My windows 8.1 does not work with the new Firefox update. It worked before the upgrade. How can I fix it?

After Firefox updated itself automatically, Firefox would not work. I couldn't go online on Firefox because it doesn't open at all. The old Firefox worked.

You may have seen this article during the process to submit your question, but just in case:

Are you familiar with Windows Task Manager? It allows to determine whether Firefox is present in memory and to cease so that you can try to start again.

To access the Task Manager, press Ctrl + Shift + Esc. You will need to approve the program to make changes to your system. The 'Applications' tab usually has an entry for every visible window. I guess that Firefox will not be there, but if it is and you do not see the window, it's a different problem.

The "Process" tab will list firefox.exe if Firefox is running in memory, or if it has started and stalled. If it is just sitting there, click it, and then use it button end process to kill him.

Then, try to start Firefox in Safe Mode. It is a standard diagnostic tool to disable some advanced features of Firefox and extensions. More info: questions to troubleshoot Firefox in Safe Mode.

Hold down the SHIFT key when you start Firefox.

A small dialog box should appear. In the dialog box, click on 'Start mode safe' (not reset).

Does it work?

    It looks like your dad keybaord was put at the disposal of the UK.  This can happen if you accidnetally you press a special combination keys that been implemented as the means of getting that deliberately.  Here's what to do: -.

    1 go to Control Panel, region & language, keyboards & languages, Change keyboards, general tab, select the correct keyboard in your area * if isn't one already shown [click on Properties... to see a preview of the keyboard layout] or click Add... & Select a new keyboard from the list [while you are in the list, click on the Preview button to see a preview]. When you have finished adding a new keyboard, move it to the top of the list using the buttons on the dialog box.

    [* The region for which the keyboard was made and for which its route has been set.  [I understand that there is a "US International keyboard" who suffers from this confusion between change quite easily, unless you have a need for special versatility, choose a keyboard layout United States specific instead if you find that this is what has been implemented on your system]

    2 then go into Control Panel, region & language, keyboards & languages, Change keyboards, tab bar of language and, if you regularly change the language settings, make the hidden language bar.

  • Windows media player does not work as no driver DVD

    Had to format drive (trojan) & reinstall Windows XP home. Now Windows media player does not work as no DVD driver download from Toshiba site?

    Hello

    Usually the Windows media Player is not able to read DVD movies IF no plugins were installed.
    To watch DVDs, you can use programs such as WinDVD or PowerDVD.
    These programs are designed for the DVD play!

    But you can also visit the Microsoft Web site and search plug-ins for Windows Media player.
    Then you can download and install to play a DVD with WMP

  • My CD-ROM/DVD-Rom drive & the Bison Webcam built into my laptop. Does not work after I upgraded from Vista home premium to Windows 7 Home premium.

    My readers Optiarc DVD - RW AD-7530 ATA Device DVD/CD-ROM & the Bison Webcam built into my laptop. Does not work after I upgraded from Vista home premium to Windows 7 Home premium.
    Although of course, the CD-ROM drive worked during the upgrade.
    I noticed that when I turn firstly on the laptop, the last two lines of the front entry from Windows 7 are the following.
    PXE - E6i:Media Test Failure, Check Cable
    PXE - MOF: Exit PXE Rom
    During the audit of each Properties in Device Manager devices", I learned that they both work correctly.  In the list in the printers and the @Devices the only Webcam shown is also a "USB 2.0 Camera"
    Can someone help me please?
    Best regards
    John

    Besides what abdelhak says:

    The message of PXE boot that you receive when you start your computer has nothing to do with your CD/DVD-Rom drive. Your computer uses a PXE boot method to attempt to load Windows from a location on your network. Since you do not have this configuration, it is safe to ignore it. If it slows down the startup time of your system, contact your manufacturer and ask them for instructions on how to "disable PXE Network Boot of the BIOS.

    Hope this helps,
