Mozilla Firefox won't start and it freezes my laptop whenever I try to open it. What do I do?

Last May, I was using my laptop without its battery and it was only plugged to avoid damaging the battery since it was already fully charged. I was browsing the Internet using Mozilla Firefox when a brownout occurred. After the electricity came back, I tried to open Mozilla Firefox, but then after a few seconds, it froze my laptop. I tried to uninstall it for a number of times, downloaded other versions, etc. but it still kept on freezing my laptop.

I'm not sure if I'm understanding but if I am then I'm not sure why you are turning your Wi-Fi off and on. It should automatically connect and use your Wi-Fi when it is available and use your cellular data connection when Wi-Fi is not available. I haven't turned either off ever. However, more to the point of your current problem, the following has some troubleshooting steps that may help: http://support.apple.com/kb/TS1398

  • There's an "updated.app" laying in Firefox package. Since firefox won't start and "updated.app" will, is it safe to replace firefox package with it?

    After last update to last version, FF was running fine before a hardware restart.
    Since then it won't start and profile manager either. No error message pops up and console window doesn't trace any event.
    firefox package contents an "updated" package likely created by last update.
    Will i loose my settings or run into any kind of problem by replacing firefox's package with the so called "updated" one?

    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.

  • Firefox won't start, and I cannot download the new version as it keeps saying 'unspecified error' when I try

    We (my wife and I) downloaded the new version of firefox, but found that it was being very jerky and slow and just didn't really like how it looked. My wife did a system restore on our computer to see if that helped, and since then firefox hasn't started at all - if we double click on the icon, it looks like it's doing something and then it just doesn't open. Whenever I try and download it again it comes up with 'unspecified error'. I've tried deleting all the firefox program files from my computer first, but there is one file in conponents that it won't let me because I need administrator permission. It doesn't seem to make any difference anyway.

    Using "System Restore" can cause your Firefox installation to get corrupted because not all files are restored (only files in a white-list), so be cautious with using System Restore.<br />
    You need to (re)install software that was affected.<br />
    Remove the Firefox program folder (C:\Program Files\Mozilla Firefox\) before reinstalling a freshly downloaded Firefox copy to do a clean install.
    You can find the latest Firefox release in all languages and for all Operating Systems here:
    *Firefox 11.0.x: http://www.mozilla.org/en-US/firefox/all.html
    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 have files that freeze my programs whenever I try to open ANY file. Is there a way to find the exact files causing the crash?

    I have files that are freezing my programs (adobe; after effect and photoshop, as well as maxon cinema 4d). Whenever I try to import ANY file from within the program it doen't even let me select the file I need before freezing. I have moved all files off my desktop and into my dropbox, and it now allows me to import files/search for files on the desktop but NOT dropbox, once I go to dropbox it freezes again. I am assuming there are files within dropbox now that are crashing my programs. The problem is I have a lot of files in there and would like to remove the corrupt ones so that I can use my programs without freezing. Is there a way to find the exact files causing the crash?
    This has happened a couple of times and each time I have to move all my files off my desktop, so there must be a type of file doing this, I just don't know what files they are.

    ANY help would be greatly appreciated! It is making it really hard to get work done. THANKS!

    This error sounds to me like you have/had BootCamp Windows installed and then removed, posible ?
    If so (and even if not so), try restating your MBA while holding down the alt/option-key until you get to the Boot Selection Screen.
    Choose to boot OSX.
    Once in OSX go to System Preferences then Startup Volume and set your OSX to be the default.
    Hope it helps

  • Firefox won't start and give message "De verbinding werd geherintialiseerd.

    I tried first to fix the problem by resetting Firefox.
    When the trouble continue I install the version 23.
    This not working and the popup still appaers "De verbinding werd geherintialiseerd".
    I can't get on internet with Firefox.
    On Internet Explorer, from where I've contacted you, there's no problem, but I prefer Firefox.
    Could you help me?
    In the other case I must use IE.
    Thanks!

    hello fred, often such issues are caused by a firewall/security software which doesn't recognize & therefore blocks firefox: [[Fix problems connecting to websites after updating Firefox]]

  • After dowloading Mozilla Firefox, I get nothing but a google search bar when I try to open Firefox

    What details? My problem is that I do not have a home page as such; I have nothing but a google search bar. Can I uninstall; reinstall without the google thing?

    '''about:home''' is the new Firefox 4 homepage, and all it really has is the Search Container, of which Google is the default. It is very easy to set your choice of a homepage or to set the old Firefox Start Page which was this: http://www.google.com/firefox

  • HT203175 The latest version of iTunes freezes my computer whenever I try to open it. Needless to say, this is infuriating. I have Windows XP, which should support the latest version. I am particularly exasperated, because iTunes compelled me to download.

    iTunes compelled me to download the latest version, before I could complete a transaction (which, needless to say, was botched). I have Windows XP, and I cannot open iTunes now without freezing or crashing my computer. This is utterly frustrating, since I can't even play any holiday music, much less update my iPod.
    Can I uninstall, and reinstall the older version? I do not need all the bells and whistles, and I detest the new format (even if it were to run on my computer)?
    I'd love to be able to access my Xmas playlist someday.

