  • At times when we try to open Firefox we get a message it is already running and have to restart comp . Why is this ?It happens with all users . Thank you

    We have gone on our comp after a while and tried to open Firefox . When we do we get a message "Firefox is running close app or restart comp . " Now the thing is I was on it earlier and closed it with the close button . Then say checked mail , or looked at pictures on my comp . Then I would want to use the browser again and when I tried to access it I get that message . Rest assured it had been closed . This issue did not happen until I downloaded Firefox4 . We did not have this problem with the earlier versions of Firefox .

  • I often get an error message when I try to open Firefox 8.0.1 that it's already running...it isn't...and the only way I can open it is to restart my computer. Is there a way to fix that problem or to download an older version that doesn't do that?

    I tried downloaded the browser again from IE, but that hasn't helped the problem.

    [[Firefox is already running but is not responding]] has steps that you can try. It sounds like you may have something that is hanging your browser on exit (probably an extension or a locked profile) and the steps on that page should help clear it up.

    Did it not show up in yoour Software Update (in System Preferences)?
    You can directly download 10.5.2 from Apple from here.  And if that doesn't work (it didn't when I just tried it -- something wrong with the apple itunes site I assume) download it through macupdate from here.

    I have  a iphone 5 and i can not figure out how to turn on the LED notification light. is this even possable? if not how do i know if i missed a call when i was not there to answer it visualy

    If you were not there, how would you see the led?
    Anyway missed calls will appear on your Lock screen under the Missed tab.
    Or a small red numbered badge will appear on the Phone App icon when you have missed calls. You can then access the Recents Tab in the Phone App to see whcih calls were missed.
    Missed Calls are shown in red there

  • When I try to open Firefox, MSN pops up even after I specified Firefox as my default browser. HELP!

    I downloaded a VIAO update, now can't open Firefox. When I try to open Firefox, MSN opens in HTML. I access my mail from I.E. I've also had problems with my facebook page. Ran virus scan and Malwarebytes. All my bookmarks and favorites are on Firefox.

    Check that you do not run Firefox as Administrator.
    Right-click the Firefox desktop shortcut and choose "Properties".
    In the Compatibility tab, make sure that Privilege Level: "Run this program as Administrator" is not selected.
    You also need to check the Properties of the firefox.exe program in the Firefox program directory.
    If you can't make the changes then you need to start Windows Explorer as Administrator.

  • HT5624 how do I change the security questions on my daughters itunes account. I do not remember adding the questions and they do not make sence to me. can not figure out how to get to her  email account that it is showing for her altern

    I cant seem to be able to change the secutity questions on my minor daughters itunes account. I set the account up but I do not remember adding the security questions and they do not make sense to me. It says that the alternate account it would be sent to is@ me.com but I can not figure our how to get to it to retreive the email to reset the questions. My daughters account may have recently been hacked so I am trying to change all passwords. I changed the itunes account and added another email but I still can not change security questions in case I ever need them.
    <Email Edited by Host>

    We are fellow users here on these user-to-user forums, you're not talking to iTunes Support nor Apple - I've asked the hosts to remove your email address from your post (it's not a good idea to post personal info on any public forum).
    The reset link on an account will only show if there is a rescue email address on it, alternate email addresses are different and not used for resetting them. If she has a rescue email address on her account then steps 1 to 5 half-way down this page will give you a reset link on the account : http://support.apple.com/kb/HT5312
    Navigate to appleid.apple.com using your web browser.
    Click "Manage your account"
    When prompted, sign in using your Apple ID and password.
    Click Password & Security
    You'll be asked to answer 2 of your 3 security questions before you can make any modifications. If you are unable to remember your answers, you can choose to send an email to your rescue email to reset your security questions.
    If she doesn't have a rescue email address (you won't be able to add one until you can answer your questions) then you will need to contact Support in your country to get the questions reset.
    Contacting Apple about account security : http://support.apple.com/kb/HT5699
    When they've been reset (and if you don't already have a rescue email address) you can then use steps 1 to 7 half-way down the HT5312 link above to add a rescue email address for potential future use

    as I said on top. Installed firefox 4 on 5/17. It was working okay until today. When I try to get online I click on my mozilla icon as always. A window pops up and says firefox.exe. what program would u like to use to open It shows me mozilla and I click on it. Then says do u want to run file and save.Browser opens tabs com up with search bar but the page is white blank. I have to go to the search bar and enter what wbsite i want to go to . Then I can pretty much go anywhere. What should I do? should I uninstall everything? can I still get back a older version like 3.6? How can I go about this.

    Does if help if you check the security tab in the properties of the file and remove a possible internet protection?

  • When I try to open firefox it pops up, "do you want to allow changes to your hard drive" everytime

    Firefox update while I was trying to resolve a issue with a brother fax drive to update for windows 7, now every time I go to firefox it pops up, "Do you want to allow changes on your hard drive" as if it didn't finish, so I answer "yes", firefox browser comes up, but if I get out and go back in it does the same thing.
    in the pop up window is listed; C:\program file(x86)Mozilla firefox\firefox.exe
    But when I search it, nothing

    Check that you do not run Firefox as Administrator.
    Right-click the Firefox desktop shortcut and choose "Properties".
    In the Compatibility tab, make sure that Privilege Level: "Run this program as Administrator" is not selected.

  • When I open Firefox a pop-up box appears with no conent and I must close it to continue.

    When I first open Firefox a window appears over my home screen with two choices, neither of which does anything when I click on it. I can close the box and continue. Sometimes I can not close a program in Firefox because the same box pops up when I try to close the window.

    That is a problem with the ThinkVantage Password Manager Extension.

  • When I close Firefox then try to open it again, it informs me it is already running and continues to do so regardless of how many times I restart the computer.

    I bought a new computer. I installed Firefox 7.0 then updated to 8.0. When I was finished with Firefox, I closed it. Later when I attempted to open it I was greeted with the message Firefox is already running. It suggested I restart the computer. I did so and continued to receive the same message. Surely, shutting the computer off should close Firefox. I have to use Internet Explorer to contact you.

    Sounds like Firefox is "hanging at exit". That problem is frequently caused by an Extension or a Plugin. Read all of the following articles.<br /><br />

  • TS3212 i have windows 8.1 when i try to open i tunes store it says has occured a problem and must close program

    I have windows 8.1 and when I try to access the itunes store it gives me this message.
    A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is avialable. This all started after downloading 8.1

    I had the same problem.  This is the way to fix it.  Be sure to reboot after you copy that file into the iTunes folder indicated below:
    Copy QTMovieWin.dll from:  C:\Program Files (x86)\Common Files\Apple\Apple Application Support
    to: C:\Program Files (x86)\iTunes
    If you have a problem, let me know.  I can post screenshots if you need them.
