Firefox suddenly disappears, but still running

Firefox suddenly disappears from the screen and the icon too, while it is still running. When I try to reopen it, a window pops up to warn that Firefox is still running. I have to close the session from Task Manager (End Process firefox.exe from Processes tab). This happens only on my account. I do not experience this problem on a different account.
I have XP sp3.

Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do not click the Reset button on the Safe mode start window or otherwise make changes.

Firefox 29 closing but still running in background

I've tried most of the solutions but all to no avail. I've noticed that I've two profiles marked as default, one is 8mb and the other 147mb if I delete the smaller one would this cure the problem?

Which profile is Firefox currently using?
You can use this button to go to the currently used Firefox profile folder:
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
Use "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit) to close Firefox if you are currently doing that by clicking the close X on the Firefox title bar.
Try to set the Boolean pref network.seer.enabled to false on the about:config page.

how to get artists tab back?

Hi Gary gar,
Welcome to the Apple Support Communities!
It sounds like the options at the bottom of the Music application may have been edited. You can click the More section on the far right, then choose Edit in the top right. You can then drag any options you want to that bottom bar and rearrange them.

Since installing yosemite my computer/screen blacks out, but still running

Since installing yosemite last week, my computer/screen blacks out, but still running. I have since rebooted everything, started from scratch and utilizing my external drive transferred all files/apps back. Did not help, in fact it is getting worse. Computer screen blacks out every 5 min or so and have to power up again. Also, continue to get Java message updates even after all have been updated over and over again. Any suggestions? Thanks!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

In firefox 4 RC, some addons installed suddenly disappear, but checking the profile, some of the missing addons related files are still here, how to make the addons back?

I use firefox 4 form beta 9 to RC (zh) now and there are also firefox 3.6 installed in computer. One day when I open Fx 4 RC, some (actually a lot but not all) of the adoons just disappear. When I check on about:addons page, some addons installed do not appear in the list.
The addons '''REMAINED''' including:
* addons I already used in Fx 3.6 (like webmail notifie , xmarks)
* ''addons only can use in Fx 4'' (like Open Web Apps for Firefox).
The addons '''DISAPPEARED''' including:
* addons I already used in Fx 3.6 (like yoono)
* '' addons installed when using Fx 4'' (like updatescanner, Thumbnail Zoom).
But when I check the profile(by Help > Troubleshooting Information>Open Containing Folder) , some (not sure is it all) of the missing addons related files are still here [lucky], so any one know how to make the missing addons back?
Some more details:
* This happened when i use RC for already a few days and keep on even i restart Fx and windows.
* The bookmarks, history, search engine and even themes and icon setting are still here. [ I only sync bookmarks but not history for both xmarks and firefox sync.]
* This addons are really '''disappeared''' but not disable only!
* This number of addons missed, as i remember, at least 30, should be more than that number bacause some of them are installed but in disable mode.
* I try to install back one of the addons - Stylish, the installed code are still here.
* It is nearly an impossible mission to install every missing addons again, as it really kill my time.

Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry. New files will be created when required.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar to do a compatibility check.

Battery not availble BUT still running off battery!?!

So yesterday, my MacBook decided to not show up... what? Randomly, out of the blue! It had previously been working just fine, about 80% health, and then, all of a sudden, it stops recognizing that there's a battery installed. Here's the funny part, though... The battery still has a charge (as shown by LEDs on the bottom), and the MacBook still runs off the battery, despite it saying it doesn't have one! Unsurprisingly, the battery doesn't charge either.
The computer will only start up if plugged in, but can subsequently be unplugged to run on the remaining battery power.
It seems the problem here isn't the capacity of the battery, but the communication between the battery and the computer.
I've tried resetting the SMC and cleaning the contacts of the battery, but neither of those had any effects.
Do I have any recourse besides trying/buying a new battery?

I have the same exact problem...totally out of the blue. You definitely don't need a new battery because my problem started couple of days after I purchased a brand new battery.
I think it might be the battery connector to the logic board. In almost all other cases with this problem, when the battery isn't recognized by the mac, then you have two of the following: it doesn't charge AND the computer doesn't run off the battery alone, even if the battery indicates that it still has juice left.
Unless instructed otherwise, I'm going to open up the computer and re-connect and clean the battery connector.
Also, do you have the updated battery software?

Trying to link large file to email. keep getting asked for master pw to security device. I have changed master pw on firefox and TB but still same response.

