Firefox randomly shuts down, crashes almost every day. 80+ times in the last 6 months

Generally I will have 1 or 2 Firefox windows open with possibly 4 or 5 tabs in each. I may be reading an article, or doing nothing at all, away from computer not touching anything and presto CRASH. This has been a nearly daily occurrence, sometimes multiple times in a day, rarely go 2 days without at least one. There seems to be no common thread to the crashes. I have done all of the updates, tips, etc. that I can find. All "Add-ons" are up to date except that I have tried to update "Adobe Acrobat" several times and, although I go through the process and it says it is done / completed, it still comes up in my "Add-ons manager" as "Outdated Plugins". I've run multiple virus and malware scans, all clean. I'm running Windows Vista.

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!

  • My MacBook Pro gets a gray screen followed by a message that I will have to shut down.  This has happened five times in the last 8 days.

    This started happening around the beginning of this year.  I contacted Apple Support and they worked with me on-line and over the phone.  It happened again the next day.  After it happened about 20 more times, I took it into the Apple Store and they decided to reinstall the OS.  Since then, it has happened about 10 more times. 
    This has happened with and without attached devices or flash drives.  It has happened on different wi-fi networks.  It generally happens when I am navigating with the track pad or with a mouse.  I don't recall ever leaving the room and returning to find the gray screen.  In other words, it happens shortly after I have moved the cursor.  I've noticed the pinwheel usually appears before the gray screen.
    Any suggestions?

    Bad sectors on the hard drive or failing drive, pinwheels usually means there is a delay of some sort from either the network or the storage drive, but not exclusive.
    If you reboot to gray screen, hold the shift key down while rebooting, that may get you back in

  • Iphoto shuts down immediately upon opening.  It goes to the last picture that I was viewing and then errors out.  I get the message that "iPhoto quit unexpectedly" and then get to Ignore, Report, or Reopen.  Nothing has been successful.

    What can I do to correct the problem with iPhoto closing immediately without loosing my photos?

    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
    Step 1
    For this step, the title of the Console window should be All Messages. If it isn't, select
              SYSTEM LOG QUERIES ▹ All Messages
    from the log list on the left. If you don't see that list, select
              View ▹ Show Log List
    from the menu bar at the top of the screen.
    In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter the name of the crashed application or process. For example, if iTunes crashed, you would enter "iTunes" (without the quotes.)
    Each message in the log begins with the date and time when it was entered. Select the messages from the time of the last crash, if any. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
    ☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
    Please don't indiscriminately dump thousands of lines from the log into this discussion.
    Please don't post screenshots of log messages—post the text.
    ☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
    Step 2
    In the Console window, select
              DIAGNOSTIC AND USAGE INFORMATION ▹ User Diagnostic Reports
    (not Diagnostic and Usage Messages) from the log list on the left. There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of crash reports. The name of each report starts with the name of the process, and ends with ".crash". Select the most recent report related to the process in question. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
    I know the report is long, maybe several hundred lines. Please post all of it anyway.
    If you don't see any reports listed, but you know there was a crash, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
    In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
    Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

  • Thinkpad Yoga crashes almost every day

    A few weeks ago my 4-year old laptop started crashing a few times every week, so I decided to get a TPY. I received a 20CD000MMH (I5, 8 Gb RAM, 500Gb HDD+16Gb M.2 SSD) with windows 8.1 Pro (64 bit) on the 20. Feb and since then the longest time it has kept running is less than 48h. I've been downloading both recommended and optional  (12. Feb BIOS update was optional!) Windows and Lenovo's System Updates every day, sometimes twice a day: after a crash System Update usually wants me to reinstall the LAN driver. I've reinstalled Intel's graphics driver several times over as well. For example yesterday screen brigthness was stuck at max after a BSOD, so at least it seems sometimes System Update is right in it's reccomendations.
    Currently I have 5 files in the Windows minidump folder, about as many BSODs did not result in any. I've also done 2 resets after discovering in the morning that the computer is almost too hot to hold and won't shut down. Fortunately those have not recurred since disabling "turn off display" last week and checking every time I go to sleep that the computer really is off.
    I haven't found many posts from other people who have this many crashes - I'm starting to feel I'm missing something obvious or have a really, really bad example of a TPY. At least there are no ghosting issues, although the SSD worked for caching for only a single glorious day of sub 20 sec. boots. Now I'm back to 1min+...    
    Does anyone have any advice, besides returning it? The only thing I think I haven't tried yet is messing with the virtual network adapter (http://forums.lenovo.com/t5/ThinkPad-Edge-S-series/Thinkpad-Yoga-not-waking-up-after-sleep/td-p/1348... as I'm afraid of permanently losing the network connection (which has been working fine) or something and I haven't foud any real instructions.

