Firefox shuts down of its own accord when I haven't touched the pc for some time, usually overnight.

As above. When I restart Firefox it always opens in the same position on the monitor and the same size window even though that wasn't the last position/size as when I left it.
This is not a crash, it just disappears.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.

Is it possible that you or someone who knows your iCloud sign on went into the Find My iPhone app and erased your device via iCloud? Because that is what that message is saying.
Have you tried to sign on with your Apple ID and password?
Was it online prior to this incident happening?

My PowerBook shuts down on its own (persists when RAM is changed)

Hi all,
My PowerBook shuts down on its own. It will display the "Are you sure you want to shut down your computer now?", and even with me clicking Cancel, it will just shut off immediately after displaying the sign, as if I pressed and held the Power Button.
I've sinced change the RAM back to the default piece, but the problem persists.
Moreover it's a random, although frequent and frustrating, occurance, so I'm not sure if the service centre will take it in since I cannot reproduce the problem.
I'm using it on a 1920x1200 display.

http://docs.info.apple.com/article.html?artnum=14449
first you can try resetting Power Manager.
the rpoblem may be caused by some software bug, try making new user, then log in as new user and work for a while - if it works ok it's something in the original user software.
then you can try "archive and install" of the OS.
also, problem maybe caused by bad keyboard, top case (where the power button is) or logic board.
anyways keep files backed up and maybe get it diagnosed by service shop.

Imac G5 shutting down of its own accord

now I know the first thing you will say is check your system settings but I have, have taken off all energy saving functions etc.
I switch on my machine and read emails etc, sometimes open Quark/Photoshop ready to start work, then go away for an hour (school run etc), when I come back it has shut down, I have not seen it doing it so can't say if it comes up with an error message but when I restart I get no error messages at all, and all works fine, have no other problems. It has only started doing it over the last week and I'm stuck as to what to do to fix the problem can anyone help?
Cheers

If, in Console, you see messages about maximum temperature exceeded for 30 seconds, you have a thermal problem, either a failing Power Supply Unit, dried thermal paste, bulging or leaking caps or a bad connection.
Plenty of choices, you can open your machine and look to see if any of the caps is leaking or swollen, you can also clean all the dust out of the machine and make sure the fans and air vents are clean.
Then reset your SMU:
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Press and hold the power button for 5 seconds.
4. Release the power button.
5. Attach the computers power cable.
6. Press the power button to turn on the computer.
After that, reset the PRAM and please post back and let us know how things went.
It would also help if you would list the exact model of G5 iMac you have.

Iphone likes to shut down on its own when handled

For the last week my iphone has got a mind of its own and like to try to shut down on its own. Sometimes it would give me the red button+slide to turn off...sometimes it just goes to the Apple logo then shuts down.
No hacks on it, maybe two apps max like ebay so really nothing that would point out to an issue. This is also a replacement my original phone had a screen issue this summer where you could not touch anything else than the bottom bar. I swapped it for this one so it is virtually new.
Not sure if it is the button on the top that is stuck and it does not look like it.
Any similar experiences? I heard other users had issues with their iphone shutting down for no reason.

It does sound like the Sleep/Wake button may be stuck or overly sensitive.
If you lightly tap on it, does the phone turn off?

My iPad 3/new shuts down on its own.

My iPad 3/new shuts down on its own. Not off completely though. The screen goes black and I have to hit the center button, prompting the lock screen to appear. I have rebooted it completely, and not long ago I restored it. What do I do? I'm afraid if I take it to a store they won't be able to help me because I can always recreate the problem. It's random.

I would love to agree with that, but it happens when Im actually using it. I would love to say its the app I was in too, but it has happened while in different apps. Nook app, Simpsons Tapped Out app, Clumsy Ninja, Safari. I will be scrolling or touching the screen for whatever reason and off it goes.

My S5 shuts down on its own with no warning, no rhyme or reason. It attempts to factory reboot when it does it too! It freezes up at least once a week and becomes a $600 worthless brick. This has all been happening since day two that I got it. Went back to Verizon store and they told me nothing was wrong with my phone and they would not replace it. I'm at my wit's end. HELP!

