Firefox consumes too much RAM, caused by js

I have problems with Firefox consumes too much memory RAM. Many people are complaining about this, but I have done some additional research before posting here, using the about command: memory and I discovered that js-no-window and js-main-runtime are the cause.

When I start an empty Firefox session I immediately an allowance of 260 MB of RAM. About 75-80% this is taken up by these two processes of js (javascript?).

After opening about 10 tabs with different Web pages, the use of the RAM went up to about 750 MB. During the time that the tabs are open most of the extra of the MB are consumed by the window objects (40 MB per page, yet much seems to just a news with an article site...) but after their closing will not use of memory to the bottom and he transferred to the two already mentioned js process. This transfer to the js process is not always the case, it seems to happen if I open a lot of tabs, let's say 10 + maybe.

I tried to disable Javascript using the SettingSanity plugin, but makes navigation difficult at home of course and the worst of all this does not solve the problem. Specified processes continue to use the same amount of RAM.

I have this same problem on all my computers and laptops, so it can't be a coincidence. Is there anything I can do about it? It is being investigated? How a browser with 10 open web pages may need almost 800 MB of RAM?

And please don't reply not to "install more RAM". The pc with the fact that I have more problems has 2 GB of physical RAM and I really don't think it is possible on a computer of this logon type 10 web pages. Do the same thing in Internet Explorer consumes less than half the amount of memory RAM.

PS: I sent this request using IE because I could ' t access this page in Firefox. The button 'Ask the question' did not work...

I have 2 GB Ram too and can open up to 20-30 tabs before slowing down. Maybe it could be an addon like Adblock more which can cause the memory leak.

Also in this article is to disable hardware acceleration, which can reduce the CPU and RAM use on some systems (if it doesn't, turn it back on).

  • 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.

    Say hello to new parthcool.

    It is a normal behavior of a browser like Chrome or Firefox.  You run several tabs in Chrome?  Chrome treats each tab as a separate instance of the browser and for this purpose a separate process.  It is a good feature because it means that a hanging web page will not (usually) bring down the browser everything.  However, this means that Chrome uses a lot of RAM.

    Using intensive plugins memory within these tabs, like Adobe Flash, will greatly increase the amount of memory used.

    Here is a screencap of my own memory used within Chrome.  I did open Chrome before that and I currently have seven tabs.  This represents about 400 MB with pages containing the text for most.

    Unfortunately, because this is a consequence of the features of the browser itself, there are only a few options to solve the problem.  You can try to minimize the amount of memory that Chrome uses by following the instructions in this article.

    Your second option is to upgrade your laptop to include more memory.  You also extend the usefulness of your laptop.  If you want to go this route, I need your product number to locate the appropriate parts and information.  Follow this document to locate the product number.

    Finally, and this is probably the most effective solution, is to use the Ready Boost of the window function.  Ready Boost allows you to use Flash memory, such as a USB key, as secondary memory for your computer.  Here's a great thread in which explains how to use Ready Boost.

    I hope you find this useful parthcool; have a great day!

    None of this seems unusual.

    MsMpEng.exe is Microsoft Security Essentials.

    Svchost.exe (netsvcs) hosts Windows Update. The memory usage goes up to approximately 1 MB if possible during the verification of the update or install updates the definitions of MSE.

    A vacation message memory when there is available RAM is caused by the paging file is too small. Windows ensures that it is able to provide virtual memory that programs have asked even if they don't have not used them. If the allocated memory was greater than the amount of RAM and paging file space, Windows starts to reject requests for memory allocation.

  • Svchost.exe file LocalSystemNetworkRestricted using too much RAM

    The file svchost.exe (LocalSystemNetworkRestricted) uses too much RAM, almost 1/2 of it.  There are also several svchost.exe files (no limit) and the indexer uses a lot of RAM too. I have already associated the indexer return. I suspect that it is the cause of my favorite right-click with windows Explorer.  I have 4 GB of RAM, small basic programs, file clean constantly and the computer is still slow.  How can I fix it?  Test/scan etc. ?  HELP.............................