    And an update about my TPY also: my local Lenovo service couldn't find any hardware or software issues and it did not crash when it was there for two and a half days. They barely used it though. They did suspect the problem might have something to do with Lenovo and Microsoft programs being incompatible (both have power managers, for example) while running simultaneously. We decided to test software issues by having them reinstall Windows (on a 128 Gb M.2 SSD, which I had bought a few days before as I was sick and tired of the barely functional SSD caching) and by me avoiding any and all updates besides antivirus definitions. So far I've had one crash in 3 days, although it was not a BSOD. It just freezed up while watching a video and I had to reset it with a pin. So things have gotten better, especially considering I now can start using the computer in less than 30 seconds instead of 3 minutes after a crash. It's still not good though and there seem to be some memory issues: when I wake up the computer or restart Windows the setting keep changing for no reason. So far the desktop background has changed color, scaling goes from 125% (which I prefer) to either 100% or 150% and the mouse pointer size changes. Also I've gotten some memory errors (displayed too briefly to write down) when making changes to the account that require me to log off. I'll keep it for a few days and look for additional problems but it looks like I'm going to have to have the motherboard replaced...

  • Firefox always shuts down/crashes when I am trying to print something. Why is this and how do I fix it? Went back to old version so I can print things, btw it is all printing in any website including emails.

    Does not matter what website, email or pop-up and try to print something. After you click okay on the print pop-up window it shuts down. The old version does not do that, so this tells me it is Version 4 that is the problem.

    You can use the NoSquint extension to set font size (text/page zoom) and text color on web pages.

  • FF has been crashing almost every day, and usually i can restore it but today, all my links are GONE! what do i do? I have version 3.6.6 none of your suggestions helped.

    i am running 3.6.6 version. FF has been crashing almost daily for the past week. i have 3 tabs open on it most of the time. i usually use Google Chrome for most of the tabs/sites i use during the day. i only use FF for a game and the local radio station, sometimes 1 other tab. i had a lot of personal links in the bookmark section--taxes, music, ministries, medical and state assistance info. they were there this morning after a crash/restore, but when i got in this afternoon, the bookmarks were all gone.

    1. The message you got about the Library needing to be upgraded was bogus. There has been no new version of iPhoto 11 that runs on 10.8 in more than a year. You got that message because your Library was damaged. So, nothing to do with Apple's updates - none have applied to you for a few years anyway.
    2. Do you have a back up of your Library? The most simple way forward right now id to restore from it.
    3. If you don't - and you really should change that policy right now -  then
    Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
    This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
    Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

  • My macbook pro 15 mid2010, crash every time in the last month. What can i do? Is a hardware or software problem?

    The problem is that my mac is working very well, in soft programs, like browser or text editing, and then stop. Stop for one eternity, until i do a hard shut down.
    After this situation apper´s many times, in a single day, i went to a apple service store and left my mac to repair. At first, the tecnhical manager told me that happens a lot, and the problem are in the logic board. Well, when i pick up the mac, he told me that was a software problem and was solved with the instalation of 10.8.5, but in that same day, he crash 3 or 4 times, in different way´s. Now, he crash´s and restart alone, and at the first try don´t restart appearing one message on the grey screen.
    I don´t know what is this problem.
    Someone have or had this problem too?
    What is the solution?
    Thanks a lot...

    Maybe find a local who can translate for you. I don't know what to tell you for dealing in another country for service on your computer.
    I can offer you something you can do if you want to give it a try. You'll need a backup of your data in your Home folder because you need to erase the drive. You'll also need a solid, preferably fast, internet connection.
    Install or Reinstall Lion/Mountain Lion from Scratch
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Erase the hard drive:
      1. Select Disk Utility from the main menu and click on the Continue button.
      2. After DU loads select your startup volume (usually Macintosh HD) from the
          left side list. Click on the Erase tab in the DU main window.
      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
            the Security button and set the Zero Data option to one-pass. Click on
          the Erase button and wait until the process has completed.
      4. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.

  • I have updated Adobe flash plug-in but it continues to crash. It has crashed on me over 3 times in the last hour; why is that? Is it firefox?

