Firefox will not open full screen

Firefox will not maximize. I can mouse over it on the task bar and see it opened. But it will not display full screen or even part of the screen.

You use an out-of-date Firefox version. Update Firefox to 3.6.13. You'll have more details in [[Updating Firefox]].

  • ITunes will not open full screen mode in Mavericks

    Hello,
    Ever since a recent upgrade to Mavericks, iTunes will not open in full screen. When I click the full screen expander in the controls or in View>Enter Full Screen iTunes flashes the library and then back to the movie playing and makes the "funk" sound.
    Any thoughts?
    Thanks!

    Welcome to Apple Support Communities
    First, open System Preferences > General, and make sure that "Close windows when quitting an application" is marked. Then, open iTunes and press the Esc key to get out of full-screen, and close iTunes. The next time it starts, it should be in a classic window

  • Firefox will not use full screen for display

    I asked this a while back and never got it resolved. I hope someone can help because I've been using Firefox for years but for the past couple months have had to use other browsers because FF is not working properly.
    First of all- the display of any sites only takes up the middle os the screen. Even if I hit CTRL and scroll it enlarges the text but never expands to fill the whole screen as other browsers do. On my old computer I never had this problem but ever since I switched to my new one, with new flat panel monitor and Win7, I have been having this problem.
    Also, I chose the Win7 theme of high-contrast black with pink. This has resulted in issues with many sites not displaying their chosen backgrounds and worse yet even sometimes buttons and other content on the pages is obliterated/hidden/invisible. Like you can still click on something if you can find it. The old version of Flock which is FF based also has this problem (as well as having all-white url and toolbar areas so you cannot read anything) while Google Chrome and new Flock do not- so it is definitely a problem with the coding here.
    Please help, I would like to use Firefox again if I could also enjoy my new monitor and not just 1/3rd of the screen or less.

    You can see that there is a VERY wide margin on either side- and this was already enlarged substantially with control/scroll which did not widen it at all (as it does on Google Chrome) only enlarged the miniscule text. I opened the exact same page in Chrome and widened it to fill the whole screen...

  • I upgraded from 3.6.13 to Beta 4.0 and now Firefox will not open at all I tried to uninstall to start again but it will not uninstall either it does nothing.

    I uninstalled Beta 4 and re-installed 3.6.13 now Firefox will not open at all I tried to uninstall to start again but it will not uninstall either it does nothing, I have been using Firefox for a long time but cannot resolve this problem can anyone help and give me a solution please. As I use Firefox as my web browser it is very frustrating.
    The fact it will not uninstall appears to be something completely new as nobody I know who uses Firefox has ever encountered this in the past.

    Did you check your security software (firewall)?
    A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox 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.

  • Firefox will not open ANY site. Wont work AT ALL. Nothing seems to be working.

    Firefox will not open ANY site. It worked last night, but not today. I uninstalled it many times, didn't worked. It displays the screen that says "unable to connect" yet chrome and explorer both work. I have disconnected and reconnected a few times, restarted my laptop, neither of those worked either. I have also tried turning "safe mode" off after re installing firefox, but again, that did not work. I need help :(.
    Although, before this, firefox was not letting me use voice recording sites or any site that let me watch television online. It would load the commercials, but not play the episode. It wouldn't even let me upload pictures to photobucket. However, it worked using chrome or explorer.

    Looks like a bunch of people have this problem. Anyone got any ideas to fix this???

  • Firefox will not open. Hangs at "connecting" stage. Non-responsive even to process shut-down via task manager.

    Starting yesterday, Firefox will not open at all. It hangs at the "connecting stage." For hours. It will not shut down even using the task manager for applications or processes, and it locks up virtually every other application. I thought I managed to save an open Word document yesterday - it looked like a slow, but normal save during the Firefox hang, but the document was empty when I restarted my computer.
    Even though my machine is not pentium 4 based, I tried starting using the Windows XP/M configuration, I downloaded and re-installed (over the top of) the existing version, I verified that no Mozilla processes were running before trying to start Mozilla, and tried creating a new profile. Absolutely no success. Every time (of the dozens) I have tried to start Firefox I have had to force a hard shut-down to get out of the application. I have now unpinned Firefox from my task bar because I keep forgetting and hitting it by reflex.
    I am running version 11.0 (at least that is what I just downloaded - I am not positive what I was running yesterday). My system is Windows 7 Home Premium, Intel Core i3, 2.4 gHz, 4 GB RAM, 64 bit OS.
    Next option is to restore to a previous version. If that doesn't work, I will uninstall and start over from scratch.

