Firefox will not start, have repeatedly reloaded it form your site, on my XP (SP£) PC?

Desktop icon / exe file will not start Firefox. Have repeatedly downloaded it & works for a short time & then fails. Also experiencing screen freezing, having to restart PC - are these connected?

A possible cause is security software (firewall,anti-virus) that 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 will not start, have to reinstall firefox

    only happened to me after i switch to comcast and use norton anti virus.

    Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
    '''Note:''' You might want to print these steps or view them in another browser.
    #Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
    #After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
    #Delete the Firefox installation folder, which is located in one of these locations, by default:
    #*'''Windows:'''
    #**C:\Program Files\Mozilla Firefox
    #**C:\Program Files (x86)\Mozilla Firefox
    #*'''Mac:''' Delete Firefox from the Applications folder.
    #*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
    #Now, go ahead and reinstall Firefox:
    ##Double-click the downloaded installation file and go through the steps of the installation wizard.
    ##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
    Please report back to see if this helped you!

    Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
    Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
    It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

  • Firefox will not start, after reboot.

    For a few months now Firefox will not start after I reboot my computer. In order to get it to start I click the exe then must go into task manager kill it, click the exe again, kill it again then, from there it will typically start, but sometimes it may take one or two more trys. When clicking the exe firefox will appear in the task manager under processes but will will start with ~7% CPU usage, then quickly drop to zero every time until it does actually open and start. I have ran a full system recovery and started anew after reinstalling mozilla several times failed to fix the problem. I run virus and spyware checks often and come up clean, and also run Chrome as a default browser.
    == This happened ==
    A few times a week
    == Around the time 3.5 was released

    Hello Tom.
    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.

  • After upgrading to 27, firefox will not start. Saw an error message during the upgrade process.

    After upgrading to 27, firefox will not start. Saw an error message during the upgrade process but cannot remember.
    Tried to run firefox.exe -P but receive error message:
    XML Parsing error: undefined entity
    Location: chrome://mozapps/content/profile/profileSelection.xul
    Line number 18, Column 1:
    <dialog
    ^
    Running on Windows XP SP3. No problem whatsoever before upgrading to 27. Sending this from Chrome as I cannot open Firefox at all.

    Thanks jschaer2000: after starting it once in safe mode, I closed Mozilla and tried several restarts in normal mode. So far, all worked:-)
    Thank you very much again.
    Still the automatic update process bothers me: it took me several days to discover the reason to the malfunction, since when I removed the problematic version from Add and Remove Programs, I didn't pay attention at first that it was another version, not v26 which I installed from my folder.
    In addition, I like to save the installation files before I run new programs and if I didn't have v26 exe file, I couldn't have operated Mozilla at all. Not that it was fun to remove and install again each time v27 didn't react, but it was better than nothing, I still prefer Mozilla over its competition.

  • Firefox will not start and open a website from a Thunderbird email link. It will go to a link from Thunderbird once Firefox is open, but will not initially start Firefox and proceed to open the Thunderbird email link.

    Firefox will not ''start'' and open a website from a Thunderbird email link. A link from Thunderbird will open once Firefox is ''already'' started, but will not initially start Firefox and proceed to open the Thunderbird email link.

    I also have this problem. I cannot open links from a discussion board I frequent nor can I open links from my email. Also after opening my email, I cannot go to any other sites except my home page. I can then go no where else.
    When I close Firefox and try to reopen it, it does nothing! I have to bring up the Task Manager and end the Firefox process before I can get back in.
    To the best of my knowledge, this problem started with the new update to Ver. 3.6.9. I am running Windows XP Media Center 2005

  • Firefox will not start, even in Safe Mode. Evidence suggests that this is due to an incompatibility with the latest update of Java.

    Firefox will not start in WinXP. (I am sending this from an alternate browser.)
    I believe that this is due to some incompatibility with the latest update of Java. I believe that one of the tabs from my previous session included a Java application, and this is causing the difficulty. In recent days, since the last update of Java, I have had difficulty in loading linked pages with Java applications into Firefox, and have needed to switch to a different browser to do this.
    Now I cannot even start the browser, presumably due to the presence of a Java application on one of the restored tabs.
    When I now try to start Firefox, my ZoneAlarm security s/w presents the message "Java(TM) Quick Starter binary is trying to access the Internet." I click "Allow", but Firefox will not start. If I click "Deny", the same result. The same thing happens when I try to start Firefox in Safe Mode, I cannot even start Firefox in Safe mode.
    == This happened ==
    Every time Firefox opened
    == after recent update of Java

    You can try to disable the Java Quick starter and the Java Console extension in the Control Panel > Java.
    Control Panel > Java > Advanced tab > Miscellaneous >Java Quick Starter (disable)
    You can also disable the Java plugin in Firefox: Tools > Add-ons > Plugins
    See [[Troubleshooting extensions and themes]]

  • Firefox will not start any more.

    Firefox will not start. (reported as a hang)

    Try Application > Utilities > Activity Monitor and look in the Process Name column to see if there is a version of Firefox there.  If so, select it and then hit the Quit Process icon.
    Restart Firefox.
    Recently, Firefox has repeatedly started hanging on my 10.7.2 iMac.
    If that is not it, try Carolyn's suggestion.

    It sounds like you may have a problem caused by an extension (maybe that avery toolbar)
    [[Troubleshooting extensions and themes|Try the instructions in this article]] - begin by putting Firefox in Safe Mode.
