Update 40.0.2 is slow, hangs a lot, even in safe mode.

So, I tried several things in the troubleshooting here in support articles, but none solved my problems.

Basically, after that automatically put Firefox updated to 40.0.2, the browser crashes a lot on the opening and closing of tabs, loading Web sites as well. When idle, the CPU/RAM usage is normal, but opening or closing of tabs uses a lot of CPU (most of the time, 100% of the CPU is used in navigation) and it crashes every time. Scroll to the bottom of pages also allows the browser to hang. I tried to deactivate several plugins and extensions and I even tried to use the safe mode, but even in safe mode, it happens constantly. I'll post the specs of my computer (no), but don't forget that those issues didn't happen before the update.

Core 2 Duo 2.93 GHz
4 GB OF RAM
Windows 7 Ultimate 32 bit
GeForce 8400GS

Please, what is anyone has found problems with this new update? What should I do? I use Firefox since 2007 and I love it, I wouldn't move to another.

Create a new profile as a test to see if your profile is the source of the problem.

See "create a profile":

If the new profile works then you can transfer files from a profile already used in the new profile, but be careful not to copy files corrupted to avoid transporting more problems.

Start the computer in safe mode Windows with network support (on the startup screen, press F8) to see if it has an impact.

  • Update of FF, message says to restart to complete the previous update. I reboot with the same message. Tried to uninstall. Same message, even in Safe Mode.

    I tried to update Firefox and repeatedly getting this message: "your computer must be restarted to complete a previous update of Firefox. Do you want to restart now? "If I click on no, nothing happens." If I click Yes, it restarts and I get the same message all over again. I tried to uninstall the program and get the same message, even in Safe Mode. I tried to start with a configuration of the previous system, but the computer would not give me the dates of previous configuration. I am running XP, and I deleted Internet Explorer, so I can't access the Internet on this computer. I tried to install the update by downloading the upgrade on another computer and transfer it to a flash drive, but I got the same results. If I go to control panel configuration/Add / Remove Programs, it says I have Firefox Version 13.0.1. For about 6 months before this incident, I get a message when I load Firefox, who said that he could not install an update attempt. If I clicked OK, at least he'd still go the old version. Now, he will do even that.

    Hello, the installation of #3 in the initial response folder is referring to the entire directory "C:\Program Files\Mozilla Firefox", not any subfolder or file in particular. If the directory is still present after uninstalling firefox via the windows control panel, and then if it please delete the whole folder "C:\Program Files\Mozilla Firefox" & try reinstalling firefox afterwards.

  • Window remains white screen after starting windows screen. the system hangs after Mup.sys on safe mode

    The title pretty much everything said.

    The problem occurred on a fault that Dell Vostro 2510 with the additional option should only do the downgrade of Win Xp (from Vista).  As noted, on normal startup, the system will remain in a blank screen after the Windows Xp "loading" screen.  And on safe mode, it will join Mup.sys and then hang there.

    The closest thing that I got from a web search was a thread in forum saying that the official info from Microsoft was that it was a question of Win Xp/motherboard (http://www.hardwareanalysis.com/content/topic/31874/?o=40 halfway to a post by Bobb Fwed).  The poster provided no link, so I don't know how official his info was really.

  • Windows XP hangs at the splash screen, safe mode does not work either

    I've updated my laptop with a windows update and when I went to restart, it crashes just in the start screen.  I tried in safe mode hanging at MUP. SYS and I tried the last known configuration.  So far these options do not work.  I tried Memtest, HDAT2, Ultimate Boot CD tests, chkdsk/p and chkdsk/r, Windows XP, CD recovery and rebuild, tried to start up with each opening of USB port and even tried formatting and installing Windows XP Pro SP2 and Windows XP Home Edition SP1.  So far I have always in step 1, where nothing has solved nothing.

    I noticed that there is a thread here where a person has had the same problem and he said that it has updated its BIOS.  For hours, now I did research on how update my BIOS by creating a bootable disc...  I'm thumbs on a mile it looks. Here is a link to the thread with the person who had the same problem. http://social.answers.Microsoft.com/forums/en-us/XPRepair/thread/2b3f344c-F923-4D84-868d-c0be603e601b

    Well I tried to Win 7 on a bootable disc.  I followed a bunch of instructions I found on youtube.com, but for some reason that I could not burn to disc.  Kept getting an error even if I followed every perfect step.

    In any case, I watched my CMOS on compensation, but the battery is soldered on.  I just messed with it a little bit to see if it was lost or anything thing but I didn't rip out and one other solder on because I have never done this before.  So I put everything back together, turned on my laptop and it finally starts up the Windows installation screen.  FINALLY!  Thanks for everyone's help and patience.  I guess the battery has lost... but not quite sure.  I left the laptop off for about 4-5 days before I tried to play with the CMOS this morning.

    Daavee, thanks for your help on this.  I learned all troubleshooting and making the ISO.  Have a good Christmas!