    A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

  • I have no navigation bar and firefox will not open in safe mode to reset to default config. Reinstalling doesn't work. Any help please.

    I have no navigation bar ever since I closed it to gain more space on the screen. It won't re-open. Firefox will not open in safe mode, but opens immediately in normal mode with the new improper config, so I cannot reset to default config. I erased Firefox and re-installed and it still opens with the same faulty config. Why does Firefox not give me the safe mode dialog box, why can I not re-open the nav bar, and how can I do these two things, please? Firefox is currently unusable for me without a nav bar and without access to the default settings in safe mode. I cannot research the extensions I'm running since I have no nav bar to go to Tools, Add-ons, Extensions.

  • Firefox will not open unless I run it in compatibility mode (Windows XP SP 3), run it as an administrator, or launch it immediately after a reinstall (the reinstall thing only works once.) How do I fix this?

    This morning, Firefox crashed. After this, when I click the Firefox icon, the hourglass appears and then nothing happens. Firefox does briefly appear in the task manager when I do this.
    I tried rebooting. I tried reinstalling multiple times. (Firefox will run when I select "Launch Firefox" from the installer. Then the problem occurs again.) I tried safe mode. I have found that Firefox will work if I select Windows XP compatibility mode from the icon properties menu or if I run the program as an administrator. When I do this, Windows asks me if I want a program to be able to make changes to my computer.
    I have noticed that a Windows Error Report is being generated each time Firefox will not open.

    You may need to delete the Firefox program folder before (re)installing the latest Firefox.<br />
    In case you still have problems after installing then check your security software.

  • Firefox will not open at all. Google Chrome main browser.

    Google Chrome my main web browser with Comcast as home page.
    Now Firefox will not open at all. What do I do. Delete Firefox and reinstall is what I think?

    Yes, i would try reinstalling Firefox first.
    A few other basic trouble shooting things you can try is this:
    Run all Windows Updates, install all needed service packs, etc.
    Update your graphics driver (Firefox uses your graphics card for some rendering, and an out of date graphics card driver can cause problems. [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
    Update all your plugins (Flash, Java, etc.): [http://www.mozilla.org/plugincheck/ http://www.mozilla.org/plugincheck/].
    Download and Install MalwareBytes Anti-Malware, run a full Scan. [http://www.malwarebytes.org/ http://www.malwarebytes.org/]. This helps check that there are no viruses on your computer causing issues. You can uninstall this program after you clean off any infections.

  • Firefox will not open. it says to proxy server is refusing connections. please advise

    firefox will not open. the window says that the proxy server is refusing connections.

    go to '''TOOLS''' then '''OPTIONS''' then '''ADVANCED''' then '''NETWORK''' tab then '''SETTINGS''' tab and '''select the options NO PROXY''' click '''OK''' and '''OK''' again in the next screen. With that you have disabled the proxy settings.
    if you like to '''not''' disable the proxy settings choose :
    '''Auto-detect proxy settings for this network'''

  • Firefox will not open on my computer the majority of the time. If I shut down and restart it will work sometimes, but not always. This started recently in the last two weeks. Today is June 12th 2011.

  • Firefox will not open after attempting to upgrade to v5, sys restore didn't help

    Was running 3.6 with no problems, but trying to upgrade today apparently broke it. The upgrade failed for some reason (the old .exe is still the only one in the Firefox folder & I can't find any files newer than April 2010 in there), but no matter how I try to run it, nothing happens - Firefox will not open, period. I tried reverting to last week with sys restore, scanning for malware with Malwarebytes, but still nothing happens. I'm using WinXP 5.1 media edition SP2 (yes, it's been around a few years but it works for me). I'm now using Chrome which seems to run just fine, tho I miss all my plugins.

    Hi lwhealon
    try from Start > Run > and type to check 1 of :
    firefox -safe-mode
    "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode '''or'''
    "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -safe-mode
    (to enable the Run box in win 7 see: [http://blogs.msdn.com/b/tims/archive/2006/09/18/windows-vista-secret-3-bringing-back-start-run.aspx enable Run box win 7] )
    also check if [http://kb.mozillazine.org/Firewalls Firewall] or/and other security software blocking firefox start (like ad-blocker, web-accelerator etc).
    [http://kb.mozillazine.org/Kill_application With Firefox completely closed] (probably because you can not start it), open the [http://kb.mozillazine.org/Installation_directory application folder] (by default, C:\Program Files\Mozilla Firefox on Windows) rename firefox.exe to firefox1.exe, then double-click firefox1.exe. If Firefox runs without problems, it could indicate that your firewall is blocking Firefox.
    good luck
