Why firefox uses so much memory?

For several months, Firefox has eaten memory like crazy. Once I get more than 5 tabs open or that you have Firefox running for more than an hour, the memory usage hit about a GB. If I continue to let go beyond that, it will hit 1.5 to 2 GB and it made my gel set office. I got to keep the Task Manager and every hour or so just kill Firefox and restart. Preventing it from crashing my whole desktop computer. It's definitely worse when I opened Google products, especially maps and Docs. GMail is generally OK.

I tried to disable literally every add-on and Extension (including Flash and Adblock).

I'm on Windows 7, I have 4 GB of RAM installed. I am on version 40.0 Firefox, but this has happened through a few updates now (I think the problem started around March or April). I also tried to back - rev Firefox and go to the latest version, that I had before the problems started, but that did nothing either.

Chrome works fine on this machine without any similar problems - but I prefer Firefox!

  • To find out why firefox uses as much memory, I added the addons-memory, but no where can I find how to run the add-on!

    I can see it in the list of Add-ons, but how can I run?

    He did not appear in the list customize. I reinstalled, and it still does not appear. However, I found on another site this statement, which worked: type about: addons-memory in the address of a new tab bar and it runs. Thank you for your response.

  • Why Firefox uses 496 MB memory?

    According to my virus protection, AVG, I routinely used some memory when I use Firefox. Is this true and if so, can I reduce the memory usage?

    Your comments?

  • AVG says using too much memory because multiple firefox is open, but I only see one.

    AVG regularly analyzes in the background. Lately he has demonstrated a popup window that says multiple applications of Firefox are running and using too much memory, so I should close some. But I can only see 1. Tried CTRL ALT DEL to see if I could find the answer, but only showed 1 firefox, and that he used more than 28 000. So I think that AVG is correct, but does not know how to see what who or where they are. They DO NOT display in the lower menu on the main screen, so I guess they are in the background. Do not have the virus, and Firefox, regularly updates itself. What should I do to fix?

    Hi cmich80220.
    It is true, that you should only be able to run only one instance of Firefox at the same time. I searched but could not find someone else with a similar problem. If the problem comes back to Firefox running slowly, you can consult this article for troubleshooting:

    Hope that helps.

  • Explorer.exe and svchost.exe using too much memory

    I have disabled the automatic updates after the last round of updates, and now, all of a sudden, explorer.exe and svchost.exe use too much memory... enough to interfere with other programs, I try to use.

    Help?

    Windows XP Professional - Svc Pack 3 processor: Intel (r) Pentium (r) D CPU 2.80GHz CPU speed: 2.73 GHz memory: 512 MB

    Why you turn off automatic updates?

    There are between the two options. I just set it to notify. When it is practical, I go to the Microsoft Update slte and use the custom (not Express) option. This gives the user full control of the update of trial.

    You will have a better idea of the cause of the problem using Process Explorer.

    Download Process Explorer.
    For more information about Process Explorer, see here:
    http://www.Microsoft.com/technet/sysinternals/SystemInformation/ProcessExplorer.mspx

    With svchost.exe provide us a list of services using the process. There are number of processes that are using svchost.exe, so we need to know that we provide more targeted assistance. Right click on the process, click on properties and look at the Services tab.

    Solution Explorer. exe has a number of subprocesses. Select the sub-process, click Properties and check the Services tab.

    Have you recently changed all types of starting any service. This often leads to the problem. Users often disable a reflection of service to speed up the system performance. In practice what is done is of one or several programs to malfunction.

    Hope this helps, Gerry Cornell

    Hello

    I inadvertly solves the problem by changing my default from iTunes media player to Media Player.

    Hope this helps someone else!

    Thanks for the link to Process Explorer :)

  • Firefox uses too much RAM

    After the update to Firefox 23 I had a lot of problems. The major problem I had is that Firefox uses up to the amount of memory RAM (from 2 GB for less than 5 tabs assets/load) and ends up crashing. After a few tests, I found that when I closed the tabs that about 2 to 3% of what Firefox started using when I opened the tab is unloaded. Using the about command: memory, I discovered that xpcom uses the more this 1 GB RAM passes after awhile of navigation.

    a user here reported ghostery as a source for leaking memory - you can keep this option disabled for a while and watch the use of resources...

