Why does firefox tell me to close open window before it can open

when I try to open firefox get message "browser needs to be closed before opening"

On a Mac, Firefox 4 is a 64 bit application.<br />
Not all plugins support 64 bit and if not then you need to start Firefox in 32 bit mode to use that plugin.
# Close Firefox
# Open the Applications folder in Finder
# Right click or control-click the Firefox.app icon
# Select "Get Info"
# Select or Deselect "Open in 32-bit mode"
# Close the "Firefox Info" window
# Restart Firefox

  • Why wont firefox load after i close the window ? it tells me it is already running in the background and to close that window before opening again. took 10 tries before it would load again !

    this has been going on for some time. 2 months maybe. i can hear the hard drive winding up/down after i close the window, and then comes a long narrow blue window stating what i have written.

    See
    * [[Firefox is already running but is not responding]]
    Try closing any running instances of ''firefox.exe'' (and plugincontainer.exe) using something such as Task Manager. That should allow you to then restart Firefox.
    As for iLivid. Possibly it also has associated apps or extensions with names not including the word iLivid. Looking at their own FAQs there are instructions to remove iLivid using the Windows Control panel, and mention of other bundled software that you may wish to remove. It seems it is more of a nuisacne rahter than out and out malware.
    * see http://www.ilivid.com/faq.htm (page scrolls for more info) but includes:
    How do I uninstall the software?
    The software can be removed in a simple was like any other software:
    Go to the Windows Start menu and then to Control Panel > Add/Remove ("Programs & Features" in Vista & Windows 7) and click "Remove" next to the software name (e.g iLivid Download manager / Windows iLivid Toolbar ).
    During the installation bundle software are offered, each can easily be removed following those instructions: Uninstall Yontoo Addon , Uninstall Search Toolbar (powered by Bing) or Uninstall Babylon.

  • Why does Firefox tell me the page I am on page contains unencrypted info when on https address

    <blockquote>Locking duplicate thread.<br>
    Please continue here: [[/questions/849608]]</blockquote>
    When I used a Safari "https", I was never warned that I had requested a page containing unencrypted information. Why does Foxfire warn me when I am on a supposedly secure link with Bank of America? Why does it say that info I enter can easily be read by 3rd parties? Thank you, David Verch

    That is usually by doing a request for images or other files via an insecure HTTP link.
    You can test that with the Live HTTP Headers extension if you want to verify that.
    *Live Http Headers: https://addons.mozilla.org/firefox/addon/live-http-headers/
    Open the Live HTTP Headers extension via the Tools menu and open the Generator pane.<br />
    Tick all the boxes in the Show panel at the right and do a hard reload via "Command + Shift + R"

  • Why does Firefox require a Plug In for Windows Media 11 and it doesn't exist for Windows 7 Ultimate 64 Bit

    I wanted to listen to an Internet Radio Station and every time I clicked the listen now button on that site, Firefox tells me a Plug In is required for Window Media Player 11 so I follow the link to be told it is a manual download. When I get to the download site, I cannot find a Plug In download that is suitable to Windows 7 Ultimate 64 Bit so, I cannot listen to the radio station I want too and would like to know if there are any other options.

    You can use the new WMP plugin for XP/Vista as well on Windows 7 with WMP 11.

  • Why does firefox 3.6.15 close so slowly and erratically?

    '''bold text'''When I close down the web browser after viewing any web site, the window closes very slowly and erratically.

    Well, this may not help anyone else, but I figured out my issue.
    After reinstalling 3.6.4, it too was doing the same thing, using 25% CPU consistently, unable to move the window around, etc.
    As bizarre as it sounds, this seems to have been an issue with having a tab open playing flash video during an update/install.
    After 3.6.4 was doing it as well, I closed the justin.tv tab and restarted 3.6.4, opened justin.tv back up and it was fine using 2-4% CPU or so instead of 25%. Window can be moved around again too.
    Downloaded the full 3.6.6 installer, closed the jtv tab, reinstalled 3.6.6, launched, and reopened a tab for jtv... fine still using 2-4% CPU tops.
    Very bizarre. Nothing else changed during any of this other than whether I had JTV open and playing video during the update/install and subsequently if it would be loading as soon as it restarted after the update/install.
    After the initial startup, I can close and reopen Firefox as much as I want with the JTV tab open and playing and it has no further issues.
    Weird.

