42 Firefox firefox.exe leash * 32 process open after it is closed

Every time I close Firefox 42.0 it leave a firefox.exe * 32 open process. If I open & close Firefox 10 times, I'll have 10 occurrences in the Windows Task Manager. They are always different sizes. Using Windows 7.

Solved. Free Download Manager extension is causing the problem. Disable it and not more than left - open Firefox process.

  • Firefox will not display on the screen even though with Process Explorer, I see active Firefox.exe but no CPU usage

    I use Firefox as default browser v10.0.2 on Dell XPS8300 Intel Core i5 and Windows 7 Ultimate and Compaq Presario CQ57 IO IO Intel Core i3 and Windows 7 Home. More frequently on the (approximately 90% of attempts) that Dell (50% of attempts) Firefox will not display on the screen when I click the icon. Cannot display other programs when it happens. I expressly say display because I believe that Firefox has started. To work around the problem, I installed Process Explorer on both machines and launch this program first, then click on the Firefox icon. When the problem occurs I see process Firefox.exe in the list of processes; some CPU consumed but, then, no CPU activity. If I click on the Firefox icon, yet another process opens in the list of processes, but with the same answer - some consumed CPU and then no CPU activity. If I have 2 processes running and kill the process from the 1st, the 2nd poster and then everything is normal. If I do not open it treat a 2nd, but kill the 1st process then click the Firefox Firefox is displayed and all then is normal. This problem has occurred since the original on the two new machines installation. I have updated the video drivers on both computers.

    OK, let's see if we can solve this problem and make it work for you!

    First of all, if you start Firefox in safe mode (restart your computer first, then when you open Firefox, hold down the SHIFT key) it starts more reliable? This is usually caused by a defective module. If this does not help, then restart Firefox, go to the Firefox, then add-ons button and disable your extensions one by one until you find the troublemaker.

    Also, try to update to Firefox 11, it has several bug fixes that might make life easier here.

  • 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?

  • Two process firefox.exe

    Hello.

    Earlier, I noticed a slight change in the behavior of firefox, slight delay when you allow scripts in a website (via the plugin NoScript).

    I couldn't work on what was causing it, I thought it was maybe just an update to NoScript itself introduce an error, but then I came across two firefox.exe process in the Task Manager.

    Two of them open when I open firefox itself, is just the location of basic Firefox in the command line, while the other has a long argument. The long argument is that: "C:\Program Files (x 86) \Mozilla"-contentproc - channel = "(numéro long ici) '-greomni ' C:\Program Files (x 86) \Mozilla Firefox\omni.ja"-appomni "C:\Program Files (x 86) \Mozilla Firefox\browser\omni.ja"-appdir "C:\Program Files (x '"

    Is this a normal behavior? I tried to create a new profile and run in safe mode, but the two processes always opens. I ran malware scans and they came to own.

    Thank you in advance.

    Edit: Read a bit about the new changes to firefox. This could be from the electrolysis? I checked on: supported and turned on for me.

  • Second firefox.exe appearing in the process in Windows Task Manager...

    Hi all!

    I started facing this problem a few days ago and do not know what is the cause:

    In my Windows Task Manager, there are two firefox.exe that appear under the process (under Applications, Firefox only appears once). I used to complete the process to close each of the firefox.exe that appear and the result was special. Depending on whether one I finish, either the window closes completely as well as all tabs or hangs the tab that is currently open and I get the message: "bad new first: this tab broke down."

    I scanned my computer with AVG for viruses and everything was clean back. I've also scanned with ESET for malware and nothing was found.

    Any idea what I can do to fix this? Any help would be appreciated.

  • After the update to 15.0.1 Firefox open from C:\Program Files (x 86) \Mozilla Firefox\updated\firefox.exe

    After the 15.0.1 update this afternoon on a machine 64 - bit Windows 7, I restarted Firefox. Immediately liked began to display warnings that firefox.exe was not a recognized program and needed plugin container, the SVC host access and other things. Weird. So I look in the Comodo and Explorer and it says that the process runs from this path:

    C:\Program Files (x 86) \Mozilla Firefox\updated\firefox.exe

    But there is no update file. This happens even when clicking on the firefox.exe file in the Mozilla Firefox folder.

    Is this normal? It does not seem right.

    Too bad. I restarted the computer and everything seems to be back to normal - firewall and the paths are now correct. Then. anyone having this problem - try to restart the machine. Never had that after a Firefox update before so don't think of him.

  • When I close Firefox, the window closes, but the Firefox.exe process and the plugin container continue to run in the background and should stop using Windows Task Manager.

    This happens frequently. Something in Firefox continues to operate even when the program is closed. The process must be stopped before I can open Firefox again.