BambieS5,
Sorry to hear about your trouble with the s5! Does the trouble that you are having persist in Safe Mode? http://vz.to/1xp1XUi . Does the battery have any signs of cracking, corrosion or swelling?

Macbook Pro 2010 upgraded from Mavericks to Yosemite keeps shutting down on its own

I upgraded to OS X Yosemite about a month ago, I have a macbook pro 2010, and in the last two weeks it started shutting down on its own. At first when i'd wake it, the fan would come on loudly and then it would shut down. In the last couple of days, I would make sure all programs were shut when it wasn't in use and then put it to sleep but every time i'd return it would be shut down and need a hard restart. If i just pressed the on button lightly it wouldn't start. And when i turn it on the fan comes on immediately. I'm a publisher so I'm working in indesign and illustrator a lot but I keep a constant look out for my memory and this isn't the problem. I'm working to a deadline here and can't afford to lose my computer for 3 days in the mac store (I live in Barbados) to get it fixed. Any advise?
Thanks

Is the little LED on your adapter's MagSafe plug glowing when it's connected? What color?
It sounds as though your battery is drained and the adapter isn't charging it. Try resetting the SMC:

That may start the battery charging again.

5310b shuts down on its own

How come my Nokia 5310b shuts down on its own? It's a new phone and the battery is charged.

The only indicator I get when my phone will be shut down is a sign I get next to the batter sign. The sign looks like a yellow envelope and it rotates.
When I don't get that sign, the phone works fine.
Also, usually when I see that sign, the phone does not lock itself up, otherwise it locks up, which is normal.

Beer might have gone into MacBook Pro from the back, shut down on its own 5 minutes later. what to do?

I'm currently working in Myanmar and no chance to going into a Mac service provider or store. I was using my Macbook Pro (mid 2010) when beer was spilled onto the table. I lifted the computer instantly and as i did not see liquid on the machine and also it had a protective cover i was sure no liquid got in. I removed the cover and it was dry but then 5 minutes later it shut down on its own and it would not turn back on or charge. I left it for an hour or so and then it turned back on and was charging but then since i thought that may be it was because some liquid got in, I turned it off again immediately and disconnected from power source.
what is the best way to proceed knowing i won't be able to bring it in to a technician anytime soon?

without on hand diagnostics, nobody can tell you the correct answer on that. No.
5 minutes later it shut down on its own and it would not turn back on or charge.
bad news
Liquid spills, why your MacBook chassis is a one-way valve for spills
After a substantial spill many people will turn their notebook upside down and shake it, not only does this not work, but it spreads liquid havoc throughout your machine and makes things often as bad as possible.
The keyboard itself acts like a one way valve in the case of a substantial liquid spill. While liquid pours into the bottom chassis easy, it does not come out easily at all, and in the case of any spill, most of it will not come out by turning it upside down. Disconnect all power and contact Apple for diagnostics and repair.
Do not attempt to, after a spill, ‘dry out your MacBook’ and test it
After a spill most people invariably try to “dry out” their notebook by various methods, including hair dryers and otherwise. This both does not work, and after a substantial spill of any magnitude, even if the liquid was water, residue is left behind.
There are additionally many very tight places inside your notebook where liquids will linger for a very long time, and cause corrosion or worse.
Immediately unplug your notebook and contact Apple for in shop diagnostics and parts replacement.
In the case of very minor spills people will “dry out” their notebook and feel success that their notebook is working ok, however invariably in nearly all instances after 4-14 days an error / fault pops up and is usually followed by more.
In case of a spill, damage estimates are impossible,.....anything can be fixed, without question.......the question is cost.
contact Apple for in shop diagnostics and cost estimation ....possible parts replacement.

My iPad air keeps shutting down on its own!

My iPad air keeps shutting down on its own, and this is the second IPad Air doing this. I really don't want to go trade it in for another. Does anyone have the same issue and is there a way to fix it? And yes I've done the manual reset and computer reset.

