefox must be closed to proceed, please close Firefox to continue" but i do not have Firefox open at all.

Originally I was having a problem with Firefox locking up everytime I went to a website and tried to X out of it, there would be no response. Or the little box would come up with the question on whether i wanted to Quit or close tabs, I would make my choice but nothing would happen. Then yesterday I couldnt open Firefox at all, so I tried to uninstall and also reinstall but keep getting the error message "Firefox must be closed to proceed, please close Firefox" But i do not have it running anywhere, it does show in my downloaded programes, but I cant do anything with it. I am running Windows 7 on a Dell Inspiron

When I open Nightly all I get is a small black window that says close firefox

I have Nightly installed on a laptop using Windows 7. I have been using it for nearly a year. This afternoon, when I tried to open Nightly, all I got was a small black window saying "close firefox." I used Chrome to get on the web, downloaded the most recent version of Nightly and tried to open it. Same thing happened. How do I get Nightly back?

Any particular reason that you use the ''(sometimes unstable)'' Nightly version, rather than a stable Release version of Firefox?
Nightly isn't intended to be "used", but rather for users to help the Mozilla developers by "testing" each new build and then reporting any Bugs or 'glitches' they may find. Nightly is between 12 and 18 weeks from the release of a new version of Firefox - the Alpha 1 stage which is 6 weeks in duration.
