• Flash uses a lot of CPU

  I don't know when this started, but recently whenever I visit Web sites that use some or a lot of Flash, Firefox slows down completely. When I went in my task manager, I saw that FlashPlayerPlugin.exe was using a lot of CPU (109, 396 k to be exact). Actually, there are two open process. In the past I've never seen these before in Task Manager, but now it is a problem. Any ideas?

  Nevermind, I found a solution. It seems that there is a new feature implemented by Flash called Protected Mode. To disable it, you must go to C:\WINDOWS\Macromed\Flash then open a text called mms.cfg file and add the following text: ProtectedMode = 0. To disable.

• What is superfetch? Its in my sTask window manager and he uses a lot of CPU power... .do I need it and what is?

  The program is placed in my Windows Task Manager and takes a lot of CPU power, and I wonder what use it perhaps can cause? my CPU usage was 100% and my antivirus uses only 5%.

  "Superfetch" and "The host Windows Services" take so much CPU power on i3, 3 gb Sony Vaio!

  SuperFetch is a Windows service that is designed to accelerate the launch of the app by preloading some applications based on your usage patterns. Tune-up blog has a good explanation of what it does.

  However, it should not be maxing out your CPU all the time. If it slows down your computer, you can try to disable it.

  To turn off:
  Open the Start Menu.
  Type "services" and press ENTER.
  SuperFetch. search in the list and right click > properties
  Set the startup type to disabled, and then click the Stop button to stop the service
  Click Ok

  You want to make sure that your antivirus software is up to date and your computer is clean.

• 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.

• Exec.vi "Wait until completion" system uses a lot of CPU. Help

  I am writing an application that calls parallel instances of an external program. I have the code of work to run the EXE file with the Exec.vi system. When the completion up to wait entry is set to true on Exec.vi LabVIEW system uses all my CPU. The EXE I am running is an exe of low intensity, and if I don't wait until completion LabVIEW has no high CPU usage. It would be nice, but I have the code which needs the EXE to finish before moving. I'm doing something wrong? I could not find this behavior as a known issue, so I would like a mental health to make sure I'm not stupid fouls. I have attached a demo that recreates the question. The VI called the EXE with lance Notepad and then updates the text in Notepad. I am attaching the source code of the demo EXE as well.

  LabVIEW sequentially launches 20 cases of "Idel_EXE.exe" who are getting a Notepad and returns information.

  This description is exactly what asynchronous call and collect is supposed to manage.  'Call' treats only the controls, move the VI 'in' data you call.  The "wait on asynchronous Call" does the rest - if the called VI has done and wants to pass 'out' data, this function provides the values.  As I have indicated, if the called VI is still ongoing, wait for asynchronous can expire, return an error (which you can use as a signal 'Wait a little bit longer').

• Why the plugin-container is very use 50% of the CPU?

  The container.exe - plugin in firefox 4.0 use about 50% of the CPU it forces worst response time for other applications that are running.

  Please check if Firefox is running in Windows compatibility mode - see here.

  Otherwise, check the extensions, you can run - see here.

  If still no luck, please have a read through the article Firefox consumes a lot of CPU resources for other causes possibly.

  Feel free to contact Firefox support again if you still have problems.

• Firefox, or the Profile Manager will start. In my task manager, the process uses 50% of my cpu but does nothing. I like browsing with firefox, how do I fix?

  I tried to restart my computer, the I tried to uninstall and reinstall uninstall, delete all files of firefox and folders, then reboot and then reinstall. Also, I tried to open the Profile Manager to edit my profile. After you have reinstalled several times and try to open the Profile Manager before launching firef0x, I got the firefox crashed window and the process in the Task Manager always uses 50% of my cpu. The most recent strike and then re - download gives me an error "the file is corrupt" and will not even install the program.

  Kill the process that you see, including any plugincontainer.exe, only once firefox has stopped running don't try to update.

  Completely unexpected instances of firefox running can sometimes be the result of malware activity.

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

  See this article from Adobe support under the heading of 'Last resort': Adobe Forums: how to fix protected Flash Player for Firefox mode?

• Solution for Google Chrome (Helper) by using a lot of ram and cpu on mac os x

  Hi all

  Some people have several tabs of google chrome, and it's using a lot of RAM. It also causes the fan go crazy sometimes. I looked for a solution for centuries, but no solution has allowed, until I stumbled upon the simple solution to use a google chrome extension that hibernates unused tabs. The problem has now completely disappeared.

  There are a few different extensions that Hibernate unused tabs, but the only extension which has enough options setting to do what I want, is called "The Great Suspender".

  You can set the time, after which the Hibernate (sleep) tab. The tab automatically resumes when it focuses on, (i.e., you don't need to then also click on a specific button). And the tabs of the extended day before will remain in hibernation after you restart the computer.

  There are many other parameters that can be changed. (After you have made changes, don't forget to click the 'save changes' button.)

  I hope this helps.

  Thanks for the tip.

• the process Svchost.exe to netsvcs uses a lot of memory (~ 600 MB) and 100% cpu

  I have windows xp edition sp3 family. I hit the power button to hibernate the pc but I think an automatice update was running.  Pc crashes when windows resumes after hibernation. I forced a re-boot, but now the svchost.exe to netsvcs process uses a lot of RAM and CPU. I have a Dell Dimension 8250 with 1 GB of RAM. Svchost uses > 600 MB of memory and 100% of the CPU unless I have stop the DHCP service. When I stop DHCP the svchost stops using CPU and memory affected slowly decreases to about 150 MB and remains at this level. But without DHCP I do have access to the network.

  After installing SP3 recently I started having some weird problems, as I lost my printer and had to re - install the software. Also noticed that after re-booting and desktop appears completely empty, the screen turns white and the taskbar at the bottom will appear empty for about 30 seconds, then reappears. PC seems to be more slow tha before installing SP3.

  I've tried everything. Nothing stopped the svchost to chew all the memory, virtual memory and time processor. Had to re - install windows xp.

• 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!

  The extension Freeven pro is probably the problem. Only that disable and check again.

  If you have the same problem after having disabled the extension pro Freeven then, disable graphics hardware acceleration.

  You will have to perhaps restart Firefox for it to take effect, so save any work first (e.g. you compose mail, documents online that you are editing, etc.).

  Then perform the following steps:

  • Click on the orange top left Firefox button, then select the 'Options' button, or, if there is no Firefox button at the top, go to tools > Options.
  • In the Firefox options window, click the Advanced tab, and then select 'General '.
  • You will find in the list of parameters, the checkbox use hardware acceleration when available . Clear this check box.
  • Now restart Firefox and see if the problems persist.

  In addition, please check the updates for your graphics driver by following the steps in the following knowledge base articles:

  • Troubleshoot extensions, themes, and issues of hardware acceleration to resolve common problems of Firefox
  • Update your graphics drivers to use hardware acceleration and WebGL

  In safe mode hardware, acceleration is disable by default.

  Thank you.

• 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...

• Firefox uses massive amounts of memory (up to 2 GB and more)

  Firefox uses massive amounts of Ram, even when I have a tab open. It uses so much sometimes that my entire system freezes and crashes FF. I tried saving, deactivated all my plugins, but without success.

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

  See "basic troubleshooting: a new profile:

  • https://support.Mozilla.org/KB/basic+troubleshooting#w_8-make-a-new-profile

  There may be extensions and plugins installed by default in a new profile, so check that in "tools > Modules > Extensions & Plugins" in case there are still problems.

  If this new profile works then you can transfer files from the old profile to the new profile, but make sure not to copy corrupted files.
