Firefox.exe 2 running in background all the time I open Firefox

Whenever I open Firefox, there are two firefox.exe running the bottom everytime I open the browser. Whenever I try to close the other, it blocks all tabs that are on the browser, and whenever I have reload the tabs, it appears again.

I've scanned my computer several times with several antivirus, but there was no virus found. I also disabled the plugins that I thought the question was and rested Firefox, but he was always there. I restarted my computer, no luck in doing so. Uninstall and reinstall of Firefox has not even do the trick either.

The dual process of sky-rocket my RAM and CPU and it starts to get boring. Help, please! I appreciate any cooperation!

This could indicate that your Firefox uses a new feature 'multiprocessing '.

E10s

One of the changes in Firefox 48 + title is e10s, separating the process of browser interface process page content. The performance impact of this can vary a lot between systems: many users find more quickly, some are slower, for many, it's neutral. It is probably a bit more memory than if everything runs in a single process firefox.exe usage.

Are you using e10s?

You can check if you have this feature enabled as follows. Either:

  • button '3-bar' menu > '? ' button > Troubleshooting Information
  • (menu bar) Help > troubleshooting information
  • type or paste everything: in the address bar and press Enter

In the first table on the page, find the line "Multiprocess Windows" and see if the number on the left side of the fraction is greater than zero. If so, you are using e10s.

If you use e10s:

If you think that Firefox is not performing or now uses an unreasonable amount of resources, you can assess whether e10s is causing this problem by turning it off as follows:

(1) in a new tab, type or paste Subject: config in the address bar and press enter/return. Click on the button promising to be careful.

(2) in the search above the list box, type or paste the cars and make a pause so that the list is filtered

(3) double-click the preference browser.tabs.remote.autostart.2 to switch the value from true to false

Note: the exact name of this preference may vary, but it will start by browser.tabs.remote.autostart

On your next startup of Firefox, it must be run in the traditional way. Any difference?

  • Now, Firefox crashes only all the time

    Firefox has slowed to a crawl... taken advice on the support page to delete and rename the file "places.sqlite" in Manager files in Firefox. Now Firefox only crashes all the time. guess my decision to go back to the Explorer was made for me... can not solve the new versions of FIrefox crashes, slowness, errors... now only breaks down and the "places.sqlite. old"file I saved is gone now, so cannot yet go back to it...

    Firefox does not work at all... ?

    Sorry to hear about the accident. If you get the Mozilla Crash Reporter form, your Firefox could have registered some data that would help to find the cause of the problem. You can submit these data to Mozilla and share with the volunteers of the forum to see if it points to the solution. Please check the support article "Firefox blocks - ask for help" to get the procedure to get these crash report IDs since the topic: block the page and then after the most recent here.

    Note: If Firefox is not stable enough to use the subject: page crashes, the article also describes how to check for submitted crash IDs disk report.

    Also, and/or at the same time, could test you mode without failure of Firefox? Which temporarily disables extensions, hardware acceleration, and a few more advanced features of Firefox that could make it more prone to crashing on some systems.

    Does not work if Firefox: Hold down the SHIFT key when you start Firefox.

    If Firefox is running: You can restart Firefox in Mode safe mode using either:

    • button "3-bar" menu > "?" button > restart with disabled modules
    • Help menu > restart with disabled modules

    and OK reboot.

    Two scenarios: A small dialog box should appear. Click on 'Start mode safe' (not update).

    Hello

    Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • Click the menu button

      click Help

      then select restart with disabled modules.

    If Firefox does not work, you can start Firefox in Mode safe as follows:

    • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac: Hold the option key during the startup of Firefox.
    • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
      (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. This might help others with the same problem.

  • Why Firefox from writing so given all the time?

    I'm running Windows 7 x 64 and Firefox 8. In my task manager, I display the bytes of i/o to write to all processes. I found that Firefox is ALWAYS the process with the largest amount of bytes in writing, after that it worked an hour or two even though there are dozens of other processes. The only Web page is Google and all my plugins are disabled.

    Why Firefox from writing so given all the time?

    Firefox can be updated from the database of phishing protection or maintenance with other files as places.sqlite. It should be limited to a point if this was done.

    Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions of the origin of the problem.

  • Satellite Pro 4600: Win2k with SP4 - cooler run all the time

    Hello

    last week, I bought a used Toshiba Satellite Pro 4600 PIII, 1 GHz, 512 GB of Ram, WIFI and DVD burner. Great machine so far.

    After that I changed the FAT32 file system to NTFS and reinstalled Win2K/SP4 cooler runs all the time.

    TaskManager says that "THOT_KEY.exe" uses up 99% of the CPU power. Disabling this service reduces the power of the processor and the cooler was quite, BUT didn't really helped - lots of keys does not work.

    I ran a few utilities to disinfect as Kaspersky, NOD32 etc. to ensure that Ia´ve not taken some malware.
    Should I try a bios update or change some settings?

    Any ideas?

    Thanks for help

    Hello

    AFAIK the THOT_KEY.exe belongs to the Toshiba Hotkey utility that controls the various key functions.
    If you disable this service, you will not be able to use the FN keys more.
    I m not 100% sure why this service uses 99% of CPU performance, but perhaps that it s not completely compatible with the W2K service packs. Where did you download this utility? I found it on the page of Toshiba Europe!

    In my opinion, you should try to reinstall the system again. This is probably the key!