  • Firefox takes too much HDD

    Hi, I have installed portable firefox 23.0.1 to q: partition and the partition of 1 GB. Firefox takes 653 MB of available space and it's too much for me, someone knows how to "clean" firefox so my drive is no longer incomplete? I think that firefox should be 70 MB and not 700.

    Hello, yes you are right - it's unusual, portable firefox versions should be more in the order of 70MB. You can use a tool like www.jgoodies.com/freeware/jdiskreport/ to inspect what is too exactly the place and report it here in the forum? Thank you

    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.

    Thank you

    Normal.

    Many applications call the system and ask:

    -"Hey, mate, let me come in.

    If the system has enough memory, it responds:

    -"OK, but don't take too much place.

    If the system is out of memory, he responds:

    -"Rest in peace, friend and let others do the work.

  • The new firefox uses a lot too much RAM compared to Chrome or Internet Explorer.

    Before an administrator reacts, please read, because I noticed that many times on this topic in other threads, the admins will respond as the caricature of the characters, not really listen to what people say.
    I have no extensions or add-ons - Firefox (latest version), Chrome (latest version) and Internet Explorer. When I have a blank page open, and 52 M of RAM uses only a single page, Chrome, IE uses 47 M, and Firefox uses 153 M. It's a freshly reinstalled copy, I have no preference at all, no, bookmarks nothing. Can someone explain why Firefox is forced to use three times more memory than its two competitors?

    The problem was that number of tabs was directly proportional to the RAM (1 page ~ 120M, 2 p ~ 240M, etc.). I have a fast computer, but was limited to three legs, and then everything became marshy. In fact, I discovered what it was. A Flash video extension downloader was inappropriate for the JAVA plug-in applications. I have no idea why this was happening, as the GUI for flash video downloader doesn't have Java, and the site that I was downloading is a medical site that uses flash as a protocol of Embedment for their video playback. Anyway, weird, but resolved. If all appears to be a random problem with the new version of FF, it can be flash-video downloader. A rather random shit page (homepage of Yahoo) is now only have access to 72 M of RAM, a reasonable person are all things considered.
    And forgive my aggression. I frequently don't forget that everything is life and death.

  • 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)
  • Too much RAM

    My computer to windows 7 Home Premium 64-bit use about 50% of RAM when idle with nothing open. This is not good. I got about 16 accidents last month. Finally, they stopped for 2 weeks. But now, there is a problem with my RAM. In addition, my computer will not sleep even though she is set to do 20 minutes. I am sure that my RAM is the thing that is the cause. Browsers open and other information could not fit into the RAM and it is what causes a crash. But the problem is no accident. My RAM is. For your information, I have 6 gigabytes of DDR3 system memory.  And please don't say I have to buy new RAM because this computer is only 4 years old. Even my windows laptop computer x works almost perfectly for 10 years.

    Run: Memtest86 +.

    It runs from a floppy disk or CD and should eliminate or confirm if one or more of your memory

    sticks are bad or the values of the SPD in the BIOS are correct.

    Let it run for as long as you can: 2,4,6,8 or several hours (at least 3 full passes), if no errors at that time then your ram is OK.

  • VDisk consuming too much disk space

    I am running the latest beta with Win7 64 bit for host and client.

    In the client, my main drive looks like this size:

    client_disk_size.JPG

    If you do the math (99, 9-56, 2 = 43.7), my virtual disk should consume ~ 44 GB of disk space. However, it is more close to 83GB (and growing).

    size_on_host.JPG

    When I try to clean the drive, I get a message that the disc is used 79.8 GB and can not be cleaned everything again.

    So, I used the compact function, and after 30 minutes ended, he doesn't drive OVER 4 GB, small.

    It is a problem for me because I have little disk space on my fastest drive where I keep the customer files for obvious reasons. Help please?


    Did a little more digging. Apparently, this update from McAfee that you see last week, 19, included a feature to encrypt my hard drive. I don't know why this would have caused a problem today (and not in the last week), but I wonder whether a hard drive that is encrypted in the virtual machine, which means my entire 100 GB should get distributed.