  • I can't watch Flash videos because Firefox uses too much CPU.

    Firefox has become untenable because it uses too much CPU and disrupts the Flash videos.

    I tried to disable or change the values of the plugins. Install older versions. Nothing helps. It just sucks. Makes me want to get out the lungs of someone.

  • Why Firefox uses 100% CPU when I am connected to eBay?

    Firefox uses 100% CPU when I connect eBay.

    Hi apdubois, it is useful to know that Flash is the problem but, as you point out, life without Flash is not very interactive.

    It is a standard orientation that addresses the most common reasons for problems of Flash in Firefox. I'm sure you've seen some of it before, but just in case:

    (1) make sure that all recorders/downloaders who interact with Flash media are as up-to-date as possible, or disable them temporarily.

    (2) disable graphics hardware acceleration in Firefox and Flash

    (A) in Firefox, uncheck the box here and restart:

    the button Firefox orange (or the Tools menu) > Options > advanced > General > "use hardware acceleration when available.

    (B) in Flash, see this article from Adobe technical support: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues

    (3) turn off protected mode (Windows Vista/7/8)

  • VI by using too much memory

    Hi all

    I am trying to write a code for pic Pic 2 dimensional on a large enough data file (about 1000 x 72000 points). The results of this should be integer values where each peak has been reduced to its maximum point for later statistical analysis (see attached code). The problem is when this code is executed, the VI quickly eat through all of the available memory and crashes. I'm under a system with 3 processors and 4 GB of ram, and the program has crashed every time after using approximately 3.5 GB, so I need to find a way to reduce the use of the memory of this VI. My VI and an example of data file is attached. Thank you.

    <><>

    First of all, read 1000x72000x8bytes = ~ 600 MB for one copy in memory is pushing it. Then you have additional copies in the two graphs.

    All your values seem to be small integers, so a U8 2D table would work just as well using 8 times less memory space.

    Then you send these massive arrays of two graphs of intensity. The number of pixels in your chart is a small part of the picture, so you will have to reduce the data to display. Graphical representation of the 72000 columns on a less than 1000 pixels wide screen is ridiculous.

  • Firefox using too much processor power and memory after that I have closed it

    I always clicked on 'X', the red top right of firefox to close. Lately when I do it, my CPU/RAM usage goes up dramatically and ff never really closed, slowing down my whole computer. It's really annoying, and the only way I know to stop it is to complete the process on ff with windows Task Manager. Any suggestions as to what could be the problem?

    If we consider the problem is resolved you can mark it as you please.

    However note that Norton Internet Security, by default, is likely to run 'pulse updates' not really a topic to discuss here, except to say that this activity may well continue, depending on your settings with Norton, regardless of whether or not you have the toolbar installed Norton.

    I currently have a paid for version of Norton installed.

    My understanding is that Norton bar refers to the password management etc for safe research and general connection with the site of Norton.

    • The Norton Toolbar is not compatible with the current beta of firefox 4
    • I don't know if there are other harmful effects on firefox
    • In itself remove the toolbar will not stop Norton software affecting the use of firefox (but this is of course to ensure the safety, I do not pretend you remove, only that you take into account its CPU cost wise)
  • Why system32\svchost.exe using too much memory

    My computer freezes several times a day.  I have to wait several minutes to get it working again.  When it starts up, it shows a window saying c:\windows\system32\svchost.exe uses a lot of memory.  What is the cause for this?

    Hi Cyndy62,

    1. When did you start to question?

    2 did you a recent software or changes to the material on the computer?

    3. This occurs when you use a specific application or all applications?

    Step 1:

    You can check in safe mode and check if it uses the same energy...

    Start your computer in safe mode

    Step 2:

    If you are not faced with the question in safe mode, then you can try to perform a clean boot and see if it helps.

    A clean boot to check if startup item or services to third-party application is causing this issue.

    You can read the following article to put the computer in a clean boot:

    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

    After the troubleshooting steps, please refer to clean the boot link to put the computer to normal startup mode.