  • Why does Firefox tell me it's not the default browser?

    When I start Firefox, or when I go to the options system and check, Firefox 8 tells me it's not the default browser. Yet, if I close it, and go to some program such as Excel and type in a URL then click it, Firefox opens it. Any idea what's wrong?

    That means that not all Firefox settings as default browser are set and that some are missing

  • Why does Firefox get hung up, when opening new pages? I've tried disabling plugins and extensions to no avail.

    Initially, when I open Firefox everything opens very quickly. However, after several minutes it gets hung up when opening new pages. I have close the browser and reopen it to start over. But each time it does the same thing. Works well at first then poops out. The trouble started yesterday. Before then, I never had any problems.
    I've tried disabling all the plugins and extensions, but it doesn't make any difference.

  • Why does firefox ask which program to open with and not start as automatic default? Why does it not go to home page?

    When I click on firefox, it asks which program I want to open Firefox with, then asks me to download files. It does this every time I try to open Firefox. It does not automatically default to my home page as well. How can I change this back to an automatic process?

    See item #31 (#tabslost) in the following
    -- you can turn option on at end and then tabs will be restored whether you do or don't or don't restore tabs at end you still have the same chance through the History menu. to restore your previous session and then to restore previous windows

  • Why does Firefox tell me that I don't have the latest version of Flash but Adobe tells me that I do?

    Firefox keeps telling me that I have to upload a newer version of Adobe Flash. However, Adobe tells me that I have the latest version. Also, Google Chrome lets me see pages that Firefox will not load because it thinks I don't have the right version of Flash! Any ideas on how to resolve this? Thanks in advance.

    Which version of the Flash player do you have?

  • Why does Firefox (after the latest update) open an additional tab "What's new"? It causes my laptop to crash, including my "Session restore"

    Mozilla Fireox Session Restore fully functioned. However, not after latest update (10.0.2). It takes a lot time to load the (additional tab) page "what's new?" / "Firefox add-ons" after which the script running Session Restore fails.
    Only occurs after (re)starting laptop.
    How do I remove this addional tab ?
    It's irritating.

    Hi Murdock_1,
    You should look at [https://support.mozilla.com/kb/Firefox+has+just+updated+tab+shows+each+time+you+start+Firefox this article about that specific issue] and the article [http://kb.mozillazine.org/Preferences_not_saved Preferences not saved]. These should give you all the information you need!
    If that doesn't work:
    # Type about:config in the address bar
    # Click ''I'll be careful, I promise'' if prompted
    # In the Filter input field type ''startup''
    # Double click on startup.homepage_override_url
    # Delete the text string and click ''OK''
    # Close Firefox and reopen the window to verify that it has worked.
    Hopefully this helps!

  • Why does Firefox keep freezing/locking up system (Windows 8)?

    I just recently decided to switch to Firefox from chrome because I was sick of chrome's adblocker never working. Unfortunately, whenever I use Firefox, it will randomly freeze my entire system so I have to do a forced shutdown by holding the power button. When it freezes I can't even move my mouse let alone open task manager to end Firefox. Any help is greatly appreciated because I really like Firefox but it is annoying having to keep restarting my computer every 20 minutes or so. I notice that usually freezes when watching videos on YouTube, although not always. I am using Firefox 30.0 with Windows 8
    System specs:
    Dell Inspiron 15r Special Edition
    Intel Core i7 processor
    Windows 8 x64
    8GB RAM
    750GB Hard drive
    2GB AMD 7730M

    Something similar happened to me at one point, and I found out that one of my RAM chips had gone bad. The way I found out was from scanning with Memtest86. Its an ISO file that you print onto a CD, then the computer will boot from it. After replacing the chip it has been running smoothly ever since.

  • Why does Firefox use an unsigned server connection request before conneting to internet?

    <pre><i>Locking duplicate thread.
    Please continue here: [[/questions/979016]]
    </i></pre>
    When an application wants to make a connection to a server for internet or updates it presents a signed server connection request. Recently, in order to get Firefox to connect to the internet, I have to approve unsigned server connection requests even though I know unsigned requests are open to abuse from hackers. How can I get Firefox and other applications from reliable suppliers to issue SIGNED server connection request? Please help. Regards.