I have tried over and over to send this large file. I've never synced before so i got that all set up. Then asking for master passwork to security device. Don't think I had ever set up an account so did that and created password. When trying to send the email I ask to link it goes to 'box' and I authorize thunderbird to use use it. then it ask for master password and I type that in and it doesn't work. I have reset master pw for firefox and thunderbird and still can't get it to work. I really don't know what I am doing here so any help is greatly appreciated. Thanks!

In my previous response, I gave a link to this website page:
http://kb.mozillazine.org/Master_password
It contained some information about what to do if TB keeps asking for a 'Master Password' which was never set. This was an old bug that was resolved years ago, so it is surprising you are getting it assuming the Thunderbird Master Password was never set.
However, your comments are confusing because they are conflicting; in your question you say:
'' I have changed master pw on firefox and TB ''
This implies you set a master password in Thunderbird and changed it, but in last comment you say you never defined it:
'' I have used the Firefox direction to eliminate the master password, which I never defined in the first place,''
I'm not sure what you mean by 'I have used the Firefox direction' - perhaps you mean the link I gave. As of course we are not talking about firefox :)
So, at this point, it is hard to know what you did because you are posting conflicting information.
Using info at the link, I presume you tried this:
quote
''Thunderbird: Choose Tools -> Error Console, paste the expression: openDialog("chrome://pippki/content/resetpassword.xul") and press the Evaluate button. That will open a dialog asking you if you want to reset your password. ''
quote
''If that doesn't work exit Thunderbird and delete the '''key3.db''' file in your profile.''
Did you do this? You do not say if you did this.
At no point does it say uninstall Mozilla Thunderbird program, so I do not know why you would do it. Uninstalling the Program has nothing to do with your Profile for very obvious reasons.
'''More clearer instructions on how to delete the '''key3.db''' file.'''
Make hidden files and folders visible:
* http://kb.mozillazine.org/Show_hidden_files_and_folders
The AppData folder is folder is a hidden folder; to show hidden folders, open a Windows Explorer window and choose "Organize → Folder and Search Options → Folder Options → View (tab) → Show hidden files and folders".
Assuming your Profile was stored in the default place, it can be located here:
* C:\Users\Windows user name\AppData\Roaming\Thunderbird\Profiles\Profile name\
Thunderbird must be closed before doing anything in the Profile folders.
If you have since reinstalled Thunderbird, you can also use it to get quick access to your Profile folders.
In Thunderbird

* click on 'show folder' button
* '''Close/Exit Thunderbird - this is important'''
* Look for and delete this file : '''key3.db''' file.

Services of 2nd instance disappearded from SQL Server 2012 Configuration Manager but still running

We recently configured multiple SQL Server 2012 R1 (two-node) clusters. Some with two instances. However, we discovered later that the Configuration Manager only lists the services of the 1st instance (the default MSSQLSERVER instance). The other named instance
is still running and can be failed over from one node to the other using Cluster Failover Manager but the services are not showing up in Configuration Manager in any of the two nodes.
Any thoughts as to why we see this odd behavior and how to fix it? We have done two instances before in SQL Server 2008 R2 but never saw this behavior.
Thanks,
Omer

Please see my answer above about the SQLCM version. We use the highest.
As I said before that this happens only when we have two instances running in a SQL2012 cluster. We configured 7 SQL 2012 clusters. three of them have two instances but only the services of one instance are displayed in CM. Services of the default instance
are listed in two of these clusters while services of the named instance are listed in the 3rd one.
One thing to note about these configurations is that the installer could not bring the services at the end of installation online because it did not have permission to create the computer objects in AD during setup thus we had to follow a known workaround
that involves having the domain admin fix these permissions and then we were able to add the SQL Agent Service to the cluster and bring the services online after modifying the ConfigurationState key value of each instance in the registry.
The installer account is setup as a local admin and we asked the domain admin to give it "Read All properties" and "create computer objects" in AD but for some reason it does not seem to have the ability to create these computer objects during installation
and the objects are to be pre-created and their permissions reset afterward.
I am giving this information and I am not sure if it has anything to do with the fact that SQLCM is listing the services of one instance and not the other.

Battery indicator @ 0%, but still runs

I've had my macbook for about 2-3 years now. I have noticed the battery performance getting worse with time, but lately it has gone way down! after fully charging, the batter will show only about 20-30minutes of time, within about 3 minutes will drop to 90 percent and continue to degrade rapidly. So yesterday I decided to just let the battery die before plugging it in. Once the indicator read 0%, it continued to run (not plugged in) for about 1 hour while playing music and internet surfing and could've gone longer, but I had to leave the house. So I powered it down, and didn't plug it in. When I got back, it was completely dead, and wouldn't turn on without the adapter plugged in. So I plugged in, turned it on, and it still was reading 0% and it started charging. When I unplugged it, it went into sleep mode and wouldn't wake up until plugged back in. Even after it had been charging for 20 minutes, it still wouldn't run without the adapter.
Sorry for being so lengthy, but I hope someone out there can help!

