A copy of Firefox is already open. Only one copy of Firefox can be open at a time -- HOW DO I SOLVE THIS?

I have read the other threads and tried what they suggested and am still unable to solve this.
I am using OSX 10.7.5
I have tried uninstalling and reinstalling firefox. This did not work.
Any suggestions?

Create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":
*https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer some files from your old profile (if there is one) to that new profile, but be careful not to copy corrupted files.

    Turn off Time Machine before you open iMovie. It's a semi-known issue right now.

  • Only one computer/device connected to wireless interenet at a time, how can I change this?

    I had this set up a couple years ago to where only one computer could be connected to my wireless internet. However, now that I have 2 laptops, an xbox and a Wii, I would like to change this to where more than one computer or device can be connected to my internet at a time. Anyone got a clue how to change this?
    I have a WRT54G wireless router.
    Thanks.

    Have you tried to connect the devices? If so, is the router allowing you to? If not, are you getting any error messages?
    By default, if you setup the router before, anyone should be able to connect to it without a problem.

  • Firefox gives error by opening Yahoo Mail. Other webbrowers don't have this problem. How do I solve this

    Firefox gives an error by opening Yahoo mailbox.
    It mentions every time: 404 Not Found
    When using other webbrowers Yahoo is doing fine.
    How do I solve this problem?

    Hello,
    '''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that turns off some settings and disables most add-ons (extensions and themes).
    ''(If you're using an added theme, switch to the Default theme.)''
    If Firefox is open, you can restart in Firefox Safe Mode from the Help menu by clicking on the '''Restart with Add-ons Disabled...''' menu item:<br>
    [[Image:FirefoxSafeMode|width=520]]<br><br>
    If Firefox is not running, you can start Firefox in Safe Mode as follows:
    * On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * On Mac: Hold the '''option''' key while starting Firefox.
    * On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
    ''Once you get the pop-up, just select "'Start in Safe Mode"''
    [[Image:Safe Mode Fx 15 - Win]]
    '''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
    ''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
    When you figure out what's causing your issues, please let us know. It might help others with the same problem.
    Thank you.

  • Whewn i try to download firefox 4.0, it opens mozilla setup, wwhich prevents downloading as mozilla should be closed, how do i solve this

    Firefox says to close Mozilla, which I do, but during the course of downloading Firefox 4.0 it re-opens mozilla, which prevents me from downloading 4.0. How do I solve this?

    I have attached jpeg files of both Firefox upgrade options (5 files) -
    Firefox 18.0.1 US English (with messaging that MailCheck is not
    supported; 2 files)
    Firefox 18.0 German (showing the download and installation of Firefox
    18.0 that supports MailCheck, but in German; 3 files)
    I hope these are helpful in addressing the problems I've been experiencing.

    Hi, I would like every new tab I open to open my homepage. How do I set this? I'm on a PC and downloaded the latest version of Firefox today. Many thanks!

    Have a look at the [https://addons.mozilla.org/firefox/addon/new-tab-homepage/?src=ss New Tab Homepage] or the [https://addons.mozilla.org/en-US/firefox/addon/my-homepage/?src=search My Homepage] extensions. With My Homepage, if your homepage is set to a search engine, it will give focus to the homepage search bar instead of the address bar when opening a new tab.

  • I turned off my computer while installing something and now I only get the start-up screen with the apple logo. How do I fix this?

    Reinstall OS X:
    Reinstall OS X without erasing the drive
    Do the following:
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

(SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button.

Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Continue button.
    Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

  • I cannot view pdf files on Safari, instead they download and open in viewer. How do I change this?

    Does anyone have a solution for this???
    "I cannot view pdf files on Safari, instead they download and open in viewer. How do I change this?"

    Back up all data. Please read this whole message before doing anything, so you'll know what to expect.
    Open Safari's preferences dialog and make notes of everything you would need to recreate the basic settings, such as your home page. That includes the settings of Safari extensions, if any are installed.
    Triple-click the line below to select it, then copy the selected text to the Clipboard (command-C):
    ~/Library/Preferences/com.apple.Safari.plist
    Quit Safari. In the Finder, select
    Go ▹ Go to Folder
    from the menu bar. Paste (command-V) into the box that opens and press return. A Finder window will open with a file selected. Move the selected file to the Desktop, leaving the window open.
    Launch Safari. Its settings will have reverted to what they were they first time you launched it. Your bookmarks, history, and AutoFill data will be preserved.
    Test. If Safari now works as expected, recreate its settings and delete the file you moved to the Desktop. Otherwise, quit Safari again and put the file you moved back where it was, overwriting the newer one created in its place. Post your results.

  • When I i open a picture from my Documents it automatically opens in Photoshop.  I want it to open in Lightroom. How do I change this preference?

    When I i open a picture from my Documents it automatically opens in Photoshop.  I want it to open in Lightroom. How do I change this preference?

    You cannot open an image with LR as you would with Photoshop , or Elements. (or a word document, etc)
    The Lightroom program can only open "Catalog" files  (*.LRCAT)   Opening a .LRCAT file will automatically open Lightroom.
    To edit images in LR you must first open the program, then IMPORT the image into the Catalog database (only ever once), then you select the preview thumbnail and go to the Develop module ( press "D")
    Your edits in the Develop module will show on the preview in the library grid.
    Your original image file is not altered, so will not look any different in File Explorer or Finder.
    To get an image file with your Develop edits applied, you must "Export" a derivative file in JPG or TIFF format.

    I have installed firefox 7 as my browser today and now those menus dont work any more how do I solve this problem?

    Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
    * Don't make any changes on the Safe mode start window.
    See:
    * [[Troubleshooting extensions and themes]]
    * [[Troubleshooting plugins]]
    If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    * Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
    * Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
