Firefox is using large amounts of CPU time and disk access, and I need to know how to shut down most of this so I can actually use the browser.

Firefox is a very busy piece of software. It's using large amounts of CPU time and disk access. It puts my usage at low priority, so I have to wait for some time to be able to use my pointer or keyboard. I don't know what it uses all that CPU and disk access time for, but it's of no use to me. It often takes off with massive use of resources when I'm not doing anything, and I may not have use of my pointer for several minutes. How can I shut down most of this so I can use the browser to get my work done. I just want to use the web site access part of the software, and drop all the extra. I don't want Firefox to be able to recover after a crash. I just want to browse with a minimum of interference from Firefox. I would think that this is the most commonly asked question.

Firefox consumes a lot of CPU resources

    I am legally blonde and not very tech savvy, so I don't really know how to do that.  I know ur time is valuable, so could u possibly give me a short tutorial?  I would b very grateful! I use the camera kit to get my pics from my sd card to my iPad and also from my iPhone to my iPad. Had I known I would have this problem, I would not have transferred my pics to my iPad until after I took the sd card and had my pics printed.

    The only option you have is to buy a newer phone. The iPhone 3G can not run anything higher than 4.2.1. It was discontinued years ago.

  • Firefox.exe* uses large amount of cpu 40-50%

    My computer slows and task manager shows firefox.exe* very large cpu usage.

    You can try to disable OMTC and leave hardware acceleration in Firefox enabled.
    *<b>about:config</b> page: layers.offmainthreadcomposition.enabled = false
    You can open the <b>about:config</b> page via the location/address bar.
    You can accept the warning and click "I'll be careful" to continue.
    *http://kb.mozillazine.org/about:config
    Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
    *Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
    *Do NOT click the Reset button on the Safe Mode start window

  • MSMPENG Requiring large amounts of CPU Time

                     <---Time
    This is a picture of the CPU consumption on a multiprocessor cpu activity monitor on Win 7 SP1 running a Sandybridge Extreme. I know there was a problem during XP days. This has been going on for about an hour and one half. The system logical disk is about
    125 GB and I had nothing running at the time. The activity shown was MSMPENG.EXE according to the task manager.
    I am using Windows Defender and Malware Bytes as AV. I've been advised that it's ok to run them both. All disks on the system are SSDs. It's continuing in this state...... The green horizontal line is physical memory consumption which rather low.

  • My email used for my apple id was hacked and I had to give it up. How do I change my primary id? I can't use the one I had that was hacked.

    I have tried to update my id and I seem to be getting a second account because when I enter my current email, apple tells me that I already have an account. I also am told that emails for verification are sent to my hacked account that I cannot access so I cannot get my ipad mini registered. I feel like I have been going around in circles and am very frustrated.

    itune release : 12.0.1.26
    Antivirus software : Kaspersky internet security 2015     release: 15.01.415 (b)
    After iTunes closing the syncserver.exe process will take a large amount of CPU Process.
    The problem has begins after KIS 2015 installation.
    I tried to apply a procedure finded on another forum : Windows 7 compatibility mode and run as administrator for distnoted.exe and syncserver.exe. The problem remaind.
    Thank for your help

    Hello~ Chrisrob94
    My computer environment is
    OS: Win 8.1 x64
    Itunes: 12.0.1.26
    Anti-Virus: KIS2015 15.00.463(b)
    I has same your problem too. But I solved in the following way;
    File Path1:  C:\Program Files (x86)\Common Files\Apple\Apple Application Support\distnoted.exe
    File Path2:  C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\SyncServer.exe
    this file [Right Click] and Properties. on the compatibility tab(click change setting for all users);;;
    then check run this program in compatibility mode for: and select windows 7.
    also check run this program as an administrator. click apply then ok
    if already running syncserver, disnoted kill it. using windows task manager.
    This seemed to fix the problem for me....Good luck to you!

  • Causes windows 7 desktop window manager (wdm.exe) to use large amounts of memory

    Whenever I have Firefox4 open, it causes dwm.exe (Windows desktop manager) to use large amounts of RAM - It starts at about 100MB, quickly increasing to about 1GB over 20 seconds, then dropping back down to 100MB and so on. It does this continuously while Firefox4 is open, with the occasional "Your computer is running slow" message being shown by Windows.
    Update: Only occurs when browser isn't on the primary display on a multi-monitor setup.

    I had the exact same problem. DWM would use massive amount of memory when Firefox 4 was open on my secondary display, especially when scrolling with the mouse wheel. It would use so much that Windows 7 (8GB RAM) would turn off Aero. Going into Options>Advanced>General and unchecking "use hardware acceleration" fixed the issue. Of course now I can't take advantage of any hardware acceleration.

    I Have the same problem, I switched off location services, maps in data, whatever else maps could be involved in nd then just last nite it chewed 100mb... I'm also on vodacom so I'm seeing a pattern here somehow. Siri was switched on however so I switched it off now nd will see what happens. but I'm gonna go into both apple and vodacom this afternoon because this must be sorted out its a serious issue we have on our hands and some uproar needs to be made against those responsible!

  • If I have more then a few tabs open such as gmail, facebook, and a zynga game no tabs will load at all. I close and reopen firefox numorous (Im talking 7 or 8 times or many more) and shut down the zynga game and still it wont load

    If I have more then a few tabs open such as gmail, facebook, and a zynga game no tabs will load at all. I close and reopen firefox numorous (Im talking 7 or 8 times or many more) and shut down the zynga game and still it wont load the tabs or if it does and I then try to add the game or any other site at all on a tab it causes firefox to stop working (though not close) and I have to restart opening and closing it many times to get it to work at all.

    1st, you will not be able to activate your PPro1.5 on ANY new computer, see next link for the special version you MUST use
    CS2 (and earlier) Activation Server http://helpx.adobe.com/x-productkb/policy-pricing/creative-suite-2-activation-end-life.htm l
    2nd, you already mentioned Virtual XP, so if a direct install doesn't work, that would be the way to go... or, to just do what SHOULD work from the start, just do Virtual XP

  • Every time a new window in safari opens, it takes about 2 minutes before I can actually use it.  Can anyone help?

    Every time a new safari window opens, it takes several minutes before I can actually use it.  This seems to have started after the most recent updates.  I have reloaded the operating system, but the problem persists.  Ideas?

    Found the problem  Plug-ins (extensions?)  I had loaded were not compatable with latest update.  Once they were deleted, sfari runs fine.  Hope this helps others
