When I click on Firefox I get a message saying Firefox is already running, that I need to close Firefox or restart my computer and it still will not start, Why?

Firefox was working great until at least 3 persons were on my computer over the weekend. Now, when I want to open Firefox to go to the internet I get a message telling me that it is already running, that I need to close it down and if that doesn't work I should restart my computer. I have done all this, turned the computer off and back on many times, but I still get the same message. I do not know what the other people may have done when they were using my computer.

See these posts about the same problem:

On a frequent basis when I go to open Firefox, I get a message saying it is already running and can't be opened. This happens on two of my XP computers. The only way I can open it is to restart the computer.

The details are in the question. I have to restart the computer to get Firefox to work a few times a week

I will try to always use "file - exit" to close it to see if that fixes the problem, but with older versions, X ing out worked OK all the time. Something may have changed with this later version.
Thank you

Often i try open firefox but I ge a message saying it's already running to wait until it shuts down or restart my computer??

for example I've closed Firefox earlier, but when I go to re open it I get the message that it is running

This has happened to me a couple of times many months ago. I either kill the task using task manager; or I just re-boot my pc. sometimes just best to completely shut down your pc, unplug the power for a few minutes, and restart. If you're like me and leave your pc in sleep mode for days or weeks at a time, a lot build up, which may cause some programs to hand for quite a while.

On my Ipad I seem to be having a problem when trying to play YouTube videos embedded on Facebook.
When I click the links, I get a message saying: "Flash Player upgrade required."
and under it, it says, "You need to download and install the lastes version of Adobe Flash Player to view this content"
and also a green button saying "Get Flash Player"
I get this if using chrome or safari .
I can go direct to YouTube it just works.

The Facebook link to the video is accessing an Adobe Flash video. Unfortunately, no iOS devices can play flash.

Is your "home computer" the same as your laptop or are these two different machines?

I keep getting the msg 'Firefox is already running...need to close out or restart...'; can't get it to reopen a window w/o restarting

During any session at my computer if I mistakenly close out Firefox and then need to reopen, I get the message that "Firefox is already running...need to close current (window)...or restart your system.." No matter what I do, I can't seem to reopen a Firefox browser window without restarting my computer. The same problem occurs when i leave my computer in Sleep mode for a few hours, and return for another session. I try to double click the desktop icon to open Firefox, and get the same message. Restarting my computer is the only way I am able to open a Firefox window.

When I close Firefox and then come back to it later a box comes up that says it's already running. It says to close Firefox first but when I hit close nothing happens and the box comes up again. I have to shut down my computer and restart to get into Firefox again. If I can't get this fixed I will start using someone else. Someone told me a way to close Firefox but I forgot what they said.

Every time Firefox opened

Hello Brian.
You don't need to restart your computer to open Firefox again: you just need to close it manually through your application manager (CTRL+SHIFT+ESC in Processes tab). Anyway, hopefully this support article is what you need:
http://support.mozilla.com/en-US/kb/Firefox+hangs
What's probably happening is that you may be 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 coming from 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] and select ''Disable all add-ons''. 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 theme. You can troubleshoot plugins the same way.
If you want support for one of your add-ons, you'll need to contact its author.

I have firefox on the server. When I click on it, I get a message saying that an upgrade canot be done as other Firefox may be running. There is no other Firefox running. And then the browser opens ups

It actually says that Firefox is already running but not responding and the other window needs to be closed. Cannot find any other window running.
Only happens on the server.
OK on the PC desktop

I have similar problem on Win XP if i have used Firefox 4 but have closed it, then try to open Firefox again; it will give me that error message.
Message says to reboot but that is not always possible if I am in the middle of another program.
I found that if you open the windows task manager (ctrl + alt+ del) >>processes tab
highlight the "image name" firefox.exe and click end process.
Firefox will then restart normally.

Firefox crashes then when I try to reopen it I get a message saying it is already open and must be closed. It is not open and I cannot close it and have to reboot. It is very annoying as it happens often.

Firefox will close unexpectedly then when I try to open it I get a message saying it is already open and I must close it first. I cannot find it open anywhere and then I must reboot to open Firefox again.

You would get the redemption code, or perhaps even the serial number, from whomever you purchased the software from, apparently Amazon, so talk to them. This wouldn’t be the first time they’ve sold something that didn’t have all the numbers needed to license it.
A redemption code is something that is usually on the inner disc packaging if you purchase the media in a box, and there is a barcode on the outside of the packaging that must be scanned at the checkout register to activate the hidden inner code so you can redeem it at home on that website. This is what happens if you buy PSE from a brick-and-mortar store like Best Buy. I don’t’ know what happens if you purchase the downloaded version as I have never done that.
A redemption code is 24-digits of letters and numbers that you enter into a website to get a serial number, once and only once. The serial number of only 24-digits, no letters, is what you enter into the software during the install or when you run it and it asks if you want to register or run in a trial mode—whatever the exact phrasing is.
In any case it sounds like you don’t have either a redemption code or serial number—although perhaps something is listed on the purchase confirmation or your account online at Amazon or even in an e-mail from Amazon.

I have just downloaded firefox 3.6.11 and adobe flashplayer update and adobe reader update. Now I cannot get firefox to open. I have tried removing Firefox but when I try to do that it says that I need to close firefox - but of course it is not open. I have waited a long time but nothing has happened so I am getting desperate Thanks -- Jerry

Do a clean (re)install:
* 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.
* Don't remove personal data when uninstalling.
* 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.