  • Firefox.exe suddenly only 2 k (and IE 1 KB) & flagged up as a malware

    January 13 (2015), I was surprised to find my anti-virus (Pure 3.0 at the time) Kaspersky software tracking upward of what follows as a malware (trojan):

    Firefox.exe C:\Program Files\Mozilla Firefox\firefox.exe HOUR: Trojan.WinLNK.StartPage.gena
    Iexplore.exe C:\Program may Explorer\iexplore.exe TIME: Trojan.WinLNK.StartPage.gena
    eBay Sidebar for Sidebar C:\Users\David\Desktop\eBay Firefox.lnk for Firefox.lnk HOUR: Trojan.WinLNK.StartPage.gena

    I followed the instructions to the quarantine and re - start. No problem. After re-booting, I couldn't access Firefox and discovered that he had indeed been quarantined - with IE (which I use rarely) and eBay Sidebar for Firefox (which I have not used for a long time). On the restoration of these, they are still identified as malware. Further investigation revealed that firefox.exe was only 2 KB - and that is only 1 KB.

    Kaspersky was advised to switch to total security, that I did and it has continued to identify the files as malware. Full virus controls, including safe mode, is not revealed. Run a suite of recommended anti-malware programs don't have pick up a limited number of bits and pieces (and I deleted) that Kaspersky has not, although my research on the net pointing everything be the kind of things that produce advertisements on browsers... not something that would erase or rename programs (I don't see bad ads though, perhaps because of my settings in Firefox Kaspersky and NoScript).

    Kaspersky feels firefox.exe has been altered (on 2 k, it is certainly not right) - Although that corrupt is another question. All other files \Mozilla Firefox seem to be there, and I have no problem with other software or files on my PC (just those three). Again the same thing happened to IE at the same time. That is a hard drive failing very little likely indeed - but it makes me suspicious that there was * something * deliberately made that Kaspersky did not pick up. However, it would be unusual for decent antivirus software like Kaspersky miss something. In addition, the same question must occur widely around the same time, because if everyone around the world lost their browsers he would have made the news - not to mention advertising malware that corrupts the two browsers being rather doomed to failure!

    Either way, the desktop shortcuts have been replaced by the Windows icon by default for programs that do not have a shortcut to measure. And by clicking on what was the shortcut of Firefox opens a DOS window, which closes immediately; IE does the same thing but a "16-bit MS-DOS Subsystem" error box appears (these are the days!) with:
    C:\Users\Public\Desktop\Internet client.lnk
    NTVDM CPU has encountered an invalid statement.
    CS: 123f IP:012d OP: 8f 9f af 6th ba choose 'Close' to terminate the application.
    [By clicking on 'Close' or 'ignore' both close BACK - and that's it.] [No virus or something similar is picked up and four anti-malware programs, I am using now show that my system is clean.

    So my questions are:
    (1) any thoughts on what happened?
    (2) I need to get Firefox working again. Can I simply copy firefox.exe from another machine and replace the existing 2 k firefox.exe and everything should be good, as it was before... or it is not as simple as that? (I understand that Firefox keeps preferences, etc., in separate files).

    Thanks in advance for your comments.

    Dave

    Sorry, you had this problem

    It my be possible and work if you replace the firefox.exe problem

    However that could cause problems and the solution would be to download and install Firefox again by an official site, and by using a pure install involving the removal of the existing program files. (Care to leave the files and folders from one Firefox profile. In fact, it would be interesting, as a precaution suspenders belts ; Locate and save first)

    As to what happened, you gave a well-reasoned and intelligent summary, but after the event, it's going to is almost impossible to define. Sometimes the AV brand and/or & false positives especially temporarily if not totally updated.

    Clean reinstall it

    Some Firefox problems can be solved by performing a clean reinstall. This means that you remove Firefox program files, and then reinstall Firefox. Please follow these steps:

    Note: You can print these steps or consult them in another browser.

    1. Download the latest version of Firefox from mozilla.org office (or choose the download for your operating system and language on this page) and save the file to install it on your computer.
    2. Once the download is complete, close all Firefox Windows (or open the Firefox menu

      Click the close button

      ).

    3. Remove the Firefox installation folder, which is located in one of these locations, by default:
      • Windows:

        • C:\Program Files\Mozilla Firefox
        • C:\Program Files (x 86) \Mozilla Firefox
      • Mac: Delete Firefox in the Applications folder.
      • Linux: If you have installed Firefox with the distribution-based package manager, you must use the same way to uninstall: see Install Firefox on Linux. If you have downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
    4. Now, go ahead and reinstall Firefox:
      1. Double-click on the downloaded Setup file and go through the steps in the installation wizard.
      2. Once the wizard is completed, click to open Firefox directly after clicking the Finish button.

    More information on the resettlement of Firefox can be found here.

    WARNING: Do not use an uninstaller to third parties as part of this process. This could permanently delete your Firefox profile data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and passwords saved. They can be retrieved easily unless they have been backed up on an external device!
