Firefox "loads" but fails to display.

After updating Firefox, the browser loads (it shows up as running in Task Manager) but fails to display on screen. In other words, it is completely unusable. I've uninstalled & reinstalled the program, without favorable results.

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to internet for Firefox and the plugin-container process and the updater process.

  • Firefox starts, but fails to display websites with no error message.

    Firefox starts, but when it tries to connect to a real website, i.e. google.com, mozilla.com, etc. it just... doesn't. There is no error message. There is no progress bar. No "Loading...". Nothing. It just continues to say "Untitled" in the tab name.
    I tried updating to the latest firefox version. I tried reinstalling firefox. I tried creating a new profile. I tried clearing cache/cookies/etc. Nothing I did caused any change.
    I have noticed that if I attempt to type in a random string of characters (clearly not a real website) or a made-up ip address, then it displays the proper error message... intermittently. I just tested it again, and apparently it doesn't always work.
    *sigh* What now?
    == This happened ==
    Every time Firefox opened
    == I went back to firefox after using Chrome.

    I have mac. And I have the same problem.
    First page loads - and I can click on any link from that to continue opening it in tabs. But when I open new tab cmd+t and enter a website address to location bar, nothing happens.
    I don't have a firewall.
    I already deleted Firefox from applications and reinstalled.

  • Firefox loads but does not display

    1. When I double click the Firefox icon on my desktop the firefox.exe application loads (per the Task Manager) but it does not display. I have to use Task Manager to end the process. FF will usually display on the second try, but I often get a "this is embarrassing" message. This has been going on fore several months.
    2. I don't know if this is related to the loading problem, but I frequently have to shut down & restart FF because some Bookmarks don't work when I click on them. Usually my Home Page icon at the top will work, but those in the Bookmark sidebar don't.

    I am surprised that 17 other people have this problem and no one has any ideas.
    Basically, I have had to abandon the use of Firefox and use IE ... is this a Microsoft conspiracy? I really like Firefox ... I am devastated.

  • Page loads but will not display

    I have an IP address that allows me to view my cctv cameras.It works fine with Internet Explorer,but when i enter the same address in to my safari browser the page seems to load but will not display anything.
    I assume its some thing do with my internet security settings but do not now where to find them to allow this site. Can any one help please.
    Thanks

    Try temporarily turning off your firewall via SystemPreferences>Security>Firewall. If the site then works you can turn the firewall back on and specifically allow Safari.

  • Safari loads but no window displayed,

    Safari seems to load but no window displayed. New Window doesn't help. Loading from Application folder, no difference. Yesterday I loaded an application DataGuardian, thought that might be confilicting so I removed it, no difference. Have rebooted several times. Looked for changes to system by date, no clue. Need a solution that doesn't require a web browser. I'm sending this from a different machine. THanks.

    Welcome to Apple Discussions
    You may have a corrupted preference file. Move to your Desktop from your User Library/Preferences folder .com.apple.safari.plist and restart Safari. Any change? If you now get a browser window, then reset the Preferences to your custom settings. If not, move the above file back to its original location replacing the newly created file.
    If no change, does the same problem occur if you open Safari from another User Account (create one if necessary in System Preferences>Accounts).

  • FF loads but does not display

    Since the upgrade to FF3.6, I've had several annoying glitches.
    1 Dclick desktop icon, FF loads into memory, but does not display. End task. Then Dclick the icon again. This time FF loads and displays normally.
    2. After closing FF with Save & Quit, next time I open FF, error message : "Well this is embarrassing, can't recover tabs". Start new session. FF opens with last tab instead of default site.
    3. On some sites I click icons and nothing happens. Sometimes other icons on same page will open, but most won't. Internet Explorer will open the same icons, so the Problem seems to be in FF.
    Am I the only one with these nuisances? Any help will be appreciated.

    Hello John.
    You may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
    Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
    If you want support for one of your add-ons, you'll need to contact its author.