  • Firefox worked FINE yesterday and it auto-updated and now whenever I load the Web site, it crashes immediately, even in safe mode. Help please?

    I tried the following-
    refreshed Firefox
    uninstalled/reinstalled firefox
    safe mode
    removed the malwarebytes program due to work for someone else
    has ran my spyware, zero results returned

    Chrome works very well. Everything else is fine. Firefox had no problem until it auto update last night. I can't submit a crash report because every time he asks me I say Yes and then he tells me 'problem presentation report '.

    This looks like a problem with the NVIDIA Network Access Manager.

  • As updates of last week that Firefox crashes every time to open google maps even in safe mode

    Last week Firefox updated itself, and there was a java update also. Since then I couldn't access google maps in my browser, whenever I get the gray background and then blocked FF. Have you tried to erase the cookies, safe mode, disabled the few plugins installed and a complete reinstall... same problem.

    Completely fed up with this

    There's a 37.0.2 provided on-demand which should be released in the coming days.
    The Release Notes are already online:

  • Firefox crashes on opening a few seconds. has all of a sudden started several weeks ago and I have not been able to get since. I reinstalled but update did not work. It will not be open even in safe mode. Help!

    Firefox crashes on opening a few seconds. That started everything suddenly a few weeks ago, and despite several attempts to every day, I still cannot load firefox application. It crashes immediately on startup every time anything and journalist accident happens. I studied all the articles and followed their suggestions. I installed the latest version of firefox and still get the same results. I can't even open firefox in safe mode.

    Heather, not sure I can help, I'm not a Mac user, but I'll have a look at the crashIDs that you provided.

    Update:

    There are very few reports recent crash with this signature, they could even be your plant. If you follow the suggestions in the article I linked above there is not much that can be done easily. You should try discount the possibility that the cause is malware by scanning with several updated tools.

    Malware controls
    Have you seen and followed the advice

    Clean reinstall it
    If you find no malware, it can be interesting to try a new re - install and a clean profile, none of them are simple and must be done with care, so first try malware scans, those who will take a while to sort.

    Rather a last resort: fill out a bug report

    If you are ready to try to answer the inevitable questions and have an email account anonymous, that you can use for recording, you can follow the link from the report above and click on 'report' to create a bug report on the crash.

  • I was not able to get on firefox for weeks! It crashes on opening a few seconds. I reinstalled hoping to be updated, but that has not worked. It will not be open even in safe mode. I'm desperate...

    all of a sudden a few weeks ago, I can't have on firefox. It crashes immediately on startup every time anything and journalist accident happens. I studied all the articles and followed their suggestions. I installed the latest version of firefox and still get the same results. I can't even open firefox in safe mode. I don't ' know what else to try and really need my favorite browser back and all my favorites and passwords...

    Since I exhausted all angles throughout January and early February, I can't really identify what makes the difference, but today... IT WORKS NOW! Firefox has been removed from my computer for a few weeks now, so with renewed determination I searched all single folder on my entire hard drive and found 3 random files with mozilla or any part of the word inside mozilla and erased. I turned off the computer and restarted a few hours later. I downloaded firefox 10 (still higher version than the one I was updating of a month) from google chrome and installed it. so thank you for your comments and help!

  • Windows Mobile 8 slow and freezes and cannot enter safe mode

    Hi guys, I hope you can help me with a Windows laptop, 8 that gives me problems. I'm trying to help out a friend, and honestly I feel like I'm out of my depth. The initial problem was that the laptop has been slow to respond, very slow, I suspected a virus, ran a Norton scan, it turned up nothing, I ran out of time so I put in safe mode and it gives back, with a significant improvement of the laptop in safe mode. I got the laptop back today and it is always very slow to respond despite having 6 GB of RAM and specifications that must run Windows 8 very well. Is no longer possible in safe mode, and every time I try to put it in safe mode I see Start followed a white/black screen samsung, i.e. when the process ends. However when I try a normal start it starts, but at a snails pace and goes to the login screen, where it is only partially acceptable (it meets more frequently). Any help you guys can provide would be great, thanks in advance, do not hesitate to ask any questions and I'll try to get back to you as soon as POSSIBLE.

    Hello

    You might want to look in the Startup tab of the the Task Manager for any substance uneeded...

    In particular, all that has changed recently...

    You could also look into the Services of MSCONFIG tab, hide all Microsoft and see what remains...

    Someone not know I had a similar problem, and their main problem is that something called LogMeIn.

    It is in the Startup tab...

  • Facebook, Gmail and MétéoMédia works does not for me with the last update, even in safe mode

    That pretty much sums up it. Since yesterday, with the most recent update, firefox does not display correctly these sites. Someone else posted a question similar to this topic. It has been marked as resolved, but there is no solution posted. Here's his question: https://support.mozilla.org/en-US/questions/963125 I have the same problem as him with fb. In addition to the problem with fb, Gmail doesn't end loading. And MétéoMédia do not display the weather forecast. I'm sure that many other sites are affected as well.

