How can I disable pages 'First Run' and 'Whats New' projection after Firefox update to all users who log on to a system.

I am a system administrator and need a way to set a global preference not to open the Whats New and first run pages. I found the preference browser.startup.homepage_override.mstone in the user profile but you want to be able to put on a global scale.

Use a mozilla.cfg file in the Firefox program folder to lock the prefs or specify default values.

Place a local file - settings.js in the defaults\pref folder where you will also find the channel - prefs.js to specify using mozilla.cfg file.

pref("general.config.filename", "mozilla.cfg");
pref("general.config.obscure_value", 0); // use this to disable the byte-shift

See:

You can use these functions in mozilla.cfg:

defaultPref();  // set new default value
pref();         // set pref, but allow changes in current session
lockPref();     // lock pref, disallow changes

  • How can I disable the double click to a new tab in Firefox?

    I just installed the latest version of Firefox, and now I'm faced with a new problem. When I try to open a new tab I click twice on the top bar, and it's annoying me. I used to open a new tab by clicking on an icon next to any tab and now this icon is moved to the top right corner, and it seems there is no way to open a new tab except by double clicking on the top!
    How can I find this icon instead of previous to open a new tab just with a single click.
    Thank you

    How can I disable the first elements adobe from my computer crashed

    Hi Franks,

    This probably should have been posted in the Premiere Elements forum, as this forum is a place of social discussion.

    However, you can simply install Premiere Elements of the new computer and activate it. If not, then you will need to contact Adobe customer service and use the 'chat' option - they will help reset your activation:

    Hello

    I don't know, but there is no way you can stop these sounds to emerge, they are built better reliability.

    All that you can disable is the sound when a new email arrives. Although I have no reason to make this wide, but if you want, here are the steps:

    Open Thunderbird > go to Edition on the topbar/tasks bar > click Preferences > in the general tab by default, clear the play a sound.

  • How can I disable my fax machine and turn it on only when necessary = officejet 8600

    Fax interferes with my answering machine when the printer is turned on.  I would turn off and only turn it on when I'm expecting a fax.  How can I do this?

    Hey Waddas,

    Then have that AUTO answer, the fax system is blocking voice messages to come through?

    You said earlier that you only need fax function when you know that a fax is coming through.  If you know that a fax is coming through, you will then know to be able to hit the reply on the printer button.  The auto-answer being set to OFF should allow voice messages to come through and allow the user to manually accept a fax call.

  • How can I MOVE buttons on taskbar to a new location without having to close all programs and resume in the order I want?

    I like to keep the buttons in my taskbar has organized with the browser and messaging on the left, followed by Windows Explorer and other items. If they get out of order or programs are loaded into a different order, how can I MOVE the buttons to a new location without having to close all programs and resume in the order I want? In addition, sometimes, one of program buttons seems in itself to migrate out of place and I need to get back to where it should be: same problem.

    Hi shohareZohre

    Thank you for using the Microsoft Answers Forums!

    The task bar is the horizontal bar at the bottom of your screen time. In contrast to the office, which can get obscured by the windows on top of it, the taskbar are visible nearly all the time. It includes four main sections:

    ·         The Start button, which opens the start menu.

    ·         The Quick Launch bar, which allows you to start programs with a single click.

    ·         The middle section, which shows you what programs and documents you have open and allows you to quickly switch between them.

    ·         The notification area, which includes a clock and icons (small pictures) that communicate the status of certain programs and computer settings.

    Add or remove programs on the Quick Launch toolbar

    The Quick Launch toolbar is located on the task bar and is a convenient way to open programs. You can add or remove program icons in the Quick Launch toolbar so that you have easy access to the programs that you use frequently.

    To add a program icon to the Quick Launch toolbar

    Click the icon for the program to add (you can find most icons of programs on the start menu or the desktop) and then drag it to the Quick Launch toolbar.

    Note: If you don't see the toolbar tools quick launch, right-click on an empty area of the taskbar, click Toolbars, and then click quick launch.

     

    To remove a program to the Quick Launch toolbar icon

    Right-click on the icon of the program and then click Remove.

    Notes: ·         Delete an icon from the taskbar does not remove its corresponding computer program.

    ·         If you want to stop showing a toolbar on the taskbar, right-click an empty area of the taskbar, point to toolbars, and then click the item that you want to stop broadcasting.

    NOTE: The ability to move the programs in the taskbar is not possible in windows Vista but the same functionality is available in Windows 7. Please see the link below.