    What didn't work?  Removing everything or just the older version of Bonjour?  Did you follow the instructions in the link I provided above to walk you through the process?
    Perhaps it would be a better idea to post this in the iTunes forums, since it is an issue with iTunes and your iPod Shuffle.

  • TS4123 I have used iTunes for awhile and now on my laptop when I try to open iTunes I get the following message.  "The file iTunes Library.itl cannot be read because it was created by a newer version of iTunes.  Any help or suggestions?

    I am unable to open my iTunes on my Toshiba laptop.  I keep getting an error message of "The file iTunes Library.itl cannot be read because it was created by a newer version of iTunes.  I don't have the problem on my iPhone though.
    Any help or suggestions will be greatly appreciated.
    Thank you

    Unless you've recently attempted to downgrade iTunes this is probably a sign of a corrupt library file. See Empty/corrupt library after upgrade/crash.

  • Firefox won't start, there is no error message and it is not already running.

    Hi,
    When I try to click on firefox, the little wait icon appears and then disappears. Nothing opens, not even safe mode. I've looked at the "Firefox won't start and there is no error message" help section and looked at my task manager processes. It seems that when I click firefox, it briefly appears on my processes and then disappears. This happened yesterday while I was in the middle of using it. At the same time, my Skype also crashed, which makes me think the two are correlated. The two programs still don't work. The only way that I can open firefox is if I install it all over again with the "launch firefox now" option checked at the end. When I have a firefox window open, I can open other firefox windows just fine. When I close it, nothing opens. Thanks for your help.

    1) Start Task Manager
    2) Open Processes (make the description area large enough to see)
    3) look for a description that says ''firefox''
    4) Select it and press End Process
    '''Now Firefox should work properly.'''

  • I keep getting this error message and Firefox won't start....Exc in ev handl: Error: Error setting property on NPObject!

    Firefox won't start and this message keeps coming up....I uninstalled and reinstalled....but didn't help...
    Exc in ev handl: Error: Error setting property on NPObject!

    Disable "McAfee Site Advisor" extension which was just updated to 3.4.0, which probably took it out of the addons block list.
    * "Ctrl+Shift+A" > find McAfee Site Advisor and use "Disable", and then restart Firefox.
    * Do a Google Search no problem
    * It seems that if you re-enable Site Advisor again, and restart Firefox you are okay. At least you know where to look if you get the error again or Google searches slow down.

  • After reboot firefox won't start. runs in task manager, but won't pop up. reset, safe mode and uninstall/re-install won't help. ok if no reboot.

    win7 Pro. has been running firefox ok. but lately with 25 and now 26, the firefox won't start. I can see firefox is running in task manager. but it just won't pop up.
    if I download it again and install it, it will run, but every time I reboot the system, it just won't run again.
    try: reset, safe mode, uninstall & reinstall, new/clean profile, none of those work.

    There may be a corrupted file on Firefox.<br>
    Please attempt to perform a clean reinstall. <sup>[https://support.mozilla.org/en-US/kb/forum-response-clean-reinstall (More Details)]</sup> This is different than a regular uninstall.
    If a clean reinstall does not fix the issue, please try starting your operating system in safe mode.<br>
    To do so, please do the following:
    #Ensure that your computer is shut down completely
    #Press the power button
    #Tap the <code>F8</code> key repeatedly before the Windows logo and startup screen is displayed
    #Select Safe Mode With Networking for the advanced startup options list
    Please report back with the results of both solutions.

  • Firefox update failed, so I re-installed. Now firefox won't start up at all?

    ''locking as a duplicate of https://support.mozilla.org/en-US/questions/969557''
    So I ran firefox, and it was updating. While updating, firefox crashed for no apparent reason so I had to close it. Afterwards, every time I tried to start up firefox, it gave me the update failed error, followed by a crash less than a second later. I followed some instructions, uninstalling and re-installing firefox (without removing personal data), but now firefox won't start up at all!
    Now what?

    We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.
    #Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
    #In that text field, enter %APPDATA% and press Enter. An explorer window should open.
    #From that explorer window, double-click on the ''Mozilla'' folder, then double-click on ''Firefox'' and then on ''Crash reports''. Double-click on ''submitted''.
    #Now, you should see a list of files that contain reports. Go to ''View'' > ''Arrange Icons by'' > ''Modified'' to get the most recent files at the top of the window.
    #Open the most recent 5 files with a text editor and copy the IDs.
    #Paste each ID with '''bp-''' into the reply window on the forums.
    Thanks in advance!
