Did you try a new profile?
Create a new profile as a test to check if your current profile is causing the problems.<br />
See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]]
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

I cannot get Firefox to open, no matter what I do. Anyone know how to fix this?

After a power outage, I cannot open Firefox 3.6.10.
If anyone has any suggestions other than reinstalling the OS, please let me know.
Thanks!

I can't get more than one window of Firefox to open no matter what I try. Help!

I recently had a virus and had to do a system restore to about a month ago. After the restore everything worked okay, except for Firefox. Now I can't open more than one Firefox window at a time and the window that is open is having a bunch of problems (right clicking won't open things into tabs, the back button isn't working, etc.). I've tried uninstalling and reinstalling Firefox, but that did nothing.

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the ''Safe mode'' start window.
You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")

Cannot make my QT files open in QT7

For some reason I cannot make the default for opening my Pro Res QT files open in QT7. They always open with Soundtrack Pro , until I do, "Open with QT 7" then its ok. But checking "All Applications" and "Always use this" has no effect. Am I doing something wrong?

Right click on one of the files in the browser and select "Get Info"
Then under the 'open with' section, select the default application you want.

When I close Firefox another Firefox browser opens. WHY and how do I stop this?

Every time I close Firefox another Firefox browser opens. Then I close that one and it stays closed. How do I stop it from opening a new Firefox browser on it's own?

Is it possible that you actually have two Firefox windows open and Windows 7 is showing one Firefox on the System task bar, but if you were wave mouse over that, you might see two windows.
To Close Firefox use File > Exit (Alt+F > Exit)
and not the X in the upper right corner which only closes the Window and may or may not close Firefox if it is the last window. The reason it does not always close Firefox is that there may be other tasks running so you don't see Firefox anywhere but in the System Task Manager on the Processes Tab which is where you can see if firefox.exe is running or not. Shortcut to Task Manager on Windows 7 is Ctrl+Shift+Esc (for other Windows systems Ctrl+Alt+Del , select Task Manager,...)

Display "Application over 20MB" when I type OK button, the appearance will not go away and make me unable to open other applications, what to do and whether it must be restarted

display "Application over 20MB" when I type OK button, the appearance will not go away and make me unable to open other applications, what to do and whether it must be restarted?

The 20 meg message is the download limit for 3G. If you can't get rid of the 'OK' message then you can do a reset by pressing and holding both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
You should be able to download the apps by switching to wifi on your iPad or downloading them on your computer's iTunes and syncing them or dragging and dropping them over to the iPad device.

ITunes will not shut off. Since I upgraded the software, itunes opens no matter what program I am using and when I close it , it will just reopen over whatever I am using. this is very annoying!!!!

iTunes will not shut off. Since I upgraded my software, itunes opens no matter what program I am trying to use. If I close it it automatically opens moments later and interferes with what I am working on. This is so annoying

This is probably occuring because your Mac is attempting to wirelessly sync with a device. Try unchecking the checkbox that reads "Open iTunes when device is connected" (this option can be found under the general page of iTunes when you have a device connected).

I cannot make Win7 firefox home icon open Yahoo USA even though I have dragged it over.

I am using Win 7 and firefox keeps opening my home country's Yahoo site even though I did as told and dragged it to the HOME icon. What can I do to open some area to force Yahoo USA to be my home page? My previous XP computer was able to do this.

How does Yahoo detect location? You can turn on Do not track? [[Settings for privacy, browsing history and do-not-track]]

-running version 17.0 on Firefox

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.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

I have just updated my iTunes to 11.1.3. I followed all correct steps, restarted my computer etc. But iTunes will now not open no matter what I try and do. Please help me!!!!!!!!

I have just updated my iTunes to 11.1.3. I followed all correct steps, restarted my computer etc but now I cannot open iTunes not matter what I try and do.
Very frustrating. Have read the trouble shooting info on Apple website but nothing has worked.
Someone please help. I cannot access any of my music.

Open Finder. Go to the "Go" menu in the menu bar. Press and hold Control and click on Library. Go to "Preferences". Find a file named, "com.apple.iTunes.plist" and delete that file. This won't delete your iTunes content. It will reset iTunes. Try it again.

Cannot empty trash on my eMac no matter what I do.

It has 2 folders in it - an iMovie cache and media folder in it. I tried holding down the option key when emptying. I always "secure empty" all trash files. Please help because the trash is taking up a lot of HD space. The progress bar window pops up but sometimes there is no "blue" progress indicator and sometimes there is no blue indicator at all. I have allowed it to run for over an hour. There is approximately 787 MB in the media folder and only 112 kb in the cache folder.

If you have the problem where you can’t empty the Trash or eject a disk because something is preventing you? Usually the reason is because some application has a file open, and thus you can’t get rid of the disk or trash the file. Then use What’s Keeping Me! What’s Keeping Me will identify the application that is preventing you from accomplishing your task. You can then use What's Keeping Me to quit, relaunch, or kill the problem application so you can get on with your business.

Sometimes it happens that the Finder just doesn't want to empty the trash anymore and says "The operation cannot be completed because the item "" is in use.". That's a good warning if it is true, but sometimes you want to get rid of an application and this warning appears even though the only thing running is the Finder. Usually after a restart you can delete it. But that is very time consuming and even then, it is sometimes still stuck not wanting to be deleted. There is a risky command that can be used in the Terminal that will empty the trash no matter what. Risky because a simple error in the syntax could erase a lot of stuff that you want to keep.
There is a way of forcing the Finder to empty the trash no matter what! It is done in the freeware customization and maintenance application OnyX (download @ http://www.titanium.free.fr/pgs/english/apps.html ). Once you loaded OnyX and entered your administrator password, choose "Cleaning" in the top bar. Click on the "Trash" tab. You can now choose whether you want to "Delete" or to "Securely Delete" (by overwriting) and click Execute. That's it, it will force the Finder to empty the trash even if the files are in use!
Many times, depressing the Option key while emptying Trash will empty problem files. Another method – start by depressing the mouse over the Trash icon. Then empty trash from the pop-up menu. The files should be emptied.
Also look at these links.

Some attachments won't download and open, no matter what

Hello,
On my Q10 with the latest 10.2 software, some attachments don't download at all. I work a lot with images so this is a nuisance.
If I click them while viewing the message in the hub, the progress bar continues almost to the end and then it gets stuck, never moving again. Even weirder: in one email, one out of two attachments downloaded and opened fine, the other didn't. No matter what, the attachments that the Q10 refuses to download are unavailable for viewing on the device, but open perfectly fine on a PC. Forwarding those from the Q10 is impossible, such "sent" messages get stuck with a clock icon.
In all cases the attachments have been images, but I'm not sure if it has something to do.
This happens with multiple senders and multiple accounts configured as IMAP w/ Gmail.
Any solutions or hints how to debug would be appreciated.

I have not encountered this. I just sent myself a test message with an attachment to see I could see something, Nothing jumps out at me.
With that email with two attachments and one was fine and the other was a problem, was there any difference between the two that might be a clue? Or if the two attachments were essentially the same, that's a clue as well. (It could be random and have nothing to do with the file.)
Is Gmail the only service you have been using? I wonder if you would have the same trouble with another, such as Outlook or Yahoo or an ISP email account?

Firefox says it has an update but when I select update it says it cannot update because Firefox is open. It is not open anywhere else.

Those are pretty much the details. I have completely shut down and restarted. I have done a restore (which seemed to work for a while but then it went right back to doing what it had been doing).

Can you give the exact wording of the message that is telling you your laptop needs an update?