    All sites work properly in Seamonkey, which I use once again, now. I went to oldapps download v. 22 of ff, but whatever the most recent update changed only came when I installed v.22. The problem persists. I could uninstall it completely and then new installation v.22, I guess, but I'm afraid that my browsing history, sessions, passwords, etc., would be affected, and I don't want to find all the files and support first. It's a hassle. Since the sites work in Seamonkey, I'm guessing that's not the fact that I have updated flash at the same time. I don't know how much these sites use flash, either. But if it's a problem of flash, I tell myself I should have the same problem in Seamonkey, and I did not.

    I wish that you guys would have an easy option to restore your updates because it's pretty darn annoying when they cause problems. Usually, they are not lethal problems, however, and the browser still works. Now ff does not work for some sites I use most often.

    Hello

    Many issues of the site can be caused by corrupted cookies or cache. To try to solve these problems, the first step is to clear cookies and cache.
    Note: This will be you temporarily disconnect all sites, you're connected to.
    To clear the cache and cookies to do the following:

    1. Go to Firefox > history > clear recent history or (if no Firefox button is displayed) go to tools > clear recent history.
    2. Under "Time range to clear", select "all".
    3. Now, click the arrow next to details to toggle the active details list.
    4. In the list of details, see the Cache and Cookies and uncheck everything.
    5. Now click the clear now button.

    More information can be found in article to clear your cache, history, and other personal information in Firefox .

    __________________________________________________________________

    Also, some Firefox problems can be solved by performing a clean reinstall. This means that you remove Firefox program files, and then reinstall Firefox. Please follow these steps:

    Note: You can print these steps or consult them in another browser.

    1. Download the latest version of Firefox from http://www.mozilla.org office and save the installer to your computer.
    2. Once the download is complete, close all Firefox Windows (click on quit in the file menu or Firefox).
    3. Remove the Firefox installation folder, which is located in one of these locations, by default:
      • Windows:

        • C:\Program Files\Mozilla Firefox
        • C:\Program Files (x 86) \Mozilla Firefox
      • Mac: Delete Firefox in the Applications folder.
      • Linux: If you have installed Firefox with the distribution-based package manager, you must use the same way to uninstall: see Install Firefox on Linux. If you have downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
    4. Now, go ahead and reinstall Firefox:
      1. Double-click on the downloaded Setup file and go through the steps in the installation wizard.
      2. Once the wizard is completed, click to open Firefox directly after clicking the Finish button.

    This will remove not essential info unless you check the box "delete all my personal data too.

    Please report back to see if this helped you!

    Thank you.

  • Windows does not start in normal mode after the Trend Micro update a few days ago. I can only work in safe mode. Whenever it freezes in normal mode just after typing my password. Help, please.

    Trend Micro update

    If the information below does not help, contact Trend Micro because it is their product that caused the problem:

    http://eSupport.trendmicro.com/default.aspx

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Restore point:

    Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

    Try a restore of the system once, to choose a Restore Point prior to your problem...

    Click Start > programs > Accessories > system tools > system restore > choose another time > next > etc.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

     

    If restore work not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:

    Download the ISO on the link provided and make a record of repair time it starts.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

    When you have changed that, insert the Bootable disk you did in the drive and reboot.

    http://www.bleepingcomputer.com/tutorials/tutorial148.html

    Link above shows what the process looks like and a manual, it load the repair options.

    NeoSmart containing the content of the Windows Vista DVD 'Recovery Centre', as we refer to him. It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC. Technically, we could re-create this installation with downloadable media media freely from Microsoft (namely the Microsoft WAIK, several gigabyte download); but it is pretty darn decent of Microsoft to present Windows users who might not be able to create such a thing on their own.

    Read all the info on the website on how to create and use it.

    http://NeoSmart.net/blog/2008/Windows-Vista-recovery-disc-download/

    ISO Burner: http://www.snapfiles.com/get/active-isoburner.html

    It's a very good Vista startup repair disk.

    You can do a system restart tool, system, etc it restore.

    It is NOT a disc of resettlement.

    And the 32-bit is what normally comes on a computer, unless 64-bit.

    Incident reports could help us by giving you an individual diagnosis, but if they are accidents of almost instantaneous startup, allow me to mention something that is 'flow' where you have this problem:

    Firefox crashes a few seconds of starting if you have either the Applian Technologies Freecorder and Replay Media Catcher programs in combination with Norton Security software (and possibly other security software).

    If you have either of these Applian programs and it is not essential, try to uninstall it then restart Windows to ensure that none of its components are running.

    Firefox will start normally after that?

    (If you do not uninstall the program, another user said he used msconfig to stop execution at startup and that fixed FlvSrvc.exe. See: https://support.mozilla.org/questions/1086722#answer-789197)