  • PS opens files but fails to display them

    hi there! ive already done some searching but did not find anyone else having my problem.
    im using vista x64 and PS CS4 (updated). the problem occurs on both 32bit and 64bit versions.
    when i open an image with PS (does not matter which type or which way to open it), PS seems to open the file correctly, but does not display it at all.
    everything looks like the image is opened (f.e. small thumb of it in the layers window and the name of it in the title bar), but where the image should be displayed in fullsize you only see the grey PS background.
    it seems that besides this PS works completely fine. f.e. when i use the paint bucket tool on the grey area in the middle, the layer thumb changes to the color used..
    another strange thing: when i switch to another program and switch back to PS the grey background is gone and instead you see whatever program is beneath PS at that moment.. you can move the PS window and see right trough it, only the PS control windows are still displayed. thats what you see in the attached image: there is no screenshot of my explorer loaded in PS, it should be a picture of keira knightley.
    so far i have already tried to delete the PS settings and reinstall PS but it wont help.
    any help would be very appreciated!
    thanks in advance!

    Try resetting your preferences as described in the FAQ.

    You either have to physically delete (or rename) the preference files or, if using the Alt, Ctrl, and Shift method, be sure that you get a confirmation dialog.
    This resets all settings in Photoshop to factory defaults.
    A complete uninstall/re-install will not affect the preferences and a corrupt file there may be causing the problem.

  • Outlook 2010 loads but does not display on monitor

    Very strange problem. When I click on Outlook 2010, the splash screen appears and it seems to load, but does not appear on my monitor. Task Managerr shows the application is running, so I guess it is there somewhere. All the other Office 2010 programs work
    fine. 
    I am running Win 7 Professional 32bit, dual core 2.7 cpu, 4 gb ram. Everything else works fine. I was having a problem with Outlook 2003 crashing and had not tried Outlook 2010.
    Have the same problem in Safe mode.
    I did run scanpst.exe and it only found (and repaired) a few files that it felt were not important. I transferred my .pst file to my wife's computer and her copy of Outlook 2010 opened it fine. I used her computer to delete all items in the
    "deleted" file. My total pst file is about 142mb. I have defragmented this hard disk. I don't have a Win7 installation disk because I downloaded the Office 2010 file and used a legitimate key to activate it
    I think there is a simple answer. Appreciate your help in finding it.

    I found my problem. 
    “Add-ons” were the source of the problem.
    I believe there was a conflict between two programs: 
    Norton’s Security Suite and AnVir Security Suite.
    Both were trying to scan my incoming e-mail. 
    I uninstalled AnVir, reset Outlook back to its original configuration (i.e. reversed all the changes I described above), and my problem is gone.
    Not sure why this problem took so long to appear as both programs had been install for at least a month without issues. 
    I used AnVir and ZoneAlarm for over a year together without issues. 
    However, about one month ago, I uninstalled ZoneAlarm and installed Norton’s Security Suite.
    In any event, uninstalling AnVir solved the problem. 
    Uninstalling Norton’s and keeping AnVir would probably work as well.

  • Firefox screen saver starts to load, but fails and will not close. To get my computer back I have to do a "control/alt/delete. Why?

    I do not know which version I am using - I am truly computer illiterate. You will need to tell me what information you need, and how to find it. Sorry.
    At about the same time as this developed, I lost the ability to continually see the tool bars at the top and bottom of the screen- as if the page was too big for my screen. Don't know if they are connected problems.

    Try ( alt + cmd + esc ).  Gives you a menu of running applications, and a chance to "Force Quit".

  • Browser loads but doesn't display page

    When I click on a link my browser opens and seems to load (the percentage done increases). It is slow, but even when it reaches 100% it just stops, and nothing is displayed on the screen.
    My son's pal has fiddled with settings and fixed this, but I would like to know how to do this myself.
    Also, any idea what causes this? It seems that something I load messes up my settings.

    Could you try disabling graphics hardware acceleration? Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
    You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
    Then perform these steps:
    *Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
    *In the Firefox options window click the ''Advanced'' tab, then select "General".
    *In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
    *Now, restart Firefox and see if the problems persist.
    Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
    [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
    [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
