Firefox will not open or uninstall even after following instructions

iv tried uninstalling in safe mode but nothing works

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.

  • Firefox will not open at all, even after rebooting & re-installing - IE opens normally - what can I do?

    I've used Firefox since version 3 - really like it compared to others.
    This morning, after booting up Firefox wouldn't open. It worked when the PC was shut down last night. The eggtimer comes on briefly, then nothing. Internet Explorer works fine, as does Mailwasher (for email) and MS Outlook, so it's not an internet problem.
    I'm running XP Service Pack 3 (no, really, still), with Webroot Secure Anywhere internet security.
    I've tried rebooting - no effect
    I've tried removing, rebooting, and reinstalling - no effect
    I've tried launching it from a link within a mail message - no effect
    I've tried launching it from the Start-Run line with the ~p option as in your FAQ - no effect
    I've tried re-installing Adobe Flash Player, Java, Shockwave, etc..
    The closest I've got to something to go on is when trying to launch a console from Webroot, when I got "Browser launch error 1073741819" - but this could be a Webroot error code.
    I'm not sure what else to do - almost all your FAQ's assume you can get into the program.
    The only thing I can think is that webroot removed a threat this morning, but I can't find any saved scan log as to what it was - clutching at straws, maybe that had something to do with it?
    Maybe this is linked, but i'm having to write this on a different PC because the Mozilla webpages don't display properly in IE (all the other sites I can find display normally) So the installed plug-ins won't reflect what I have on the PC in question

    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 4.0 will not open at all. It shows that the process is running in the task manager but will not open the window even after closing the prcess and restarting.

    I have had firefox since an earlier 2. version and have been able to upgrade as normal. After the installation is done it will not open at all. I have restarted and even uninstalled all previous version .exe and still nothing. I am using windows 7 OS. I am still running 3.6.8 and would love to see the new one running on my laptop.

    hello, this crash is caused by Websense Endpoint security software that is running on the system. please try to install all the updates for this program that are available...

  • Firefox will not open in Vista SP2 after installing software for a Brother MFC printer.

    I have 7 computer network. All the machines are running Vista SP2. I recently purchased a Brother MFC 9325cw, and installed the printer/scanner drivers as well as a program called scansoft paperport on each of the machines individually.
    I left out the some of the bulkier aspects of the driver package, namely the brother control center because it seems to eat up a lot ram at start up.
    Since I have installed the printer driver on my computers, several of them will not open firefox.
    I have tried re-installing firefox on one machine so far to no avail.
    Next I will try to re-install the brother software. Has anyone else encountered this problem before?

  • Firefox will not open at all. After click the hourglass comes up and then goes away and nothing happens at all. Nothing will load past the desktop. I cannot get into firefox at all to enable anything or disable anything.

    When i click on the mozilla icon on the desktop the arrow will spin (VISTA) and will then disappear. Mozilla will not enable or even pop up or anything. I am still looking at the desktop and not mozilla. I lick on the icon many times and nothing ever enables, still stuck looking at the desktop and no Internet. Not to bring up your rival, but IE will open half way and then say not responding and will freeze and i must restart the computer every time. I have to use opera now because IE and Mozilla will not enable and Mozilla wont even pop up or enable or anything...just the desktop and no net. ONCE AGAIN MOZILLA WILL NOT ENABLE, SO I CANNOT GO TO TOOLS OR ANYTHING.

    I have exactly the same issue. After FF upgraded on its own to version 5, it won't open from start menu, taskbar, desktop icon, or even by pressing firefox.exe in program files directory. It does so by pressing a link at msn messenger, inside Outlook etc.
    Disabling all addons, didn't help. Moreover, I can't start FF in safe mode or start profile manager (Start > Run> firefox.exe -ProfileManager).

  • Firefox will not complete the installation even after several attempts of rebooting the computer.

    I downloaded the Firefox 9.0.1 upgrade but it will not complete the installation on my computer. Everytime I try to remove the program, it tells me to reboot the computer to finish the installation. After several reboots, the same error keeps coming up.

    Try to run the Firefox program once as Administrator (right-click firefox.exe: Run as Administrator).
    If that doesn't solve the problem then remove the Firefox program folder (C:\Program Files\Mozilla Firefox\) to do a clean reinstall.
    Download a fresh Firefox copy and save the file to the desktop.
    *Firefox 9.0.x: http://www.mozilla.org/en-US/firefox/all.html
    Uninstall your current Firefox version, if possible.
    *Do NOT remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.
    Remove the Firefox program folder before installing that newly downloaded 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.
    *http://kb.mozillazine.org/Uninstalling_Firefox
    Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

  • I need help. My Firefox will not stop doing this even after i reinstalled. I will shut down firefox and when I open it back up it shows the previous website.

    Please Help. This is starting to anger me. I Reinstalled and everything.

    You should update your outdated Firefox 13.0.1 version to the current Firefox 17.0.1 release.
    I'm not sure what you mean.
    Do you mean that Firefox always opens the web pages that were open when you closed Firefox even if you set to open with the home page or a blank page?
    Make sure that Firefox closes properly and that there isn't a hanging Firefox or plugin-container process left in the task manager.
    *"Hang at exit": http://kb.mozillazine.org/Firefox_hangs
    *"Firefox hangs when you quit it": https://support.mozilla.org/kb/Firefox+hangs
    Use "Firefox/File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit") to close Firefox if you are currently doing that by clicking the close X on the title bar.
    You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox Profile Folder that store session data.
    Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox Profile Folder.
    *Help > Troubleshooting Information > Profile Directory: Open Containing Folder
    *http://kb.mozillazine.org/Profile_folder_-_Firefox
    Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

  • Firefox will not open a webmail site after upgrade

    Since I upgraded to Firefox 4.0.1 yesterday I cannot access my work email via Lotus Domino Web Access. Every time I try, the process begins as usual, asking for user name and password, then proceeds to the main page and begins to load but stops and gives this message: Domino Web Access Warning: Sorry, we were unable to process your request at this time. If you are unable to continue working in your mail file, please dismiss this warning and then select View, Reload from your browser's menu.
    I can access the webmail site via my laptop, on which I have not upgraded Firefox, or via Internet Explorer on the desktop computer on which I'm having the problem.

    What is opening instead of your Homepage?

  • 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.
    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.

  • 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)?

  • Firefox will not open after unlocking Sempron

    After upgrading to a new motherboard and unlocking Sempron processor, Firefox will not open. I have tried Firefox (safe mode) and rolled back to a previous version, but to no avail. It worked fine when I ran the Sempron 140 as a single core (even overclocked to 3.17ghz) on Biostar A785GE motherboard. I cannot find a crash ID to link to.

    Maybe you restored to a version of Firefox that crashes or still have a virus problem.
    (irrc some Firefox versions specifically had problems after Windows restores)
    Follow up checking for malware and then try re-installing Firefox. I would also suggest you make a copy of your [[profiles|profile]] including all folders and sub files and put it somewhere safe as it may assist in restoring your bookmarks and information.

  • 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.

    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.