    I have updated Adobe flash plug-in more than once, but it continues to crash. It always does it right in the middle of a game or something I'm playing. Now, I pay real money to play these games so that I can purchase certain things, so this is now frustrating me. If it's firefox that keeps adobe crashing please let me know so that I can go back to using internet explorer.'''bold text'''

    James j,
    You have a different problem. Your screenshot shows "The Adobe Flash plugin has crashed".

  • Downloaded version 10, when I log on it wants to restart all the time. It has shut down and restarted at least 10 times and the same message still comes up "Your system has to be rebooted." and when you do the same message comes up?

    Cannot logon to Firefox now that version 10 has been installed. I cannot even delete the program from my system. To delete it gives the same message "Your system has to be rebooted" What is going on?

    Hi Cot230tage,
    Usually the only reason it will ask you to reboot is if there is a file that must be modified that the updater doesn't currently have access to. You should try running the Firefox program once as Administrator:
    * Right-click the icon and choose ''Run as Administrator''
    If that doesn't help then do a clean reinstall.
    # Download a fresh copy of Firefox from the [http://www.mozilla.org/firefox/fx/ Mozilla download page] and save the file to the desktop.
    # [[Uninstalling Firefox|Uninstall]] your current version of Firefox and remove the Firefox program folder before running the new installer.
    # Run installer
    Remember that you don't want to remove personal data when uninstalling. That way you'll still have your personal information.
    Hopefully this helps!

  • IMac Randomly Shuts Down -Overheating Problem?

    I've posted in these forums once before about my iMac randomly shutting down. I believed I had solved the problem by following another users instructions which were as follows:
    "Machines that are just randomly shutting down are usually caused by defective hardware. The only thing that can be done about that is to call Apple and have it replaced or serviced. There is probably not any one particular solution as it could be any number of the internal components failing and the resulting symptoms could be the same.
    If you'd like to do some hardware tests yourself before calling Apple that can be done. First try resetting the SMC: http://docs.info.apple.com/article.html?artnum=303446
    Next insert the original gray install disk, restart your iMac, then hold down the "d" key until it boots up into the Apple Hardware Test. Run the extended test.
    Also if you have Apple Care install TechTool Deluxe from the cd provided. Then run TechTool on your system."
    I also removed and replaced of a defective external HD that I thought my be causing problems. But after all these steps, the machine kept turning itself off.
    I had read in some forums that it was due to the internal temperature of the iMac. So I downloaded smcfancontrol 2.1 and increased the fan speed on the internal fans. This did bring down the temperature as revealed by the iStat Pro widget. However, I still had another shutdown.
    So I turned off the machine, went to bed, and this morning when I turned it on iStat Pro said these were the internal temperatures of the iMac:
    CPU A 77 degrees F
    GPU 85
    GPU Diode 88
    GPU Heatsink 85
    Ambient 61
    Memory Cont. 74
    Airport Card 112
    HD Bay 1 76
    I find these numbers to be unbelievable. Especially the airport card. When the whole system seemed to be running hot, the Airport Card said it was 122. It always says something above 100 degrees. The other temperatures also seem out of whack. How can the CPU be 77 degrees after 10 hours of being completely powered down in an office environment that is only 55 degrees?
    Has anyone else run into a similar problem?
    Has anyone else found the problem to be a faulty temperature sensor (and is there a way to reset it, or does it have to be replaced)?
    Overheated? in Oregon...

    Certainly sounds like a case of the left hand not knowing from the right, huh
    Well, I have my call in, and I am getting onsite service to replace the logic board, as per Apple's recommendation.
    I'm reading the other longer thread (171 replies), and it's disheartening to hear how some of the "geniuses" are handling this problem. They can't replicate it by leaving the mac running overnight, so "the problem doesn't exist". Hello! It's *random*! As in, not easy to replicate!
    I'm also a bit disillusioned that the popular Mac sites (TUAW, etc) haven't picked up on this story yet. I emailed TUAW the link to the long thread, and they ignore it. Usually when this gets more "mainstream" press, then Apple finally steps up, acknowledges a problem, and serious fixes are made. Right now, it's a bunch of complainers (me included) in some threads on the Apple site.
    I took a huge leap last November, and went from PCs to the Mac platform, after working on my personal migration plans for a month prior - how to move from my photo editing on the PC to the Mac (I wasn't about to buy another full copy of Photoshop, for eg, but I did find out I could upgrade from Win PS to Mac PS), if all the programs I use for photography and design were available on the Mac, learning the ins and outs of shortcut keys, how things are done, etc etc, and was so happy initially when I got the Mac and said goodbye to the PC.
    Now I'm literally afraid to do any serious work on the Mac for fear of the "pulled plug" syndrome losing the last 20, 30 minutes of work I've been doing because I didn't save every 2 minutes. And iLife's Pages doesn't autosave (much to my chagrin), so I've lost some long correspondence and articles typed because I didn't save it before the pulled plug o' death.
    Not a very nice computing experience.
    As a suggestion, maybe everyone reading this and the other thread can flood TUAW.com with a news suggestion to cover this problem. Engadget, Gizmodo too while you're at it. I think once these million-viewers a day blogs cover it, we'll see some real action from Apple.
    Just a thought....

