Why will FireFox not work on my system? (Windows 7) Help.

This is the error message I receive when attempting to open FireFox
"Your Firefox profile cannot be loaded. It may be missing or inaccessible."
I do not like using any of the "Brand-X" browsers and I wish to have FireFox working again. My operating system is Windows 7.
Please help. I do not know what to do.
Thank you,
Mark S. Pannill

Could you try starting Firefox in the Profile Manager and create a new profile? Here are the steps:
Start up in the Profile Manager using Start > search box (or Run):
firefox.exe -P
This should display a dialog. Normally, at least one existing profile is listed, but it sounds as though yours will be empty.
Click the Create Profile button and choose any name you like for the profile. Skip the option to customize the folder location and save your new profile. Then select it in the box and start Firefox in that new profile.
Does it run?

  • Why does Firefox not work here in China anymore, since January of 2015?

    I have used Firefox for years, as the fastest and most reliable browser for me, esp in China... not anymore! Last month (unknown to me) a hijacker called Vosteran took over my Firefox browser. I finally realized it and got it cleaned up using Malwarebytes anti-malware, and downloaded a new Firefox... now SAME problem exists, even with Vosteran removed!
    Firefox will not allow me into ANY normal sites, saying they don't have the proper security code. This includes my Yahoo front page, email account, ESPN and other common sites that are certainly NOT dangerous. So, WHY does Firefox not work anymore? It is useless to me here in China the way it works now.

    hello rickinchina, first please make sure that the '''date, time & timezone''' are set correctly on your system and that firefox is set to directly connect to the internet (that's the "'''no proxy'''" setting in the firefox ''menu ≡ > options > advanced > network > connection - settings...'').
    if this doesn't solve the issue (or it is already set properly), a possible solution depends on different factors:
    * what is the '''error code''' shown under ''technical details'' on the error page?
    in case the error code equals ''sec_error_unknown_issuer'', please attempt to add an exception on the bottom of the error page (but don't do it for real) and inspect the certificate (see the screenshot attached for instructions):
    * which '''issuer information''' does the certificate contain?
    please report back with those two pieces of information. thank you!

  • Why will ituntes not work on my surface tablet?

    I have downloaded iTunes twice to my tablet and it says it cannot run iTunes and redirects me to the app store on my windows surface RT tablet32gb

    You should read about Windows RT, it is not a 'standard Windows computer' but a version created for ARM (a different platform), as such many applications do not work with ARM on Windows a.k.a 'Windows RT'.
    https://en.wikipedia.org/wiki/Windows_RT
    Unless Apple make a version for Windows RT it seems unlikely that iTunes will ever work, sorry you will have to find an alternative in the Windows App store.

  • Why will firefox not start on my laptop? can't uninstall or open the profile manager either. it simply does not run. it used to work fine until i had to restore my system.

    had firefox 4.0 & have been a user of firefox for a few years now. never had any problems. had to do a system restore after my computer detected a virus of some sort & i couldn't do anything. the virus kept popping up a bogus add for me to buy an antivirus program. had to restart laptop in safemode to initiate the restore. ever since then firefox has not opened. can't even uninstall it or open the profile manager. anything that has to do with firefox will simply not run/open at all. i'm stumped.

    System restore can cause problems as well as solve them, it has probably completely mucked up your Firefox installation.
    Try deleting your Firefox installation directory, the default location on 32 bit Windows is C:\Program Files\Mozilla Firefox\
    Now re-install Firefox, it should pick up your current profile folder so you should not lose your bookmarks, passwords etc.

  • Why will Firefox not start on my windows laptop but it says it is open in background

    since last update, firefox will not start even after repeated attempts. It is apparently open as i cannot delete it from the laptop untill I restart laptop.
    I am running Windows 7 and i run Thunderbird successfully on my machine. I am forced to use IE to get onto the internet.

    Does Firefox not start in Safe Mode?
    * Click the Windows logo orb on the taskbar to bring up the Start Menu.
    * In the search box, type firefox.exe -safe-mode and press Enter.
    * If the little Firefox Safe Mode window pops up, click the Start in Safe Mode button.
    * For more details, see [[Troubleshoot Firefox issues using Safe Mode]]
    If Firefox doesn't start in Safe Mode, does the profile manager start? If yes, create a new profile and try starting Firefox in that profile.

  • Latest windows 7 patches and firefoz 18 - firefox not working properly - shows stacked windows and does nothing

    Jan 10 windows 7 patches, plus new firefox update today. Now firefox starts up and shows multiple, stacked window frames and "firefox not responding" messages on top border. after multiple firefox screen flashes (minutes of time), firefox may eventually display normal windows/frames. Selecting new site, firefox goes through same activities. Startup site is www.baynews9.com, then try going to www.cnn.com

    The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
    Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
    To Reset Firefox do the following:
    #Go to Firefox > Help > Troubleshooting Information.
    #Click the "Reset Firefox" button.
    #Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
    #Firefox will open with all factory defaults applied.
    Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

  • Why will Firefox not download on my computer?

    I have Windows, and have clicked the Firefox download button SEVERAL times....then I will click Run. It loads its 60 second thing and then nothing happens after that. I have gone to the support forums and tried all the other websites (ninite etc.) and suggestions for that and nothing works. Please help!

    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!

  • Why will firefox not allow me to change the home page

    I am running firefox on vista laptop and since one of the upgrades of firefox I have now a automatic homepage of http://www.searchqu.com/406. I have tried to change it several times to various pages and it does not hold the address, not even a blank one. This happens even if I only close the browser for a split second. Can I please get some advise on this matter.
    Many Thanks
    Simon Donnelly

    Type '''about:config''' in the Location (address) bar and press the "Enter" key. When you see a warning, click '''I'll be careful, I promise!''' button.
    * Preferences that have been modified are shown as '''bold (user set)'''.
    * Preferences can be '''Reset to the default''' or changed via the right-click context menu.
    -> In the '''Filter bar''', type '''searchqu'''
    * This will show all '''searchqu''' related preferences.
    * '''Reset''' all '''searchqu''' related Preferences to their Default values (right-click a preference and click '''Reset''')
    -> Close the '''about:config''' tab and then Restart Firefox.
    Check and tell if its working.

  • Why will minecraft not working on new iMac?

    I just upgraded from on old iMac.  Dealing with unhappy kids becuase the minecraft game they loved won't work on the new one. 
    I've installed Java for Lion.  I go to the minecraft site and try a single player game.  We get application errors.
    I suppose its an older game that is not compatible with Lion, right?
    I see I can purchase a download for 20 euros.  Should that work?
    Thanks for any advice.

    You will need to go to their site and troubleshoot and see if it is compatable with Lion.
    Good Luck

  • Why will Firefox not open links on website I create with Dreamweaver?

    When i create a link to another web page, I cannot open the link in Firefox. I can in IE, but not in Firefox. I am working in Dreamweaver CS6

    Such code should be working.
    Do you see the correct URL popping up at the bottom of the screen when you hover such a link.
    If that isn't the case then right-click the link and use Inspect Element to check what Firefox sees at that position.

  • Why will Firefox not open Windows Live when Internet Explorer will?

    As above

    Hello,
    '''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
    ''(If you're not using it, switch to the Default theme.)''
    * On Windows you can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * On Mac you can open Firefox 4.0+ in Safe Mode by holding the '''option''' key while starting Firefox.
    * On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
    * Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
    [[Image:FirefoxSafeMode|width=520]]
    ''Once you get the pop-up, just select "'Start in Safe Mode"''
    [[Image:Safe Mode Fx 15 - Win]]
    '''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
    ''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
    ''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
    Thank you.
