can not understand how to reset lost password master key

I read how to change but can not understand to do

Have you tried using the URL in the address bar chrome?

chrome://pippki/content/resetpassword.xul

If you use the chrome that url does not work, then delete the files key3db and signons.sqlite in the Firefox profile folder.

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

  • Help > troubleshooting information > profile directory: see file (Linux: open the directory;) Mac: View in the Finder)

  • I disabled toolbars. Now I can not understand how to get back them. Have no 'view' click.

    I went to view/toolbars and disabled my toolbars. Now I can not understand how to get back them. Have no 'view' to click on.

    In Firefox 3.6 and later Windows, you can hide the menu bar on "view > toolbars" or via the contextual right click menu on a toolbar.
    Press F10 or press and hold the Alt key to bring up the menu bar temporarily.
    Go to "view > toolbars", right click on the menu bar, or press Alt + V T to select to show or hide toolbars (click on an entry to switch from the State).

    The screen of my computer no longer turns. It is supposed to run it any way, I flip the screen, I can not understand how to solve this problem. I guess a child (best case scenario) or my husband (worst case) have been involved in this. But it drives me crazy. Any ideas on how to get that back in action?

    Hello

    What is the brand and model of the computer?

    Were there recent changes made on the computer before the show?

    This issue could be due to corrupted graphics cards drivers. I suggest you to update the latest version of the drivers of graphics from the manufacturer's Web site and check if it helps.

    I have photos I want to decrease the dpi on but can not understand how with the Gallery Windows. I have Windows Vista operating system.

    ===============================================
    You can resize a picture in WLPG but if you want to change the .dpi you
    need a different application.

    Information about resizing...
    Right-click on one or more selected inches... Choose... "Resize" in the menu.
    Choose a format, access a folder to save in the left click the ' resize and
    Save "button. (I suggest that you save the photos resized in a new folder
    to prevent the replacement (replacement) the originals)

  • my windows pc very experience 1, I am embarressed to admit that I can not understand how to configure the windows/outlook e-mail system. This pop and smtp or what ever Q was, I still can't understand.

    I'm unable to set up Outlook, or now called windows mail, I think. but for the life of me I do not understand how to configure the e-mail program that comes with now it windows Vista 64 that came on my new pc.  can someone please?  Thank you

    Windows Mail is/was not Outlook.

    Windows XP e-mail program called Outlook Express.

    Outlook is a part of the office.

    Windows Mail in Vista is the replacement of e-mail for Outlook Express (XP) program.

    Read this section on how to set up Windows Mail in Vista:

    http://www.SimpleHelp.NET/2007/02/07/a-beginners-guide-to-setting-up-Windows-Mail/

    Link above has an easy to follow Guide to set up Windows Mail.

    Contact your ISP (Internet Service Provider).

    They offer your broad band/Dial-up connection.

    Ask them to:

    username
    password for your service account to wide band/Dial-Up with them

    Server of incoming POP3 mail
    outgoing mail SMTP server

    The above information is required to set up Windows Mail.

    ISPS are usually happy to help you set up your email account.

    See you soon.

    I don't know how to reset the password - it told me to remove the admin password by entering a blank password in the new and confirm

    password, but it won't let me move down.

  • I TB 24.6.0 and I deleted the bar menu or a tool of my address book and I can not understand how to get it back.

    I'm trying to understand how to efficiently copy a contact so I can add the contact information to an e-mail. While experiences I disabled the menu bar or the toolbar in my address book, and now I can't figure how to get it back. So we can say, I have two questions I would welcome suggestions:

    1. How can I get my menu/return tool bar in my address book?

    2. How can I effectively copy and paste contact information?

    Thank you

    Sounds like a good plan. Version 31 and above all is a mess right now. I stay at v24.6 until they get the problems developed. Version 24.7 went out before v31, but I've never had one so I don't know anything abut it or what fixed it.

    This is the page to previous version.
    http://FTP.Mozilla.org/pub/mozilla.org/Thunderbird/releases/
    Find the version you want and click on that selection.
    You want to select your operating system. Win32
    Then the language. EN-US
    Then, run the .exe file.

    Your profile with all your emails and settings are separated although they should be performed when you install the older version. Make a backup is not a bad idea at any time, or just to be safe on the version change. I use Mozbackup. http://mozbackup.JasnaPaka.com/

    Automatic update options are found in Tools-Options-update.
    I usually set mine to ask first, but with the V31 disorder, I have disabled the option to control even. I want to assure you that I do not get this version for a while.

  • Can not understand how the adjacent color elements

    Hello, I am a new user of illustrator and it's been a frustrating experience.

    I just want something simple... the linework, color using the fill color or a clipping mask. However I can't find how to do.

    Whenever I tried to fill color or a clipping mask, he selects the wrong part of the object and does not follow the line. Please see the attached picture. Why is happening. Why Selection tool cut it like that?

    (you see I tried to color eggplant, but the purple part is all wrong...)

    I would be grateful if someone can help me.


    Also, I find that it is incredibly difficult to choose the color that I want to leave this little rectangular box on the right side. How can someone find the color they want in this tiny color box?

    Is there anyway I can have a color wheel, or is it more easy way to choose the color from the palette?

    Use the closed paths (more intuitive) or paint (smoke and mirrors).

    In this example, you must continue drawing the pink form (on the green form) with the pen until the path from the farm. Then go behind the Green shape by using the layers panel or cut and paste behind.

    Or you can create a live painting of this group and colour it with the Live paint bucket.

    I think you'll learn more by the way, with closed paths. Some people think of paint as cheating.

    Apple has blocked 'file manager apps' access directly at the beginning of iOS with iOS 8.3 file system.

    The only way that some files are accessible through these types of applications is if the files are marked for sharing files (accessible via iTunes on Mac/PC) by the developer of the app. Actually, you don't need a ' file manager app "since the sharing of files in iTunes already allows to access files directly via iTunes in the first place.

    Hello

    I would ask you to contact the manufacturer of the computer for the installation of Windows XP CD and run the sfc scan to check if any system files are corrupt and can be replaced.

    Method 1.
    Let us first start the sfc scan and check if there are any file system corruption.
    a. to do this, click Start, click programs, accessories principally made, right click Guest and then click Run as administrator. If you are prompted for an administrator password or a confirmation, type the password, or click on allow.
    b. type the following command and press ENTER:
    sfc/scannow
    The sfc/scannow command. analyzes all protected system files and replaces incorrect versions with appropriate Microsoft versions.
     
    More information on SFC scan found in this document:
    Description of Windows XP and Windows Server 2003 System File Checker (Sfc.exe)
    http://support.Microsoft.com/kb/310747

    Method 2.
    If the problem persists, then create a new user profile and then copy your current users assigning to this profile. For more information, see:
    How to create and configure user accounts in Windows XP