    Good luck

  • Upgrade to Win 8.1 the fan runs all the time and Raw (Silkypix) converter consume 100% CPU resources

    Hi, after upgrading to win 8 to 8.1 win my converter (Silkypix) raw program running extremely slow and consuming 100% of CPU. VAIO all updates completed, all Win 8.1 updates made. ATM Radeon HD 7500 M / 7600M (Maj) with 2 GB RAM dedicated.

    In addition, the fan works almost all the time that was not the case with Win 8.

    Vaio SVE1712Z1EB with 8 GB of RAM, i7 processor execution.

    SeanQ, after some time looking for a solution I finally found it on one of the vaio sites forum: it is the Radeon driver that must be installed from the Vaio support site. NOT the driver the latest AMD site. It does not solve the problem.

    I did as follows: device, graphics card, Uninstall Manager. Did not help. Went to AMD in Program files. Setup.exe has begun, but instead of installation, clicked on uninstall. In this way, I uninstalled the driver former AMD and bad news from the site of AMD. I had to manually uninstall the driver in Device Manager, several times. Finally, I went to the site of Vaio and tried updating the driver. He failed. Reset. Manually start the update of the Vaio AMD driver. Finally it worked.

    The fan is now more or less normal speed.

    Overall, I spent 15 hours looking for this solution. How much is my time worth? Just joking, I'm happy that I found the solution.

  • my pc CPU running at 100% for all the programs I opened / what is the problem and how to solve?

    my pc CPU fan runs very strongly & the processor running at 100% for all the programs I opened. DO NOT KNOW IF IT IS A VIRUS IN THE PC WAS WORKING FINE A FEW DAYS AGO. How can I solve this issue?

    Hello

    You did changes to the computer before this problem?

    Step 1: Check if the problem persists in the clean boot state.

    From your computer by using a minimal set of drivers and startup programs so that you can determine if a background program is interfering with your game or program. This type of boot is known as a "clean boot".

    Reference:
    How to configure Windows XP to start in a "clean boot" State
    http://support.Microsoft.com/kb/310353

    When you are finished troubleshooting, follow these steps to reset the computer to start as usual:

    1. click on start and then click Run.
    2. type msconfig and click OK.

    The System Configuration Utility dialog box appears.

    3. click on the tab general, click Normal Startup - load all services and device drivers and then click OK.
    4. When prompted, click on restart to restart the computer.

    Step 2: Also, look for error messages in the event viewer. If you find error messages after return the exact error message so that we can help you better.

  • e7240 CONSTANT NOISE OF FAN NOISY / FAN RUNNING ALL THE TIME

    We received 2 nine E7240s directly from Dell, one for me and one for my colleague. As soon as I turned it on to build for my colleague, I noticed that the machine was overheating and the fan made a noise. Dell offers an upgrade of the BIOS that has not changed anything. They then changed the radiator, even once, that does not change and since then, they have changed the motherboard. My colleague went on vacation, so I don't know if the problem has been resolved, however, my laptop day you do not overheat (also of course as it has done for my colleague) BUT THE FAN RUNS ALL THE TIME. So much so that I think that the person in the room upstairs is using his hairdryer. Dell has replaced the heatsink of heat and the motherboard yesterday, I did the same update of the BIOS and the problem is even worse. As soon as I turn the thing, the fan runs all the time making a big noise. My predecessor was the E6500 and I was not bothered by noises, he did.

    The 7240 made so much noise that I want to throw it out the window , seriously, I go back to my old 5 years e6500, which is now very slow, I can not just take constant hair dryer of the fan noise! I'm waiting for Dell back to me, but I don't see what else they can do.

    I suspect a problem of design with newer models, someone with a laptop computer Latitude 13 also mentioned it on the Forum, someone else with an e7240 also said "I noticed the fan turns most of the time - it's quiet, but you don't know is spinning."  I just implemented, so the CPU is busy enough. "A person with the e6320 says"and the fan is noisy and turns far too often.

    I just bought a new Dell Latitude E7240 with Windows 7 laptop and had the same problem with overheating and the fan is running loudly all the time. I just fixed it on my laptop, it may not work for everyone but just in case I walked it here.

    The index for me was that the question has happened at home, not at work.

    • Using the Task Manager, I found that a "svchost.exe" process was always running at 25% of the CPU, i.e. to take 100% of one of the 4 hearts. For this you need view all processes, and that's why you need a local administrator account if she asks permission.
    • With right click on this process-online 'Go to services', you can study what services are hosted by this instance of svchost.
    • For each of these services, try to stop one at a time (if it helps) and see if the CPU usage goes down. For me, a clue was a service stuck on 'Stop' but never stopped.
    • The service which for me was the "HomeGroup provider." That's why the issue has happened at home and at work. The laptop had spotted my homegroup on my home network, but had not been able to accede. Maybe a problem with IPv6 that I could not turn on my desk.
    • In the Services tab in Task Manager, get on the service properties, which set to Disabled Startup Type.
    • Restart the laptop, to ensure that the service is stopped.

    That did the trick for me, and now the CPU remains less than 5% when idle. This isn't the problem that the fan is noisy when the CPU usage is high, but for me what rarely happens now.

    If you want to access files and printers on your home network without the homegroup feature, you can still do that the old way:

    • Network and sharing Center-Online avancΘs => Homegroup Connection-online 'use user accounts to connect to other computers.
    • Also in the settings advanced: enable discovery network. and Turn on File and Printer Sharing.
    • Then, you can click on your wifi network => add a printer.
    • If your office does not appear, click on "Not listed", then browse. As long as the network discovery and printer sharing are enabled, desktop PC should appear and you can connect using your local Windows user name and password.

    Hope this helps someone.
