At startup, the screen displays two websites of mozilla instead of one, why?

To start Mozilla, each time, two sites of Mozilla display. We're 'Mozilla Firefox Start Page' and the other is the screen "on the first installation of Mozilla". Installing the first page is displayed on the screen. Both are active.

I would like to see a single one. I don't know what to do.

You can check for problems with preferences.

Delete a possible user.js file and files numbered prefs-# .js and rename (or delete) the file prefs.js to reset all the prefs by default, including the prefs set via user.js and pref which is no longer supported in the current version of Firefox.

You can use this button to go to the Firefox profile folder currently in use:

    in order to write the information to a website in a MS word document, I want to put the site to display browser so the document MS word on the screen at the same time (each 1/2 of the screen (left and right view). How can I do this? I am technically challenged so tell me in the jargon of the primary school

    I can't test this on Windows 10, but...

    On Windows 7, if you hold down the keyboard Windows key, then press the right arrow key, the currently active window will change its form. By example, if the window is maximized it will change occupying half right side of the screen. Hold the Windows key and pressing the arrow key right to scroll to the right, left and restored/resizable. To maximize, use the up arrow key.

    I hope you can use this keyboard shortcut hidden to set each application to the half of the screen easily without having to manually extendable/retractable and move windows. And it's a cool thing that you can share with other people.

    If restore work not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:

    Download the ISO on the link provided and make a record of repair time it starts.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

    When you have changed that, insert the Bootable disk you did in the drive and reboot.

It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC. Technically, we could re-create this installation with downloadable media media freely from Microsoft (namely the Microsoft WAIK, several gigabyte download); but it is pretty darn decent of Microsoft to present Windows users who might not be able to create such a thing on their own.

    Read all the info on the website on how to create and use:

    It's a very good Vista startup repair disk.

    You can do a system restart tool, system, etc it restore.

    It is NOT a disc of resettlement.

    HY, need help...

    I've had this laptop for 2 years and never had any problems, but a few days when I move the screen to open, adjust or close the screen shakes and display different colors.

    Hello

    In my opinion it s definitely a hardware problem.
    Either there is something wrong with the connection or the screen itself.

    It seems that you have no experience in the laptop repair and so there is no sense in doing this.
    First of all, I doubt that you have all the tools to check what part is affected and then you could damage other parts while removing the procedure.

    So I think that you should get in touch with local laptop technician and should first try to know what's exactly wrong
    Then you can decide what you would then do

    I mean the screen is one of the expensive components for laptop and possibly it s not worth buying a new

    I have watched the tests diagnostic and repair details and the cause of found root shows that Startup Repair tried several times but still cannot determine the cause of the problem. Last night, I'm sure it says registry is corrupt, but I don't see something like that today?

    Change the screen resolution

    Screen resolution refers to the clarity of the text and images on your screen. At higher resolutions, items appear sharper. They appear also smaller, so more items adapted to the screen. At lower resolutions, fewer items adapted to the screen, but they are larger and easier to see. At very low resolutions, however, images may have serrated edges.

    It is disheartening to know that have problems you with the display of the computer. I get it right you computer display is divided into 3 parts.

    I need to ask you some questions to help you best.

    1. What is the brand and model of the computer?

    2. were there any changes (hardware or software) to the computer before the show?

    Download and install the drivers from the manufacturer of the computer display and check.

  • Export options for the screen display?

    I want to do a screening to export a lot of photos that will be visible on the phones, tablets, and TVs.

    1. is the best sRGB color for the on-screen display space?

    2. I'm culture images in 16 x 9. All the megapixels in these pictures are wasted for the display? I'll change the resolution to 72, well that what should I do with the megapixels?

    Thank you.

    It was not the case for a long time.

    A pixel is a pixel. 2000 pixels will be 2000 pixels to display. the question is that of the device. The native resolution of a in 20 Apple Cinema Display is 1680 x 1040 so a 2000 pixel wide image will be too large for the screen at 100%

    On the other hand, the iMac 5K has 5120 x 2880 the same 2000 pixel image would take less than half of the screen.

    The 'thumb' of 72 240 or 300 resolution concerns only thumbs on a sheet of paper, not a screen.