Perhaps the SPID is in rollback status. You can check the rollback progress with:

IPhone 4s keyboard shortcuts disappeared but still work ?

I use both french and English keyboards as I switch a lot. I've disabled auto-correction but not Spell check. I've created many useful keyboard shortcuts which now have disappeared from the shortcut list in the keyboard menu but they all still work when I type them in. I can add a new shortcut which then also works but the shortcut list still remains empty. Not the end of the world but still a weird glitch.

Here is my post from another thread:
The same thing happened to me and the Genius bar did a reset yesterday. The problem appear fixed... Until today. Back to the Genius bar this afternoon. I'm not going to let them do another reset this time if that's the only thing they have to offer.
Trial 2:
The Apple store tried all different things without success, so they gave me a new iPhone. They restored everything back via iCloud onto the new phone. Checked the shortcuts--the problem still exists! Blank.
Now I'm supposed to go back for a full hour appt so they can manually install everything onto my phone from my saved laptop. I may not do that and just live without the shortcuts until an update is available.
They said they've never encountered this problem before, but will submit it as a case to Apple.
My suggestion is that everyone having this issue to report it to a Genius Bar and make sure they submit it to Apple. Hopefully then Apple will fix this glitch on the next software update.

Schedule Tasks removed but still running

Morning all,
We are a college of 90+ Mac's but primally PC, we are using Apple Remote Desktop 3.4 (I'm aware that 3.5.1 is available) so I'm self training but have an issue as of yet I have been unable to resolve.
Like a few of you here I have set Schedule task in ARD then removed them but the tasks are still running each night, I have seen a few posts but no solution,
There is a discussion indicating that the tasks are stored in the 'com.apple.remotedesktop.plist' but I cannot confirm that as the file is not in readable text.
I did find a Tasks Server folder '/Library/Application Support/Apple/Remote Desktop/Tasks Server/' but I'm unable to get to is from finder or the terminal as the permissions are stopping my access.
The tasks being set or a shutdown this was set to happen @ 7:30 PM but the college require the stations to shutdown later @ 10:00 pm and the stations are now shutting down in the middle of a class.
Can any one help
Thanks Simon

Hi,
Yap I turned off all the energy saver options that have been set in workgroup manager also I'm still getting history of the shutdowns done by ARD, but not able to turn off the ARD computer as it is the X Server.
I did find the file "~/Library/Preferences/com.apple.RemoteDesktop" but I was unable to read it but I'll give the command above a go.
Thanks For your help
Simon

I corrupted the firefox profile file using profile manager and firefox thinks it is still running and asks me to close but there is no instance of it running...I have tried several re-installs but cannot resolve the problem....

.........I have deleted the .ini file associated with the profile file and the profile file itself...have tried to locate the "lock" file but cannot find the file in the specified path on the support forum for this problem....I believe there is a file mounted in another directory somewhere that firefox is seeing....I would really like to be able to use firefox as the default browser on this new linux (ubuntu) install...it was working prior to my trying to import my profile from the windows partition.....

See this.

Desktop shortcuts and folders disappearing but still virtually available on SSD

Hi,
I've had a bit of an issue today where I loaded up my PC (Windows 7) and half my desktop has disappeared, At the moment as I run dual monitors, when I first attached my second monitor many months ago some of my desktop icons were chucked to the right and
some to the left but with this case they have disappeared.
When I shut down my PC last night everything was okay and nothing was missing (I did install a few game updates last night but that is the norm for me) Today, the shortcuts that are missing are still available on my SSD (:D) drive which is set as first boot
order. I can search to the desktop folder on the SSD and all shortcuts are intact. The desktop currently running is from my standard hard drive (:C) which was more of a backup and for space. On the "My Computer" screen i'm 100% sure my SSD was first
in the list (left in list) but it appears now to have switched with my regular hard drive
Can anyone tell me a way to reverse this? i've tried system restore but as it assumes my last restore point was the windows updates that installed today (As the only restore points it looks for is the hard drive and not SSD)
I would really appreciate any help.
Thanks

Hello Jason2710,
This can happen if the the System Maintenance troubleshooter detects the shortcuts as broken.
