    "Firefox is already running..."

    Whenever i open firefox i get that message "firefox is already running......" but then another firefox window opens and i can just use it normally, but that error-message-window always appears in the beginning and it seems useless...
    how can i get rid of it?

    Hello, every time you get this message press Alt+F2, type in
    Code:
    killall firefox-bin
    and start firefox again

    this will kill the already open firefox process.
    If there's no such process (firefox-bin) while you open firefox and you get the message again, then it is probably a firefox bug.


    But, for example, do you take this error message if you restart your PC and open firefox (once) ?

    Open the terminal (Applications > Accessories > Terminal) and enter
    Code:
    killall firefox-bin
    Then restart firefox, if that doesn't work try rebooting.

    You are probably double-clicking the little icon on the top panel. Just single click it.

    regards,

    Hello unapendeza, as terminal use must be avoided if possible for new users, I'd say that Alt+F2 (supported by unity bar as well) is preferable.

    Why should the terminal be avoided? Too traumatic? Lack of typing skills?
    In fact launch Firefox from the terminal and see if you detect any error messages. This way there is no question of double-click.The command would be
    Code:
    firefox

    Why? As a new user I think that other new users should be introduced to the terminal right away, besides it's not a complex command.

    OFFTOPIC: Well i think that completely new users have to get used to the sytem first before going through terminology, im not the only one with this opinion: http://ubuntuforums.org/showthread.php?t=1775713

    This perception is understandable but to overcome the reticence to use the terminal allows you to learn your system faster, in depth and removes you from the Windows mindset of only GUI control. The terminal has its place among all users.

    The original poster didn't say if he's using FF 4 or FF 3, the earlier FF had a problem with continuing to run processes and I haven't had much (but a little) of the same problem in FF 4.

    As to how to kill processes, the simpler the better. Many committed Ubuntu users don't realize that the future of operating systems is invisibility (that's why Chrome is hiding Linux under its browser in the "revolutionary" Chrome OS.) I don't love Google, but I agree that operating systems are inherently boring functional platforms for useful or enjoyable software, and should just bloody work with as little fuss as possible for users who should and will focus on work or fun with the software, not with the OS.