Memory Size & The Impact of 64-bit Applications
The iPad Air, like the iPhone 5s, ships with 1GB of LPDDR3 memory. Apple frowns upon dissection of review samples but I think it’s a safe bet that we’re not talking about a PoP (Package-on-Package) configuration but rather discrete, external DRAM here. It’s also probably a safe bet that even the iPad mini with Retina Display will ship with 1GB of memory as well.
Something I didn’t have time to address in my iPhone 5s review was the impact of 64-bit applications on memory usage. I actually ran some tests after the 5s review hit but never got the chance to share the data, so I figured now is as good a time as any to do just that.
Unlike traditional desktop OSes, iOS doesn’t support paging to disk (or in this case, NAND). Application data can either reside in memory or the associated process is terminated and has to be reloaded the next time you request it. It’s a decision likely made to both maintain user experience and limit the number of program/erase cycles on the internal NAND.
The good news is that iOS was architected to run on as little hardware as possible and as a result tends to be quite memory efficient. There are also power implications of going to larger memories. The combination of these two things has kept Apple on the conservative side of increasing memory capacity on many iDevices.
The move to a 64-bit platform however does complicate things a bit. Moving to a larger memory address space increases the size of pointers, which in turn can increase the footprint of 64-bit applications compared to their 32-bit counterparts. So although there’s clearly a performance uplift from app developers recompiling in 64-bit mode (more registers, access to new instructions), there’s also an associated memory footprint penalty. Since the iPad Air and iPhone 5s don’t feature a corresponding increase in memory capacity, I wondered if this might be a problem going forward.
To find out I monitored total platform memory usage in a couple of scenarios. Before measuring I always manually quit all open apps and performed a hard reset on the device. Note that the data below is reporting both clean and dirty memory, so it’s possible that some of the memory space could be recovered in the event that another process needed it. I hoped to minimize the impact by always working on a cleanly reset platform and only testing one app at a time.
I looked at memory usage under the following scenarios:
1) A clean boot with no additional apps open
2) Running Mobile Safari with 4 tabs open (two AnandTech.com tabs, two Apple.com tabs, all showing the same content)
3) Infinity Blade 3 (64-bit enabled) sitting at the very first scene once you start the game
4) iOS Maps in hybrid view with 3D mode enabled, with a WiFi assisted GPS lock on my physical location
5) Google Maps in the same view, under the same conditions. I threw in this one to have a 32-bit app reference point.
In general you’re looking at a 20 - 30% increase in memory footprint when dealing with an all 64-bit environment. At worst, the device’s total memory usage never exceeded 60% of what ships with the platform but these are admittedly fairly light use cases. With more apps open, including some doing work in the background, I do see relatively aggressive eviction of apps from memory. The most visible case is when Safari tabs have to be reloaded upon switching to them. Applications being evicted from memory don’t tend to be a huge problem since the A7 can reload them quickly.
The tricky part is you don’t really need all that much more memory. Unfortunately as with any dual-channel memory architecture, you’re fairly limited in how you can increase memory capacity and still get peak performance. Apple’s only move here would be to go to 2GB, which understandably comes with both power and financial costs. The former is a bigger concern for the iPhone 5s, but on the iPad Air I would’ve expected a transition sooner rather than later.

HP officejet pro 8600 Plus shuts down on its own while making numerous copies.

My printer HP officejet Pro 8600 Plus keeps shutting down if I print or make more than 5 copies then gives me a message to avoid damage shut down the printer with the on button. Well it shuts down on its own.

Hello mb_bernhardt,
Welcome to the HP Support forums. I understand that your Officejet Pro 8600 Plus printer is giving you a Printer Failure message and then the printer shuts down.
I’ve included the A 'Printer Failure' Message That Might Include an '0x610000f6' or '0x61xxxxxx' Error Code Displays o... document. If the error message that you’ve received includes an Error code there is one set of instructions to follow, and if there is no Error code there is another set of instructions to follow.