  • T410 randomly shutting down

    I've had plenty of issues with the T410 already. Got a key stuck error which forced support to change the main board AND keyboard.
    Shortly after that the computer started randomly shutting down. Wether on power cord or battery the PC just suddenly dies. in a split second disk and fan stop spinning, screen goes black, so do all lights. Only the green light by the FPR lights up. 
    Now nothing makes the computer boot. Not pressing the power button or sweeping my finger (which does turn the green light off). 
    In order to bring the foul thing back to life I need to unplug the power cable, remove the battery and only then does it respond to pressing the power button. Main problem is that it is now off warranty, and even if it was under warranty, I'm not willing to drop the thing on the depot for 60 days like last time around. 
    So, here goes a long shot hoping that someone has a magic bullet to solve this. 
    OS: windows 7 pro, 64 bit
    type: 2516-cto

    Blown capacitors on the motherboard can sometimes cause a problem like this allow they usually make the machine shut down much quicker than 4 hours..If you open the machine you will the tops of the capicitors bulging if this is the problem.

    Our early 2006 Intel Imac has recently started to switch off at random times. There doesn't seem to be any particular point at which it will do this and no warning either. It's as if somebody has pulled the plug out but the power supply has not been touched! It then often won't allow you to switch it on again until you have left it over night - or sometimes it will switch on after a few minutes.
    It is very frustrating as you never know when it might happen, it has been ok for a couple of weeks but now it has done it twice in the last two days.
    We did take it to the Apple Store, who said they had kept it on for a day and could not replicate the issue so therefore there is nothing they can do...
    If anybody can shed any light on this mystery it would be VERY much appreciated.
    Thank you!

    Hello and welcome to the club of "random shut down".
    Since 8 days I am also having this problem on an early 2006 2 GHz intel core duo with OS 10.4.11 After approx. 5-10 minutes it shuts down and the only way to wake up again is to disconnect the plug, wait 10 sec and connect it again and push the start button on the back.
    There a many discussions ongoing and also many suggestions (SMC reset, memory replacement, change the power cord etc.). Nothing really worked in my situation. My assumption is something with overheating, but the widget "istatpro" or "tempmonitor" are showing not more than 35°C on the CPU at a max.
    I found a little tool called "smcFanControl" to adjust the minimum speed of the fans (my settings: ODD 2850 rpm, HDD 3150 and the CPU fan at 2160 rpm) and since that adjustment the working period seems to be much longer. Sure, there is an annoying noise now, but I can use the imac again.
    Hope that there will be a better solution soon.

  • IMac seems to randomly shut down

    This is very strange...my 2.0GHz iMac G5 (May 2005) appears to be randomly shutting down. I don't know much about the problem because it usually happens during the day when I am at school. I checked the Power Saver settings and I have it to never sleep, never shut down, etc.
    Any other possible causes for this problem? It's minor but frustrating. Thanks!

    Actually....I read the article a little more thoroughly....
    "The program is available for certain first generation iMac G5 models that were sold between approximately September 2004 and June 2005 featuring 17- and 20-inch displays with 1.6GHz and 1.8GHz G5 processors.
    The affected iMac G5 computers have serial numbers where the first 5 digits fall into the ranges noted below.
    Serial Number ranges:
    W8435xxxxxx - W8522xxxxxx
    QP435xxxxxx - QP522xxxxxx
    CK435xxxxxx - CK522xxxxxx
    YD435xxxxxx - YD522xxxxxx
    Some second generation iMac G5 computers have serial numbers that fall within the upper band of the ranges listed below. Only first generation iMac G5 computers are affected by this program."
    It seems my iMac is a second generation. Luckily, it's still under the one-year warranty. I'll have to look into this.
