    How do I prevent Firefox from opening multiple processes in Windows 10?


    About half the time when I use Firefox, it opens multiple processes. These don’t show up on Task Manager; I find out only when trying to open Firefox again, having thought it was shut down.



    Following posts on the Microsoft boards, I’ve set browser.tabs.remote.autostart to false; it makes no difference.



    Suggestions? Thanks!

    :)

    Unable to open multiple Firefox windows after first successful opening!

    Thanks for the replies but I think it is more serious than what you have all given me answers for.
    When I turn the computer on and either click the Firefox icon on my desktop of one of my Rocketdock icons it will open up a page. However, if I proceed to do the same again, desktop or Rocketdock, nothing will happen except briefly flash the hourglass next to the cursor.

    An update to this is, if I then close the one and only window I have been able to open I cannot open anymore Firefox windows and I just get the brief blink of the hourglass.

    As mentioned in my first post there is no problem opening multiple tabs in the first and only Firefox window.

    Unable to open multiple Firefox windows after first successful opening!

    I turned my computer on this morning, as per normal and without having any previous trouble, and I cannot use Firefox to open a window more than once, be that from my desktop or Rocketdock.

    For example if I have used Rocketdock to open Yahoo, which is setup to use Firefox by default, it will work. However, if I then attempt to use any other Firefox assigned icon or the icon on my desktop all I get is a brief flash of the hourglass and then nothing.
    I do not, however, have any problems opening up multiple tabs in that one open Firefox window.

    I have run Registry Booster, CCleaner etc and I have also re-installed Firefox but without any luck.

    Any ideas?
    Cheers.

    How do I prevent Firefox from opening multiple processes in Windows 10?

    Windows 10 Tweaks

    Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

    Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

    • Open a new Explorer window.
    • Click View in the ribbon.
    • Click Options.
    • Under General, next to “Open File Explorer to:” choose “This PC.”
    • Click OK
